I have a yaesu ft-736r with no audio
It transmits, but no receive, are you sure, have you tried playing around with the volume control?
If, so did that make any crackling noise? If so, then this is due to lack of use of the volume control, many radios, including the old transistors with dials, would make crackling sounds when you adjusted the volume, and as I say, this is due to lack of use, So if this is the case and to get your receiving, turn the volume control up & down fully for a few minutes and while doing so your radio might receive a transmission that will be loud, quiet, loud, quiet, etc., as you play with the knob.
Keep doing so until all crackling has disapeared.
Do this often as possible when firing up your radio for the day, the more use these controls get, the better.
I hope this has answered your query.
