PA7JWC 🇳🇱 - 5Q7DX 🇩🇰 Jan-Willem

@SP3RNZ Okay, thanks for the info. I made the radials from flat aluminium strip. I’ll see tomorrow if it works with RG‑58 as well…. 😉

@PA7JWC My design is with measured and good quality two RG-58 pieces, then short piece of coax with 3 cores and N type socket. Still struggling with radials, but I think I will use 6mm pipes, they are cheap here.

The first steps of my new antenna project are done 🚀 Building a 70 cm Eggbeater antenna is underway! Can’t wait to run some tests on different satellites like RS‑44 and the ISS 🛰️😉 And honestly… building antennas is just too much fun 😄🔧 #amsat #hamradio

@SP3RNZ Your Eggbeater looks great as well…😉👍 For the phasing I’m still unsure about the design. I’ve used RG‑316 here, but I actually want to try it with RG‑58. Which one did you use, Greg?

@PA7JWC Hmm 😊 we need to share results. What coax for phasing ?

I want to make an overview for myself of how the Doppler effect works in satellite communications. In the meantime, I have created a one-page document with an explanation. I’d be happy to share it, so that others might find it useful as well… 😉💪👍 #hamradio #amsat

@F5rrsD Interesting... I'm following this thread with interest... own design Damien ?

New project: Antenna Polarization Switch Controller for M5Stack Core2! Safely remote-control RCH/LCH/Horizontal/Vertical modes for satellite ops. TX-detect (GPIO32) blocks switching during TX—no more fried relays! 🛰️ #HamRadio #M5Stack #AntennaSwitch #F5RRS

@SP3RNZ Also Merry Christmas for you and family Greg! I also most actively CW with PC26WWA 😉👍

@PA7JWC Merry Christmas Jan, CU on the air ! I will be mostly #CW op of SO3WWA 😉

In January I will be QRV as PC26WWA for the WWA Award. Together with several enthusiastic amateurs, we will be active with multiple special calls: PA26WWA, PF26WWA, PE26WWA, and PD26WWA. Hopefully we’ll work each other. Much success and good luck hunting! #hamradio

Preparations have started for our trip to Saeby, North Jutland (IOTA EU-171) 🇩🇰 From 17 to 23 sep, I’ll be active again as 5Q7DX, together with my friends Sven PA1SVM and Maarten PD2R / OV2T. We will be active on HF, satellites (RS-44, SO-50, QO100 etc.). #hamradio #AMSAT

@DL6AP @NmlS57 @G0IIQ @G_0ABI @F5rrsD @Santiag99239819 @flo_0_ @ea3ta_juan @9a6ww @be747 Thank you Andy 👍

Tnx for the Qs: @NmlS57 @G0IIQ @G_0ABI @PA7JWC @F5rrsD @Santiag99239819 @flo_0_ @ea3ta_juan @9a6ww @be747 and not sure abt @EA2Z4/p. Hope did not forget someone. 🛰

🛰 ES8/DL6AP on SO-50 ⏰ 2025-08-15 from 10:57Z to 11:10Z 🗺 KO28 📻 436.795↓ FM 📢 QTH: ESFF-0004 👀 hams.at/alerts/1cffdef…

@flo_0_ Kein Problem, Flo… falls du mal wieder in der Nähe von Breda bist, weißt du ja, dass du willkommen bist.. 😉👍

@PA7JWC Leider zu weit südlich für mich. Außerdem werde ich schon früher unterwegs sein.

Another SO-50 pass from JO22 🇳🇱 where I could not hear my downlink but obviously others could. Logged @EA1PA, @ea1dr, @iNT2000, @DL4KCA, G6UST and G0GTV. #amsat #hamradio

@flo_0_ @EA1PA @ea1dr @iNT2000 @DL4KCA Mehr Richtung Süden!! Die schönste Stadt der Niederlande 🤪🤣🤣

@PA7JWC @EA1PA @ea1dr @iNT2000 @DL4KCA Wo ist Breda? 😇

Tried working through SO-124, unfortunately it didn’t go well. It keeps running anyway… 🤣👍 #amsat

@DK9JC @ea1dr I’ll have to see if I can be active in a few more places. Kind of depends on the family, and whether dad’s allowed to bring his antenna and THD72 … 😄😉👍

@PA7JWC @ea1dr cool not long ago i worked from JO11TO and SO

Finally made it from holiday QTH JO11TN! Took a bit of fiddling, but managed to work two stations via SO-50. Thanks GB3RS and @EA1DR #amsat #hamr

@flo_0_ @1C_SO50 @DD1US @EA1PA @F4IOZ @DK9JC @G6YTZ Thanks for QSO.. 😉👍

High elevation pass of @1C_SO50 SO-50 over JM19. Worked: - @DD1US 🇩🇪 - EA2AA 🇪🇸 - @EA1PA /P - @F4IOZ 🇫🇷 - @DK9JC 🇩🇪 - @G6YTZ 🇬🇧 - @PA7JWC 🇳🇱 #amsat #hamradio

@pe0sat Ziet goed uit… 😉👍

Building an UHF Egg beater #amsat #cubesat #strf

@2m0sql @CarstenGrn1 Yeah, I know exactly what you mean, Peter! Those M2 antennas are amazing, but the price is just too high. I want them too, but my wallet says no 🤣👍 Of course, a hobby can cost money… but it still has to stay fun…😉

@PA7JWC @CarstenGrn1 Should see the M2 prices for their sat antennas.. I want them but the price makes me shudder

Built an LHCP/RHCP and horizontal/vertical polarization switch. This is the 2m version now time to build a 70cm one. 🤣Building it yourself is way more fun than buying a switch! 😉👍 #amsat #hamradio
