hello all, I have an uBITX v4, I didn't mount the microphone connector, and it's QRP. Interesting the option of installing a PA at the exit, as it is sometimes necessary to use it. Do not forget to us

Hello everyone, Grateful for the tips. I changed the five relays of the uBITX v4, it improved a lot, for example it stopped oscillating the power, even with "fake it" unchecked for "split" operation.

Group, Yes, uBITX has some problems, as it was developed to serve as economically as possible. That is why we are working and trying to improve. I am very grateful to the group for their help and atte

Olá Evan, Curt e grupo. O meu uBitx v4, voltou a oscilar no 40m, 7074kHz em FT8, mesmo com "fake It" selecionado no JTDX. E observo a falta de potência de RF de saída na faixa dos 10 a 15m. Em qua, 20

Olá todos, Tenho uBITX v4, seria um problema de alinhamento a falta de potência RF de 10 a 15m? Na frequência de 7074kHz a potência de saída oscila aproximadamente 5 W. Mesmo ativando "fake It" no JTD

Evan and Group How do the selections of relays KT1, KT2 and KT3, or TXA, TXB and TXC work in uBITX v4? How are frequency bands selected? 73's Rubens py2pvb

Evans, and group. Grateful for the help. I see in the diagram that TXA drives relay KT1, TXB the KT2 and TXC the KT3. For 10, 12 and 15m how should these relay combinations be? Do you tell me that 10m

Hi all, No Power Out in: 10m, 12m and 15m. Note: There was a power fluctuation problem in digital mode - JTDX (FT8), observed at 40m, with the help of the group, I checked the option "Fake It" (JTDX),

Hi, I'm cleaning up the stains on the garage floor right now. But, I will test in CW, really a good idea, thanks. 73's PY2PVB Rubens Em sex., 15 de jan. de 2021 às 11:02, Curt via groups.io <wb8yyy=ya

For all, I would like an opinion, I have uBITX v4, the RF power is oscillating, now with more intensity, as it is a QRP, I believe that a variation of 2 to 3 watts is not a good practice in the 40m (7

hello Rafael and group, As I said before, I use uBIX v4, and the radio enters RX just by feeding it with + 12Vdc, you can switch to TX: via VOX, CAT, PTT, CW woodpecker (manual) or Iambic A or B, etc

Rafael, good morning. You can select telegraph mode and select CW and close a wire (short circuit), for example. Set the tone to 1kHz, or another value. There is another way via the "PTT" button (norm

Hello everyone I have been using FT8, with 1kHz tone in "TUNE" with uBITX v4, via CAT, for alignment. -- 73's PY2PVB Em qui., 7 de jan. de 2021 às 17:44, Rafael Diniz <rafael@...> escreveu
