[Wouxun KG-805G GMRS Radio]

Update: I managed to get mine to work... Had to push real hard to get it to make connection in the jacks. Not sure whether the radio's jacks are the issue or the PC interface cable plugs are the issue...

 

Wow, I was having this problem as well, getting very frustrating. so I unplugged the cable from the radio, held the radio sideway and pushed the plug in evenly and heard it click. Now it works, I believe it getting the plug to properly seat.

 

Thanks for the info, saved me from pulling what little hair I have out.
