Classic signs of RFI, how did you verify your antennas?

?Hi all,

Finally, I have finsihed to build my QDX.

RX works perfectly on 40m & 20m. I can see decoding frame in WSJT-X, no problem with RX, good!
Now TX
Symptoms: WSJT-X transmit one or two sec and switch back to RX.

Tests I did:
I have tested it with the serial console test tool and I am facing following issue:
- PTT test works
- Transmit test works with coax + dummy load.
- Transmit test DOES NOT work with coax (same as previous) + any of my antenna (Dip?le or EndFed DIY and JPC 12). Putty (console terminal) show me an error after one or two sec. QRP is still here but in a lost state where putty can't really interract with anymore.

I have verified my antennas and they are OK (I used them often in SOTA).

Any help is welcome. Thank you all.
