Description
I believe I have discovered an issue with programming Baofeng UV-6 handhelds. I have six UV-6 radios used with the Air Cadet organisation. Reprogramming them has shown the issue. I do not know what software or programming leads have been used with these radios before now.
I have used the latest Chirp download and consulted the documentation on the Chirp website but, can find no solution.
I have used 2 different USB programming leads, one with CH340 chip and the other with FTDI. The results are the same with both leads.
Using Chirp, I have read from a UV-6 that has not been reprogrammed and it does not show the symptoms. Programming another UV-6 with this image now makes the reprogrammed UV-6 show the symptoms.
Reprogramming causes these two symptoms:
1). When the radio is operated, both simplex and split frequency operation works as normal but when reprogramming with a transmission CTCSS tone (for repeater access), this results in the receiver audio being muted, but the green ‘signal received’ LED lights as normal. Pressing the MONI button during receive removes the mute and allows audio from the speaker.
2). The radio reports by spoken English the channel number. This is normally 1 to 128. After reprogramming, the lowest channel number is now zero. There is no channel zero on the Chirp screen.
