Interesting! I had not seen that one. Have you looked at it on a spectrum analyser? If you have only used a basic power meter then the power you measure could be higher on the harmonics and not much on the fundamental.I have the Radtel one and it is a Tri-band. Confirmed its outputting 3.5w on 220

If the radio does indeed output 3.5 watts on the fundamental, And you have your CTCSS/DCS tones correct, and an antenna that works on 1.25m, then I can't think of any reason why it shouldn't work for you.
