#introductions Hi, i'm Milosz, from SP. I have a loooong (25y.) break and reactivate licence last month. I'm present on #fediverse already, but decided to keep hamradio topics on separate account. Interested in #sstv #fax #digimodes, #qrp, #diy projects, i would like to try #ballons / #hab . Committed to #foss, openhardware and #soc programming.

At sunset in the forest near the house: Testing a new antenna inv. V on 20m: I managed to tune the length/height/tilt so as to obtain resonance at approx. 14.200 Mhz and good SWR without an antenna tuner (which I do not have for the time being).
TRX powered from 3S/2200mAh li-po battery.

To do tomorrow:
- solder power cable (from car lighter socket + li-pol battery) for the new #ic705
- make an inverted V antenna on 20m

Once upon a time, when there was no internet, in order to build an interface to #fax, you had to receive a scheme using... fax 😆 . Beginning of the 90s, received on 80m from SP9AMH, I think with a program on a C128 (for a short time I already had an #Amiga and still a #C128) #history

While waiting for the possibility to federate git sites (development in progress: https://forgefriends.org/) in the meantime I mirror any interesting code (especially hamradio related) from other git sites (mostly github) on my gitea server: https://gitea.citizen4.eu/mirror

I am just scanning my huge library of paper electronic schematics from the 80-90's. Mainly #digimodes #fax #sstv related projects. Some unique, never published, only in my paper version. I will then upload everything somewhere on archive.org.

I'm just waiting for my new (after 25 years break) trx and this is my dilemma: whether to spend money on factory-made HF/VHF antennas (and go QRV faster :-) ) or spend the same money on a cheap antenna analyser and #diy. Years ago I made all the antennas myself...

I made my first trx in 1990 based on the description in "Radioelektronik" 1984/11 https://archive.org/details/Re0184OCR/Re_11_84_OCR/page/n9/mode/2up . #qrpp, single band 80m, ssb, simple phase-homodyne design. All blocks double used. Even the rx preamp. was at the same time the tx PA. #history #MyFirstTrx
