I had a chance to pick up a pair of these for $10, so I did. I have not been able to program them with Chirp - they refuse to go into programming mode.
VT-V68 did work… I found out you have to hold the flashlight button down when you download from the radio… but it’s missing some DCS tones, including the ones that I need.
So I tried the specific 888S program, and it seemed to be working, until I unplugged the radio and found out that, in spite of the program telling me otherwise, the data never filled to the radio. So, I’m still trying to get it sorted out.
