Re: TX relay problem
toggle quoted messageShow quoted text
It is a common phenomena on ubitx. Some steps to avoid this
1. Replace the mic+ PTT wire with shielded cable. Good quality usb cable can be use.
2. Keep some distance between ubitx and Linier power amplifier.
3. Give earth connection to ubitx case and pa.
This problem will solve with the 1st point itself.
If the ubitx does not come back to receiver mode after transmitting, simply replace the Rx/Tx relay with a good quality relay just like O/E/N make.
