Hello colleagues, I have been trying to program Vertex-Yaesu VX-2200 mobile radios and I either get a OPEN COM ERROR or COMMUNICATION ERROR. When uploading radio information or downloading, the radio display goes from SELFTEST to PCPROG to SELFTEST. The software is CE82 for Windows and the cables are what was recommended in the owners manual. These radios I purchased on E-Bay. Any suggestions? Thanks!
