When you are ready to upgrade your radios, give Brian at Action Communications a call 800-214-6011. They helped our club transition from cheaper Motorola radios and also provided us with compatible excellent replacement ICOM radios as we could afford them. We just changed the cables out on the headsets as we upgraded.
If you ever do start to upgrade your radios, check out the ICOM IC-F4011, Action sells them for around $160 shipped and they are bullet-proof and have LiON batteries. We’ve been running on ours now for over 3 years with no radio or battery failures, and they get absolutely pounded by our volunteers..
