[CHIRP doesn't recognize my Btech V1]

I had a similar issue - and the cable I had had an issue up near where it connected to the radio. While it worked fine on a different baofeng radio - the housing caught just a bit on the lip of the recessed area where it plugged into the radio - and it did not allow the two plugs to quite seat all the way.

 

I shaved a tiny bit of plastic off the cable plug (not the radio), and once it seated properly it was ok.

 

I have no idea if this is your situation, but it sounds very similar.

 

Hope it helps.

I had this problem with the Btech PC03 programming cable when I used it with my Retevis RB26 GMRS.  We live in 2-story home and my two children live upstairs.  My wife or I had to yell pretty loud for them to hear us sometimes, so I purchase a 5-unit Retevis RB26 package from Amazon to use as an intercom system. They work great!  Three radios are in the bedrooms with other two in her kitchen and my office.  I used Chirp to program the key lock function on the PF1 key.  It came programmed for monitoring.  My kids would sometimes hit the PF1 or 2 keys instead of the PTT key and change the channel.  The only bad thing is it will return to unlocked if powered off, but I just have to press the PF1 for a couple of seconds to lock the keys again.
