SBITX V2 - first time on the air
Вставка
- Опубліковано 23 жов 2024
- First time playing with SBITX V2 made by HF Signals on real antenna.
Listening on 20m band, CW to VU2TMP.
It looks like an interesting hybrid platform from tinker for tinkers.
Unlike other closed source and proprietary radios, the SBITX is entirely
open source, from its circuits to the software.
But ...it is a different beast!
RF gain: 50%
BW: 200Hz
AGC: Fast
Hi Petr. Thanks for helping me getting my sBitx V2 fixed and hopefully back on the air. 73
Petře, tak jsem se podíval na dostupné informace. Manuál zatím asi není, ale jinak to vypadá opravdu velmi zajímavě. Jaké máš s tím zkušenosti? Můžeš doporučit? Kolik činí poplatky mimo cenu? Zvažuji, že si hoobjednám. Za info předem díky Lev OK2PLL
Petře, docela zajímavý TRX, tedy hlavně provozní možnosti. Ty ho máš? Zajímajímne praktické zkušenosti. Lev OK2PLL
A very nice transceiver, it would be good to hear your comments Petr. 73 Will VK5WB
Will, it still needs extensive work on CW application, keying timing and switching with iambic paddle input. It is not ready for serious CW operation yet even with latest software rev. dated May 11th 2023…
ok mate how is the cw is the log book working will get mine thursday or friday ..jeff..
Well update 2-May-23 Farhan is testing new build version were should be fixed few issues including iambic keying and logging. Using external keyer works ok (straith key input must be set)
Hello Speed means too low 73
Would be nice to see and hear you using the key 😏
mine does not work well on cw and locked in tx burning the tx transistors plus one track ended up getting hot and solder mask burnt off so i tinned the track and put in new transistors.but still very poor cw i have no idea what do do..

Jeff so sorry to hear it. The iambic keying issue is under fix. Also the burning the finals sounds like issue with ALC and overdriving finals. It happened on few units and Farhan sent advisor to not TXing until he will not release fixing build. Update 2-May-23 he is testing on few unit the new build which should solve it. Please wait. Do not be annoyed, it will be fixed soon and you will enjoy your new beast. I believe. 73 Petr
@@petrok1rp254 Thank you for the information ☺️
I am using my unit with external keyer with iambic paddle and it works ok. Using RF drive set to only 40% for low power and not overdriving finals I worked VU, ZL, USA and PY on 20m. But I am recommending to stby for new build fixing these issues. Petr
You welcome Martin. I know it is a bit strange and annoying but Farhan is trying to do his best to fix these major issues. 😉
