I bought some Ebay Beofeng HTs before FCC screws with them. 5 and 8 watt , 2 and .7 meters bands with extra freq. beyond HAM.Only about 25 each. I always wanted a strong pair of walky talkys.I think there are easy to hack and use SDR tech
Check out RF circulators, used to stop back reflections.A 3 port device with a load on one port to arrest offending power.They are a trip to figure out but I think they could be usefull in our OU work.They use a 2 magnets with ferrite surrounding a triangle of copper with each point being one port.
