(tr)uSDX Forum

Hi I purchased a pre built unit from the official supplier on Ali Express. All good initially for two weeks but now I'm getting no output on any band and a warning sometimes comes up check ptt. When I press the ptt in cw mode the R on the display is not changing to T as it used to so I'm guessing it's not switching to transmit? The receive goes quiet and when ptt is released there is a slight delay and relay clicking? noise before receive audio comes back on. I have an external mic I have used for previous Qso on this radio so tried that but exactly the same. Receive is fine. Noticed as well in menu I can no longer select VOX on, just get the relay type clicking noise. Any ideas, is this a menu issue or something else? Thanks Gary
