I've had one of these for a long time. I asked about support and was told they needed a Radio to test it. I offered my radio but no taker. 

I don't know it its been tested but I'll give a shot  

I installed the  new Chirp and looked for my cable. Took a while,  but I found it..    

Guess what  IT Works Thanks Gang I really like it......   John KE4EGC !!!!
