@LA9XGA Thank you for roving and the new grid👍

[Joshua | DL3JOP @dl3jop]

@ibelings @mm9sql @rdavies6 @BorgersonS Wow! Do you have a simulated or measured radiation pattern of it?

[Joshua | DL3JOP @dl3jop]

@mm9sql @ibelings @rdavies6 @BorgersonS 💸
Would be cool to mount it on a car !

[Joshua | DL3JOP @dl3jop]

@W8LR_Jerry Tnx for the QSO! Booming signal on RS-44

[Joshua | DL3JOP @dl3jop]

Looking for a working panel/head unit of a FT-817. I got one on the workbench with multiple flaws (one of them being a dead MCU)
Maybe one of you has a broken 817 on the shelf ? 😊

Just worked #AA8CH in United States Of America 🇺🇸 (Gridsquare: EN74 / distance: 6549.5 km) on RS-44 🛰️ (4.5° el / 325.4° az) using SSB #hamr #wavelog #amsat

@ThePCBDesigner Aisler is correct😄.

Some sunday testing of a diy power probe for an #HP #437B power meter.
The next step is proper cabeling and testing and calibrating!

@iNT2000 I only did the easy part of mounting the PCB and connecting it to the existing hardware.

Jan, DO1FJN did the heavy-lifting by designing a complete drop-in board for the C5 using an AMBE codec:

Added D-STAR to my Siemens C5

While setting up my 432 MHz Tonna Yagi the dipole mount broke which we then fixed with duct tape. Now I printed a proper replacement part for it.

May I request a new award program? TotA - Tractors on the air. Or /TM as @CarstenGrn1 suggested.😝
We used my tractor to mount the antenna.

Find us as #DA0UDS in the DARC VHF/UHF/SHF Contest. The first proper contest of our uni group.

[Joshua | DL3JOP @dl3jop]

@glasbrenner @CarstenGrn1 Oh yes the former lead acid battery was huge! Luckily the 2000 has this cool battery tray which swings out. Makes swapping it a little easier.

@MarcoReps Some people collect ppm, some dBm 😝

[Joshua | DL3JOP @dl3jop]

@dh6kq Hi Andreas, ich habe mehrere Platinen für unsere Funkgruppe an der Uni gemacht. Sollten welche überbleiben melde ich mich bei dir.

Replaced the #Kathrein duplex filter in my modded #Siemens C5 with a PCB designed by #DL8SDL in 2001. I found his schematic, ported it to a modern PCB stackup and updated some components.
RX/TX isolation > 30 dB, PA/Ant < 0.7 dB loss😊

Just worked 5B4AOB(@M0GIW) in Cyprus 🇨🇾 (Gridsquare: KM64EV / distance: 2626.6 km) on RS-44 🛰️ (23.1° el / 166.4° az) using SSB

Thank you David for a new DXCC on LEO in a long time✌️

Finally finished my CRT to LCD conversion on my #HP #8594E spectrum analyzer. The LCD is a little larger and much brighter. Under the hood it uses a 5,6" LCD, GBS8200 video converter and an #esp8266 with gbs-control to convert the HP video signal.

The old CRT has quite some burn-in😄
