Baofeng UV-5RM

[Randy222]

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

Hi.
Have tested what was the tx freq low/up limits?.

Hi.
Have tested what was the tx freq low/up limits?.

Out of the box, just the lowest and highest frequency that I can key up?
These are just two points, other bands have restrictions on them (out of the box)

Lowest is 136.00000MHz
Highest is 519.99875MHz

I have seen a few Baofeng radios on spectrum analyzers.   They all had terrible harmonics on 2 meter band.  Do not recall if I have seen other bands analyzed.

There's a few vids that show 2m harmonics, but not the other bands, but they then mention "works ok on the other bands". Not sure why they just wouldn't show the other bands on the test gear.
