#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
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...

Also posted this on the GQRP mailing list:
I compiled a list of all purchasable QRP transceivers I am aware of and added some information (supported bands/modes, power consumption etc.). I thought you might be interested in this, so I uploaded it here:
PDF: http://qrz.is/qrp_trx.pdf
ODS: http://qrz.is/qrp_trx.ods
I'm currently thinking about a more clever way of publishing. If you have any suggestions, error corrections or additional transceivers for the list, I'd be happy to fix or add them.
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
