I am a ham radio operator, and I like the idea of restoring a military vehicle with the proper radios in it, but trust me, when I build my CUCV it will have a non-functional RT-524 radio in it for display, and for comms I will install a mobile 2-meter transceiver from a commercial manufacturer. Just ease of operation, power requirements, ability to be heard without a sideband conversion, etc. Lots of reasons why commercial is better.
And if you don't have a ham radio license and try to broadcast on those freqs, FCC will gladly triangulate your position from your own transmissions, take your equipment, and fine you $10K. It happens sometimes, so don't think you're clever and try to get away with it. Plus, there are kids under 10 years old who have a technician class license. The test is easy to study for (at
www.qrz.com) and the tests are given all across the country, so it's not like getting one is rocket science to get on the air. Why not just take the test, know where you're supposed to operate in the band plan, and be 100% legal?
