Yaesu Ft-301

 

Good day
Im a new yaesu ft-301 user. I have a real head scratcher. My yaesu ft-301 works fine until you press the ptt key then its like it stays in tx mode and the sound output does not return to normal. If it does that you need to power down the radio and power it up agen. If anyone can give me a litil bit of inside why it does that it will be much appreciated.

Starting with the simple reasons first is the vox turned up a bit? Does it do it into a dummy load? Does it do it if the Power is turned right down.

Could be that the Tx/Rx relay is sticking in the transmit position. Removing power would reset it. The relay may need to be replaced. Or it possibly could be removed and the contacts burnished.

Check for any loose or broken wires or solder connections. Gene N4FZ

If the vox is not working, you can verify the ic mc14011. It's a trouble source.
