Problem on RX on all bands (5V on RX pin)?
Posted: 05 Dec 2022, 16:39
Hi,
First of all I'd like to congratulate for this project. I have assembled one but unfortunately I have a problems on the RX, I can only hear noise on all bands. Following various posts in the forum I send a signal on 80mt with a nanoVNA in the antenna, I can follow it trough the relay and the filter but after it I see 5V in the RF pin.
If I detach the main board and send the signal in it, I do not have the 5V on the RF pin and I can hear the tone. Is this 5V presence on RF pin ok?
TX seems to work nonetheless.
Thanks for any help.
