I am trying to program a new Retevis RA87. I have tried to use both the Retevis software and CHIRP. I am having trouble with both, so I have two different questions. First, using the Reetvis software, How do you program in non GMRS frequencies for monitoring only ? Second, using CHIRP, I am getting an error when I try to download from the radio. I get the error "Radio Identification Failed" I am using the cable that came with the radio, I have the correct COM port set, I have the correct Vender & Model set. ??
