902 MHz EME Challenge Part II

March 10, 2024

After two sessions trying to get the NXP LDMOS pallet to play nice, I replaced it with a W6PQL pallet. It took some fiddling to re-jigger the 12 vdc bias circuit, re-do the 50 vdc VDD lines, and solder the RF input and output coax in place. Slipping two layers of index card stock between the circuit board and the heat-spreader works really well - otherwise the copper heat-spreader draws the heat off too fast to get a good, clean solder joint. I could even solder the conformable coax in place with a 45 watts HAKKO soldering station cranked all the way up. 

Today was the smoke test. 3 watts of drive = 400 watts. That's 21 db gain which is very nice! I have some level setting to do with the transverter's 144 MHz drive level, even at 0% power indicated, my IC-9700 hits the transverter a bit too hard. A 3db 10W attenuator is on the way. 

I've also discovered my usual operating spot in the barn just south of town is not a good location for 902 EME reception. There are just too many 902 - 905 devices chirping away across the band. For the next test I'll retreat to the mountain cabin just north of Yellowstone Park as soon as snow comes off the access road.

In the meantime I've been streamlining the station's cables and generally getting things ship-shape for some summer travels with 902 and 1296 gear.

Onward!

Finished soldering the .250" conformable output coax in place.  Note the card stock to be removed.


The 902 MHz Moonbounce challenge

 February 10, 2024

There seems to be a sudden surge of interest in achieving Worked All States on 902 MHz. W5LUA has just nailed down WAS #1 and N1AV has 48 States in hand. I was asked if I could active Montana and other western States via the moon to help the cause. Sure! 

KA6U has been out and about including 902 EME on his epic road trips, so folks have been upping their W.A.S. totals already thanks to his Herculean efforts. Here's a taste of his activity.

Many hands make a 902 moonbounce station - Ian, W6TCP sent me a NXP Semiconductor 915 Mhz test pallet to work up into a fully functioning amplifier. I managed to stick things together in two four hour work sessions to create one of my "KISS" amps, but but initial testing was a bust. After some expert help from W6PQL, we can now say, "It's alive". I should have 350 watts to play with given the drive from the transverter. The nice thing about the NXP pallet is that the bias voltage is generated directly from the 48 VDC  VDD supply.

N1AV plyed me with a loaner 144 MHz to 902 MHz transverter he had picked up along the way. W2HRO sent west a patch dish feed for my 2.4M dish. I've have two superb WD5AGO pre-amps in hand, so I'm close to first RF on my sixth EME band! Later this month after a long-planned trip south to bask in the warmth of Mexico we'll see what can be done.

I understand Jim, W6PQL is now offering 902 amp pallets. So QRO power on the 33cm band is no longer hard to generate.

So this is a group effort to get some western States on the air - have camper will travel*. 

* Once I won't freeze my butt off - we've seen -40 degrees Fahrenheit (-40 C)   here in Bozeman this winter!

My Annual Trek to 6M EME Mecca

September 5, 2023

It's not everyday that somebody gives you the keys to their ne-plus-ultra 6M EME station and says, "Have fun!". As Paul Harvey would say, "Here's the rest of the story".

Once a year Lance, W7GJ goes off to a rare place, usually an exotic island, to do 6M moonbounce with a single long Yagi and a KW. This week he's on Rodrigues Island out in the Indian Ocean as 3B9GJ. Somebody has to go to his Stateside QTH and put the W7GJ home station on. Teacher, teacher pick me!

 You need to understand Lance's home setup is a monster 4x 50 foot (15.25M) Yagis array and 1.5 KW - about as good as a 6M EME system gets. So each year Lance goes half way around the world and I go 3.5 hours west on the Interstate to Frenchtown. Thankfully, Lance gives me a 20 page check list so I can get the station up and running correctly.

This year was extra spicy as our mutual moon window to make the contact was exactly 55 minutes. Faraday rotation be damned! At least we both had ground gain - DXpedition Lance was enjoying a a moonrise over salt water, while his home station was racing moonset. We nailed it! I started seeing his signal when his moon was +0.5 degrees. Lance's portable station was a solid -20 during the four minutes the contact took using Q65-A and pile-up mode.

I've been doing this annual pilgrimage for about 10 years and I'm proud to say that I've been able to maintain a perfect batting average ... so far.

6 Meter Perseid Meteor Shower Outing DN54/DN64, Wyoming

 August 11/13 2023

Sunrise DN64bu @ 9,350 feet. Duncum Peak to the north.

GEAR: IC-7300, 600W LDMOS amp, 4el. LFA 6M Yagi, WSJT-X.  2.2KW Honda generator

August 11/12 from DN54 - Joyce and I squeezed into Horseshoe Bend Campground above Big Horn Lake. Not the best horizon, plenty of 6 meter QRN from RV charge converters, and a bit before the Perseid peak, but 30 folks logged, and a few 1200 mile contacts made. All meteors, no Es to be found.

August 12/13 from DN64 - We explored the top of the Big Horn Range and using the truck's 4x4 took the Sheep Mountain Road to a fantastic site well above tree line. The Perseid peak was the best I've ever experienced! Despite a frontal passage in the middle of the night that saw some 40 mph wind gusts, I logged an amazing 90 meteor scatter contacts. WA5TKU nudged his FFMA count to 480 grids and K5ND now has 483. Best contact was with WB8ART in Ohio at 1251 miles because we worked so hard for it.

LoTW upload done.

Western Dakotas 6 Meter Ramble

Dates:
June 13/14, 2023 - DN87 North Dakota
June 15 -  DN86 North Dakota
June 16/17 - DN85 South Dakota

Gear:
IC7300, KW amp, 4 element LFA Yagi.

Modes:
FT8/MSK144/Q65

Internet:
DN87/DN86 for sure, DN85 maybe. 
Slack VHF Chat - rover-rare grid area.

This was a camping trip with the pickup camper to the great American prairie to activate a few grids before it got too hot.

The trip was a success despite conditions not being the best - double-hop Es was quite limited. However, N3SL and W0JW completed FFMA with their contact to DN87 (Grassy Butte, ND). That made the whole trip well worth the trek east! 

In total 500 folks were worked via a combination of FT8/Q65/MSK144 modes.  

My rebuilt 6M KW amp refused to fire off so it was 100 watts only. I had inadvertently over-driven the amp during last summer's outing, and replaced the MRF1K50N device. However, I never got around to bench testing the amp. Murphy heard about my laziness and promptly showed up. It turns out the amp was fine! The 48 VDC power supply was the same one I used hard for the 23cm EME DXpedition to Curacao, and the tips of the blade fuses had burned off in the cheap Chinese fuse holder opening the 48 vdc line to the amp. All this was sorted out after the trip of course. A great lesson learned about getting too casual about these outings!

Murphy says, "Gotcha!"

Curacao 23cm EME Dxpedition (PJ2T)

 

Dates: February 8 - 13, 2023
Call: PJ2T - always 1st sequence
Location: Curacao (FK52)
Frequency: 1296.090 Mhz
Modes: Q65-60C CFOM preferred, can do CW after I work digital stations
Gear: W2HRO folding 1.8M dish, WD5AGO pre-amp, 350 watts @ feed
Internet: Yes, will be on HB9Q Logger.  
QSL Info: LoTW update after each session. W3HNK is the paper QSL manager for PJ2T

Donors that helped with luggage costs: JA6AHB, PA3FXB
A custom photo QSL card was sent to each station worked to commemorate the first 23cm EME ops from Curacao.

February 8, 2023 - Even with tight flight connections along the way we arrived in Curacao and the checked luggage with the amp was there waiting for us. It took awhile to cobble together a tripod and mount that would be up to the wind. It was clear at first RF that the station was not right. I thought the high wind was deflecting the dish enough to drop the gain - but my TX was down at least 10 db, so that was a clue to look elsewhere.
 
Never-the-less we pressed on. It was the middle of a week night in Europe so activity was down some. Fourteen stations were logged over four hours, most for a new DXCC. Logged: OK1KIR (-15), UA3PTW (-20), OK1DFC (-18), G4CCH (-20), ON4AOI (-24), RA4HL (-19), PA9RX (-22), RD4D (-19), W2HRO (-28), PA3FXB (-25), KD5FZX (-14), OH2DG (-15), PA3DZL (-20), YO2LAM (-22). Heard quite well - IQ2DB, K2UYH, W5AFY, W7JW.

Brett, PJ2BR was my co-pilot this first evening, he picked up several operating tips. His home 23cm station is about 80% complete.

February 9, 2023 Clearly things here are still not right, but I now have 21 stations logged. Tonight's catch SM6CKU (-19), ES3RF (-21), SM5DGX (-15), OK2DL (-18), HB9Q (-12), DF3RU (-20), K2UYH (-19).
Heard: NC1I, OK1IL, IK3COJ, PA0BAT, KB2SA, W7JW.

Great News! Your knuckle-headed dxpeditioner assembled the hybrid to the patch feed upside down and reversed the circularity. Kudos to Paul, W2HRO for looking at the picture I send and seeing the issue in 15 seconds. I had disassembled the feed for transport to Curacao and I did not realize how it needs to all go back together on re-assembly. The plastic mount for the hybrid is on the lower half of the patch feed if the patch feed shell is orientated correctly- it matters. We party at my moon rise tonight!
 
February 10, 2023 It was a great moon pass with a fully functioning station. I worked every station that I saw with a two hour nap in the middle when the moon went above my ability to elevate. A quick tropical rain shower found me working stations while tucked under a tarp trying to keep the gear dry. After a sleep period I got back on for the setting moon and added three folks - VK2JDS went into the log at 0.5 degrees elevation.  
      
Twenty-two folks worked in this session for a total of 43 stations. High winds are forecast for the next few days with rain showers so it might be a while before I can try more EME. I've disassembled the station for now to protect the gear.
 
Worked were: OK1IL (-23), SP5GDM (-25), DG5CST (-16), IK3COJ (-23), PA0BAT (-21), IQ2DB (-22), YO2LAM (-23), ZS6JON (-25), SP7EXY (-26), DK3WG (-25), W5AFY (-24), DL8FBD (-26), PA0PLY (-28), ZS4TX (-23), N1AV (-23), KB2SA (-24), VE6TA (-23), W7JW (-24), N5BF (-25), JA6AHB (-25), K5DOG (-23), VK2JDS (-25).

February 13, 2023 - It was well worth it to set up for one last session. Between rain showers I worked G4CCH (-23) and stronger later on CW (419), DL7UDA (-26), YO2LAM (-24), DG0FE (-23), NC1I (-16), IK2DDR (-22), W5GLD (-26), and K7EME (-27). That brought the total of stations worked to 51. I'm well pleased with the result.

Kudos to W2HRO - not only have I used three versions of his folding dishes (1.6M, 1.8M, 2.4M) now, but his product support has been first class the whole way. His dishes make these portable forays a treat!
 
Also a big thank you to Brett, PJ2BR for letting me commandeer his 1.8m dish for this operation. Also a tip of the cap to K8ND for keeping my log updated to LoTW.  W3HNK will handle paper QSL card requests.

Behold the correct orientation of the hybrid device.

Moon Tracking Automation Project

 

It's alive! Test bench setup with the Sub-Lunar SL-1 unit tracking the rising sun using PSTrotator software.
 
    For the last few years and eight State 23cm EME activations I've been keeping the 2.4M dish on the moon manually. This works pretty well if I remember to run out every 10 minutes to re-aim, and I have a visual moon. It certainly is simple, but a 2.4M dish's beamwidth  is pushing the limit of manual aiming on 23cm. 

    With the ARRL EME contest in a few weeks and a Montana winter coming on it is finally time to embrace auto-tracking. A slew drive system was a bit beyond my budget, but Paul, W2HRO has just developed a tracking unit that I could afford. The Sub-Lunar SL-1 looks to be just the ticket to cut my workload down and keep my toes toasty warm while operating from the barn this winter. 

    My solution was to start with PSTRotator software running on my laptop to calculate the moon or sun position, and then talk to the Green Heron RT-21azel controller through two USB ports, the Green Heron RT-21azel  runs the motors on the SL-1 rotor system, counts the pulses from both the azimuth and elevation encoders to calculate the dish's position, and reports back to the program where the dish is pointing. As you can tell basically the challenge was to integrate and debug three separate systems.

    The Blue Heron Engineering RT-21azel  controller is adaptable to so many different types of rotors it took a while to figure out how to teach it the specifics of both axis of the SL-1 rotor unit. The biggest key to success was telling Green Heron Engineering to configure the unit as a SPID rotor before shipping, then I could make a few modifications to the settings from there using the RT-21 Utility software to properly fine tune the SL-1 rotor unit. This ensured the unit came with the jumpers properly placed inside the tightly packed chassis.

    I really like that you can reduce the size of the PSTRotator's screen once you're comfortable that everything is working well. Nice to save some laptop screen space.  

The all important "STOP" button is still there.

    Long story short - after about eight hours of set up, some step-by-step debugging, and then cable building all the units play together nicely. When the moon gets a bit more declination I'll move things out to the barn and try a few contacts.

Hands on test: I spend about 12 hours on the moon during the ARRL EME contest the weekend of October 15/16 and the automatic tracking allowed me to work 56 stations on 23cm. A very good result for a 2.4M dish, around 300 watts at the feed, and near apogee. What a pleasure to just be on the moon come clouds or open skies!

The SL-1 kept me on the moon the whole weekend.

 RESULTS
1452 contacts from six Wyoming grids were made at the height of Es Season. LoTW upload done.

DN44
- June 16 Yellowstone Park was closed due to flooding so our visit was not going to happen.

DN43 - June 17/18 Kelly, WY This grid turned out to be a dry hole! The band never did crack open. I worked N7NW and seven Arizona stations on FT8 'tis all. 

DN52 - June 19/20/21 Fremont Lake, WY. I operated from this grid in three different places looking for the best open terrain to the south and east. No double-hop occurred while here, but 265 contacts were made. A decent result. Working N5OMG left him with nine grids to go for FFMA. 

DN42 - June 22/23 We'll arrive mid-day and get set up on Fontenelle Reservoir. So far 121 contacts on a nice combination of Es double-hop, meteor scatter, and even Q65 scatter out to 800 miles. Very happy to work K4PI for his FFMA #486. More double-hop on the 23rd to bring the total worked to 300 contacts, and get K8SIX to FFMA #480, Al picked up three grids during this opening.

DN51 - June 24.  Breaking camp this morning and heading south to some BLM dispersed camping just above Green River, WY - the land of wild horses.  This will be a one day stop. There was double hop to Florida as soon as I turned the rig on. I can tell DN51 is not in demand as much as DN42. Lots of double hops all afternoon and evening SE and single hop to the west coast at times. 158 contacts so far.

DN73 - June 27/28  We're 25 miles north of Bill, WY. Two great days of double hop, single hop both east and west, and some scatter out to 770 miles using Q65.  325  stations logged, best DX was EA8DBM!. This spot is the highest perch for 20 miles in any direction. Having cell service was an unexpected bonus.  Rapid and sustained QSB meant it took a while, but W9XX was logged for his FFMA #484. N5DG popped in for his FFMA #480. It was quite hot here, and given that I worked a bunch,  we bugged-out after some meteor scatter late morning of the 28th and used the heat of the day to travel to DN63 with the a/c on full tilt

DN63 - June 28/29/30 We set up west of Kaycee, WY now at 6,000 feet in the foothills of the Big Horn Mountains. We arrived late afternoon, stuck up the Yagi and proceeded to work 125 station to well after sunset. More double-hop up and down the east coast and single hop throughout the Midwest. Some deep QSB to make it a challenge but on peaks we completed with W3CP to nudge him to #479 FFMA and best of all logged N3XX leaving him to work only two more grids to complete his FFMA award. Can one hope for more tomorrow? June 29 - Several nice Q65-30A contacts this morning out to 1100 miles. Then double hop east, single hop west, and in the evening lots of Texas stations in to push the total to 300+ contacts from DN63. Some ops in the morning, then pack it up and bounce back down the road. June 30 morning brought double hop to New England and I passed 400 contacts from this grid - a personal best. Also worked EA8DBM from this grid, the second time on this trip. XE2AT and I completed a 1500 mile Q65 contact over about 30 minutes. What a way to finish out our Wyoming grid ramble.

DN51 near the Oregon Trail - all sky and sage brush.

DN42 - Sage Brush and Fontenelle Reservoir late evening.

70CM EME Montana (DN45)

 

Spring time in the Rocky Mountains. 9wl 70cm Yagi.

Over the weekend of May 6-8, 2022 I decided to put 70cm on EME as several folks needed Montana for their Worked All States award quest. The station was a single 9wl Yagi, 500 watts from a LDMOS SSPA, a very fine WD5AGO pre-amp, and an IC-9700 with GPS injection - a pretty small station for moonbounce. The weather started out with severe clear, but then the winds came followed by heavy wet snow. No matter, 25 stations were worked including one on CW. I hope this operation demonstrates that even a small station can be quite successful using Q65-60B mode on 70cm EME. Yes - I did tip the Yagi over and clear the snow off before operating!

A small RV makes for tight quarters, but everything has a place.

 The relay repair held up fine with the first 500 watt smoke test, and I had a very nice evening session on 70cm from here in Colorado (DM57oj) to finish up this trip's EME operating. I very much appreciate the folks in Europe crawling out of a warm bed in the middle of the night to give me a contact. The trip was a great success, and several folks added a State or two to their Worked All States quest. LoTW is up to date.
 
Worked: DG5CST (-13), PA5Y (-15), DK3WG (-15), ES3RF (-22), UA3PTW (-12), DL7APV (-5), NC1I (-11), OK1VUM (-17), ZS4TX (-22), OT7K (-18), OK1KIR (-15), SM7THS (-15), W2HRO (-22), K5DOG (-23), W5LUA (-15), DL1VPL (-19), W7MEM (-16), W7JW (-25). On CW I managed DL9KR (549), OK1KIR (419), DG5CST (429).
 
April 14, 2022
Last time I took the 70CM station apart I managed to twist the N connector loose form the body of the power relay in the pre-amp switching box and in the process bend the wiper arm. This morning with a full cup of coffee I managed to get things right and re-assemble the relay. We'll give 70CM EME a go from this lovely camping spot. 
 
Some creative bending of the actuator arm needed.

 
Relay repaired and back in its rightful place.



Easy to like this campsite. I flew the drone this morning as my reward for being Mr. Fixit.

Ute Mountain from the cliff top site. The ropes are extra wind anchoring insurance.
 
We'll gave 23cm EME a try today from Colorado. We found a great site at DM57oj on a cliff edge with Ute Mountain out there on the southern horizon. Setting up for a 2300z moonrise was easy, and the Internet connection was solid. Talk about having it all.
 
The site had no soil, it was all sandstone, so I laid my tent stakes horizontally, looped the tie-down strap around them, and put about 200 pounds of rocks on top. I also ran 2 lines upwind to make sure the gusts wouldn't topple the dish. Toward sunset the wind totally died as expected. 
 
A great session - plenty of folks worked on Q65-60C. NC1I (-18), OK1KIR (-16), G4CCH (-18), IQ2DB (-20), IK1FJI (-16), SM5DGX (-14), OT7K (-23), PA3DZL (-17), DK3WG (-24), N1AV (-23), K5DOG (-22), WA3RGQ (-24), OK1IL (-22), UA3PTW (-14), W5LUA (-19), AA4MD (-24), K6VHF (-28), FG8OJ (-33), XE1XA (-21), W5AFY (-23), G4YTL (-27), W2HRO (-23), KB2SA (-24), CX2SC (-25), KA1GT (-22), N0CTR (-20), W5LUA (-14), N5BF (-24)
 
Bonus - We stopped and hiked the trail at Sand Canyon Pueblo a few miles back down the Forest Service Road. Interesting to see the ruins of a site that was inhabited around 1250 A.D. by several hundred folks.

April 12, 2022
April snow SW Colorado. Given extreme drought this is a very good thing.

 
The gate on the road to the Forest Service site I was going to use for the 23cm EME ops was closed and locked. How rude! We booked into an RV park down the road to re-group and wait out the storm. And a fine storm it is! It looks like April 16 or 17th before we can try another Colorado spot.

April 10, 2022

DM57ae - Utah. Looking way down at the San Juan River.

 Joyce and I decided to give Goosenecks State Park a visit, so we headed south for about 30 minutes, arrived, and set up the 70cm station easily. Even though it clouded over just before moonrise I was able to complete with 14 stations. We had to walk a whole 100 feet (30M) over to the edge to see the San Juan River meander 1,000 feet (320M) below us. 
 
Worked using Q65-60B: DL7APV ( -5), DL1VPL (-23), DG5CST (-15), OK1DFC (-22), PA5Y (-19), UA3PTW (-19), OK1KIR (-19), PA2V (-19), PA2CHR (-27), OK1VUM (-19), DL8FBD (-25), DK4RC (-19), OT7K (-21). DL9KR sure knows where to place his CW signal to get my attention - we completed effortlessly 539/559.

A nasty storm is going to hit the whole western part of the USA - we'll see how we fare in Colorado on 23cm tomorrow.

April 8, 2022

DM57cg, Valley of the Gods, Utah 2.4M dish ready to go.

 It was a perfect day for 23cm EME. We found a dandy spot well off the road in the Valley of the Gods and set up easily. No wind, visible moon, and Murphy was missing in action. I worked all I heard! 24 stations were logged, all with good signals. Things really died off in three hours, so after another hour of CQ'ing to a quiet band I stopped and went for a hike. Later I got the drone out and shot this video.

In the log via Q65-60C: NC1I (-12), DG5CST (-8), UA3PTW (-11), DL4DTU (-16), OK1DFC (-19), IQ2DB (-22), HB9Q (-9), DK3WG (-25), N1AV (-27), OK1CA (-11), PA3FXB (-23), ES3RF (-17), DL8FBD (-22), G4CCH (-16), IK1FJI (-16), DK4RC (-12), OK1IL (-23), VE4MA (-21), DL7UDA (-20), W5AFY (-20), ON4AOI (-23), DG0FE (-22), W2HRO (-22), RA4HL (-15).

The next morning before the big winds arrived I shot a sunrise video to show you more of the Valley Of The Gods and  here also.

DM58cv Near Green River, Utah on BLM land

 A challenging, but fun day. We drove the 150 miles down from Provo and was QRV only 5 minutes late at 1805z. On 70cm Q65-60B EME I worked OK1KIR (-18), NC1I (-10), DL1VPL (-23), ES3RF (-24), UA3PTW (-12), DL7APV (-11), SM7THS (-20), HB9Q (-11), ON4AOI (-22), W2HRO (-22), DL5FN (-19), PA2V (-17), W5LUA (-17), and G4YTL (-20). On CW it was a pleasure to work DL9KR with 559 exchanged both ways - we hit it just right!. LoTW upload done.
    Murphy tried his best today. The amp suddenly died - when I opened it up the little piece of Teflon coax that serves as a capacitor in the output section was rattling around in the bottom of the amp. The heat had melted the solder! My bad - I usually do put a small fan inside the amp, but I didn't add it to the 70cm unit. I will. Long story short - I soldered the coax back in place and got back on the air.
 
Back in place you go!


Singular purpose 222 MHz EME Outing

 November 10, 2021
I rolled the 75 miles down to Yellowstone Park, Wyoming (DN44lw) and gave Dave, K1WHS his State #47 on 1.25M band. It all went according to plan, except for 20 minutes when the amp quit working - it turned out to be a dirty BNC connector. K1OR was also worked. Here are a few shots to suggest just how much fun it was, and what a lovely day I had for mid-November. Post Script: The following week K1WHS easily worked Kansas and Colorado to push  him to 49 States. It turns out Dave still needs Oklahoma to complete his W.A.S. quest.

Back seat station - note to self: Don't slam on the brakes.

Pretty organized, antenna on the top rack.

Tourist free!

The moon is there if you squint, and so was K1WHS.

Rural 23cm EME

 October 31, 2021

My DN45 low noise location with mains power.

Heat, coffee, a spare pre-amp, and 23cm EME.

 Late October was very good for working new stations. Seven new folks were added to the log bringing my home total to #81 on 23cm EME in almost a year of activity. New stations worked via Q65-60C: YO2LAM (-20), DK5AI (-24), IQ2DB (-18), DJ2DY (-21), IK7EZN (-24), DL1SUZ (-24), and W2LPL (-29).

    This is primarily a trip to get G3LTF his State #49 on 70cm CW EME before the weather goes downhill, but of course I'll put 23cm EME on too. Our first night on the road we'll be stopping in Wyoming (DN74) at Keyhole State Park. We have a camp site reserved with mains power!

The September 30 Wyoming 23cm EME stop was a great success.
Worked on Q65-60C were HB9Q (-18) who remoted in from SV5, OK1KIR (-13), SM6CKU (-13), OH2DG (-13), G4CCH (-15), UA3PTW (-11), UA9FAD (-22), DK3WG (-20), ES3RF (-16), DL8FBD (-21), F1RJ (-23), IK2DDR (-18), DF2VJ (-24), LA3EQ (-24), W2HRO (-22), DJ2DY (-23), ON4AOI (-22), NC1I (-13), PA0BAT (-20), N6NU (-26), SP5GDM (-21), KB2SA (-21), K5DOG (-17) and OK1DFC (-23). On the legacy JT65c mode logged were IK1FJI (-15), SM5DGX (-12) and GM0PJD (-30). CW was hard work tonight, but rewarding with OK1KIR (319), G4CCH (329), SM6CKU (319), G3LTF (429), and SM2CEW (419) all logged. 32 contacts made for a great evening's operation.

Wyoming (DN74) - Night Patrol @ O'Dark 30.


October 1st - On to Nebraska (DN82) and some 70cm EME operations.
On CW DL9KR (429) and DL7APV (539) were easily worked as the moon cleared a low line of trees. Switching to JT65b netted NC1I (-21), PA5Y (-24), DK3WG (-14), UA3PTW (-9), ON4AOI (-20), OH2DG (-19), OK1KIR (-28), G4FUF (-26), G4EZP (-26), DF3RU (-15). G3LTF had rain and very high winds that keep buffeting his dish around as he attempted to track the moon, as much as we tried over several hours we did not complete.

Nebraska (DN82) at historic Fort Robinson. 70cm station ready.

October 2 - 23cm EME from DN82 Nebraska.
A fantastic session with 40 contacts, four being CW. A very nice visible moon and no wind again tonight made for perfect conditions. I very much appreciate the activity. Logged on Q65-60c: DG5CST (-9), OK1KIR (-10), PA3FXB (-23), ES3RF (-18), IK2DDR (-21), DL8FBD (-22), DG0FE (-23), UA3PTW (-12), OK1IL (-18), DK3WG (-18), G4CCH (-15), I1NDP (-10), UA9FAD (-23), DL7UDA (-18), N1AV (-19), PA3CSG (-17), ON4AOI (-20), PE1CHQ (-16), DJ2DY (-23), DF2VJ (-23), RX6AIA (-26), PA0BAT (-16), K5DOG (-16), SM5DGX (-9), SM6CKU (-16), IK1FJI (-19), W2HRO (-20), LZ4OC (-27), W3CJK (-21), PA3DZL (-18), KB2SA (-21), F1RJ (-22), DF3RU (-14), I7FNW (-22), W1PV (-23), N5BF (-22). On CW OK1KIR (429), G4CCH (419), SM5DGX (419), DG5CST (539!) were worked without drama.

    Another fun trip to the Beartooth Plateau. We had high winds the whole time, and we bugged out a day early because the 9,700' altitude started getting to us - just another side effect of breathing forest fire smoke all summer. No matter - I worked most all I heard. Two highlights: W5ZN and I made it without stress for a 1150 mile meteor scatter contact for Joel's State #45, and WA4NJP was an easy EME contact for his State #48.

 222 MHz Meteor scatter contacts
W0VTT, W5ZN, N0LWF, W5AFY, KB7ME, AA5C, W9RM, and K7ND.

222 MHz EME contacts:
WA4NJP, N9HF (State #42) , N0AKC, and K1OR. W5ZN was heard well (best -18) for 45 minutes.

Now that is a 222 MHz Perseids ping!

Wyoming 70CM EME Afternoon (DN44lw)

 May 19, 2021

    Word on the street was that Peter, G3LTF needed Wyoming on 70cm CW EME for State #49. Who doesn't like a challenge? I threw the gear into the truck, headed south, and spent a lovely spring afternoon working all I could hear on "Charlie Whiskey" from my favorite Yellowstone Park spot. Logged: G3LTF (419), DL7APV (529), DL9KR (529), OH2DG (429), SM2CEW (419), DG5CST (529), UA3PTW (419), KL6M (419).

    KL6M made a neat recording of my CW signal with his 30 foot (9.2M) dish. Click here.

    Switching to JT656b added ON4AOI (-18), W2HRO (-20), DL8FBD (-22). Not a bad outing for a single 9wl Yagi and 500 watts.

Spring time in the Rockies. 9wl Yagi and 500 watts

Looking down has its rewards too.

Home ground! After 54 days on the road it is good to be back in Big Sky Country.

April 23, 2021 - EM77el - Mount Sherman, Kentucky
   
The six State 23cm EME activation is done. We drove up to Craig, N8DJB's place in light rain. The skies cleared a bit for set-up, and even went blue with a visual moon for most of the actual operating session. The Q65-30B experiment was a great success, in 1.5 hours I worked 27 stations. Logged were SM5GGC (-23), IK1FJI (-17), HB9Q (-3), OK1KIR (-11), PA0BAT (-18), G4CCH (-19), OK2DL (-9), DG5CST (-10), OK1DFC (-20), PA3DZL (-15), DK3WG (-23), DF4RC (-11), ES3RF (-21), SM6CKU (-11), DL8FBD (-21), OK1IL(-20), G4YTL (-22), UA9FAD (-24), IK7EZN (-22), SM5DGX (-13), PE1LWT (-20), OM4XA (-20), PA3FXB (-19), DL7UDA (-16), KA1GT (-21), DG0FE (-19), K2UYH (-17). 

JT65c produced as well - contact was made with NC1I (-9), ON4AOI (-12), IK1FJI (-13), K2UYH (-11), VE4MA (-18), VE3KRP (-19), DF2GB (-19), GM0PJD (-25), K5DOG (-17), CX2SC (-25), KN0WS (-20), N1AV (-19), PE1CHQ (-18), PA3FXB (-18), N5BF (-25), DL3EBJ (-12), W2HRO (-20).

There was time for CW also, conditions were excellent and I worked HB9Q (539), OK1KIR (529), G4CCH (519), IK1FJI (419), K2UYH (419). Altogether 45 individual stations were worked. LoTW up to date, including all Q65 contacts.

April 22, 2021 - EM64kq Wheeler Lake, Alabama
A perfect day to finish up the Alabama stay - a near full moon, no wind, and 70 degrees. I worked several additional folks to bump the total of stations worked to 53. On JT65C I worked UA3PTW (-20), ON4QQ (-21), DL3EBJ (-17), IK3COJ (-23), PE1LWT (-24), LA3EQ (-28), OK2DL (-8), DG5CST (-9), SM4GGC (-24), I5YDI (-25), VE3KRP (-23), IK7EZN (-27), DK3WG (-28), LA1TN (-23). CW signals were quite good today, worked were K4QF (419 on scatter), DK3WG (329), DG5CST (529), HB9Q (529), OK1KIR (419), G4CCH (519), and IK1FJI (329).
    On to Kentucky tomorrow before the rain arrives, and then to drop all this gear off at a pawn shop - Ok, maybe not. :-)

April 21, 2021 - EM64kq Wheeler Lake, Alabama
   
A very pleasant 200 mile ride up into Alabama on back roads this morning. Set-up went well and the moon was just clearing the only tree at our campsite when I started calling CQ. It was another flawless afternoon of operating 23cm EME with 39 stations logged.
    The big news was completing an easy contact with K2UYH for his State #50. He is just the third person to earn Worked All States on 23cm behind W5LUA, and K5JL. Congratulations Al!

    Ben, K4QF stopped by for a visit and he seemed to enjoy the show! 
 

    In the log: DL7UDA (-18), PE1CHQ (-17), HB9Q (-5), DF3RU (-15), SM6CKU (-17), OK1KIR (-12), OK1IL (-21), ON5GS (-21), G4CCH (-16), OK1DFC (-22), DG0FE (-21), PA3DZL (-18), DL8FBD (-25), ON4AOI (-23), K2UYH (-17), IK1FJI (-20), UA9FAD (-26), NC1I (-12), ES3RF (-24), K5DOG (-18), PA0BAT (-20), PA3FXB (-24), DF2GB (-18), G4DDK (-25), OM4XA (-21), W2HRO (-20), G4YTL (-23), N5BF (-24), VE4MA (-21), KA1GT (-21), W5LUA (-11), SM5DGX (-10), DF2VJ (-26), RN6MA (-26), KB2SA (-24), N1AV (-19), AA6I (-19), KD5FZX (-10).

 April 20, 2021 - EM53cu Grenada Lake, Mississippi
   
Today I got on at moonrise for three hours, and worked a final few folks. DG5CST was an easy CW contact at RST 519. On JT65c worked were PA3DZL (-16), DG0FE (-18), I7FNW (-18), RN6MA (-25), PE1CHQ (-16), UA9FEM (-24), and G4DDK (-25).
    This made 51 unique stations worked, many on more than one mode, for the Mississippi stop. How nice is that!? All the gear is packed and in the morning it's another 200 mile jaunt up to Alabama. 

Rub-a-dub-dub, an amplifier in a tub.

 

April 19, 2021 - EM53cu Grenada Lake, Mississippi
    I moved the dish to a better spot this morning, and swapped out the 12 year old LMR-600 feed line. The changes seemed to restore my signal nicely. Let's report those worked today by mode. On CW it was OK1KIR (529), G4CCH (529), SM6CKU (419), HB9Q (549), IK1FJI (429).
    On Q65-30B I worked 14 stations in 55 minutes as well as several others. Logged with the new mode were OK1CA (-16), OK1KIR (-16), PE1LWT (-26), IK3COJ (-21), ES3RF (-22), AA4MD (-20), DK3WG (-26), G4YTL (-23), DL7UDA (-20), PA0BAT (-17), DG0FE (-25), UA9FA (-23), KA1GT (-22), IK1FJI (-18), G4DDK (-28).
    JT65c produced also with the following folks logged: UA3PTW (-13), IK1FJI (-15), UA9FAD (-30), I5YDI (-21), PE1CHQ (-18), VE3KRP (-26), DF2GB (-20), ES3RF (-22), IK2MMB (-18), OM4XA (-22), RX6AIA (-26), DF2VJ (-25), KD5FZX (-9), ON4AOI (-28).
    I ran out of folks to work with plenty of moon left. 47 different stations have been worked from EM53 so far. I'll do a brief session tomorrow, then packing for Alabama.

April 18, 2021 - EM53cu Grenada Lake, Mississippi
   
A smooth 200 mile ride to MS, so I decided to throw the station together, and see who wanted to play 23cm EME. K2UYH nailed down State #49 on both CW and JT65c, and 19 others were worked - a great start to the Mississippi operation. We have a great camp site, and the weather looks to be perfect for the next few days.

In the log: DF3RU (-15), G4CCH (-14), SM6CKU (-22), DG5CST (-14), PA3FXB (-22), K2UYH (-16), N1AV (-21), SM4GGC (-23), W2HRO (-27), DL8FBD (-25), OK1IL (-21), HB9Q (-5), K5DOG (-22), DK4RC (-12), W5LUA (-23), OK1DFC (-23 Q65-60C), KD5FZX (-17 Q65-60C), VE4MA (-21 Q65 60C), K2UYH (CW), NC1I (-19), and KA1GT (-22 Q65-30B). LoTW up to date.

April 17, 2021 - EM45dh, Arkansas
   
Today was a CW special. The following guys were logged on "Charlie Whiskey": DG5CST, G4CCH, OK2DL, IK1FJI, DF3RU, and HB9Q. HB9Q was Q5 on SSB, but I didn't have enough signal for us to complete. SP5GDM (-27), and PE1CHQ (-15) were added on JT65c to bring the grand total to 62 contacts with 54 different stations. On to Mississippi!

April 16, 2021 - EM45dh, Arkansas
   
A big, big day of 23cm EME - Arkansas must be rare! I completed 52 contacts with 50 stations made under cloudy skies, and a few rain drops. K2UYH was worked for his 48th State. My aiming technique was up to the challenge today.

Logged: HB9Q (-16 thru trees), DG5CST (-15), OK1KIR (-16), UA3PTW (-18), NC1I (-17), OK2DL (-11), OK1CA (-8), OZ4MM (-13), DL7UDA (-16), DK4RC (-8), IK1FJI (-18), PA3DZL (-16), ES3RF (-24), DF3RU (-17), DL8FBD (-23), G4CCH (-14), PA3FXB (-21), UA9FAD (-25), DG0FE (-18), OK1IL (-18), UA9FA (-23), ON4QQ (-19), DK3WG (-26), N1AV (-18), W2HRO (-18), G4YTL (-25), OK1DFC (-21), CX2SC (-27), PA0BAT (-25), OM4XA (-25), SM4GGC (-18), ON4AOI (-17), RA4HL (-19), IK3COJ (-18), DF2VJ (-26), K2UYH (-11), OK1KIR (CW 429), W5LUA (-9), IK7EZN (-21), SM6CKU (-9), I5YDI (-23), AA4MD (-22), KD5FZX (-9), SM5DGX (-8), VE4MA (-20), G4DDK (-30), N5BF (-24), VE3KRP (-29), PA2DW (-23), GM0PJD (-29), K2UYH (CW 419), K5DOG (-20). LoTW upload done.

Pile-up fun!

 
Out of the wind and rain, and plenty of folks to work. Perfect!
 

April 15, 2021 - Arrived EM45dh, 23cm EME set up
    Joyce and I arrived early at W5ZN's place. Set up was error free, so I was QRV much sooner then expected. I put the time to good use working KA1GT (-27), and KB2SA (-27). It took a while to get my azimuth ring aligned, but things finally came together.

Fitting in at the W5ZN antenna farm. EM45dh

April 6/7, 2021 - Bonus - 6M ops from DM73aq, Carrizozo, NM
   
We stopped at Valley of Fires BLM campground to hike the lava trail. I stuck up the 6M Yagi and over two days worked 34 station on a combination of meteor scatter, and ionospheric scatter. It was a pleasure to knock off another FFMA grid for several folks. Best DX was a midday shot to W0VVT 1,110 miles north using Q65-30A. The new mode continues to impress!

DM73aq - A horizon any VHF operator would love to have at home.

March 29, 2021 SW of Silver City, NM (DM52sn)
   
A perfect EME evening with a full moon, perigee, no wind, and a cloudless sky. A special thanks to the EU folks who got out of bed to work me - much appreciated. Worked: OK1DFC (-23), VE3KRP (-24), PA3DZL (-14), DF3RU (-10), CX2SC (-19), OM4XA (-24), SP5GDM (-23). KB2SA (-25), and W2HRO (-22). That makes 34 contacts total for the New Mexico stop.

March 28, 2021 SW of Silver City, NM (DM52sn)
    We drove the camper about 145 miles east into New Mexico, and found a great spot up on the Continental Divide at 6,400 feet. Setting up went well, and when the moon cleared a few low trees we were off to the races. It was an excellent session with 25 stations worked on a combination of JT65C, Q65-30B, and CW. No JA/VK/ZL activity however. :-(

Logged: K5LA on ground wave 115 miles, DG5CST (-9), UA3PTW (-12), HB9Q (-1), OK1KIR (-5), ON4AOI (-17), N1AV (-17), ES3RF (-21), DL8FBD (-19), SM6CKU (-11), DK4RC (-7), OK1IL (-15), OM3XA (-21), PA3FXB (-17), SM5DGX (-16), VA6EME (-17), DK5YA (-22), DG5CST (CW 429), OK1KIR (CW 419), W2HRO (-27), K2UYH (-11), DF2VJ (-25), KA1GT (Q65-30B -19), PA0BAT (-21), K4EME (-25).

Nothing like a full moon at perigee. Coyotes were howling!

Moonbounce does have a certain aura about it.  :-)

Tight quarters, but it works if I get all the cables correct!

March 19 - DM23vs Quartzsite, Arizona
Sometimes you get the bear and sometimes the bear gets you! Today was one of those days where the bear almost won. The 2.4M dish by nature of its size and stiff fiberglass ribs is sometimes difficult to open. Pointing straight up for a gravity assist helps, but imagine my surprise when I couldn't budge it past a certain point. Finally, I pulled the fabric off four rib-tips and was able to get going. After a pleasant afternoon of working folks on 23cm in both JT65c and Q65 30C/60C modes I sprayed the fabric on the dish with water and it stretched enough to get me back to normal opening and closing ability. As a ?bonus? I did blow my best pre-amp up by tripping on the PTT cable and disconnecting it. Who knew Murphy is a desert dweller!  I must say Q65 is an impressive mode. Even with faster 30 second sequences I was working stations easily. All in all not a bad session for the moon being at apogee. The next day we had serious winds so no EME.

 Worked: OK1KIR (-10), DF3RU (-13), ES3RF (-24), OK1IL (-15), HB9Q (-3), N1AV (-24), KA1GT (-25), SM6CKU (-9), N1AV Q65 (-20), KA1GT Q65 (-25), and KB2SA Q65 (-26).



A long day knocking trouble back, but rewarding. Open air shack.
