So, these GE Orion/ MAcom/ Harris radios seem to have been produced over a wide range of time with many different models that look similar. I'm brand new to them and so I don't know exactly which ones to look for for ham use. I know there is a 110w VHF model that can be modified to be used from 144Mhz and up. I know there is a few UHF models, can either one be modified to cover the entire ham 70cm band? (420-450Mhz). What models should I look for? It seems the MAcom branded models with blue strip may have less p25 capabilities or something. Does anybody know the time frame, or is there a time chart that explains what year the different models were released and by what name, as well as differences in capability if any? I don't even know the naming conventions, was the radio the "ericsson" under GE, the Orion under MAcom, and the XG100 under Harris? I know nothing... I will continue to do research, but the goal is cheap durable mobile radios for ham use. I understand there is a learning curve, and I will need to obtain the ProGrammer software or EDACS, and will then need to learn how all that works, so any advice here on what to look for and what to stay away from would be helpful. I haven't made any purchases yet. I think ideally I would have the 110w VHF and 50w UHF rigs connected together (however that is done) and then use that hand mic that can be used as the control head.
