Got a new set of low cost radios to play with. Watched many online vid reviews and their testing. Most of those vids were from early days of the 5RM release. Not sure if anything has changed but here are my test results.
Test gear is tinySA Ultra v1.4-177 , and MFJ-842 power-swr needle meter
UV-5RM firmware v0.14 hardware v01
out-of-the-box testing, no chirp tweaks
