New to ham so don't know much. Anyway I mounted a Yaesu FT-2500M in my Humvee. The SWR is around 2.0. My problem is that this radio has three output levels 5,25 and 50 watts. I installed a watt meter and it shows only about 2.5,10 and 20 watts. Sounds like Almost half the output. Any ideas as to the problem? Also can you point me to where I could send it for repair.

Thanks for the help.
