I don't have any way to measure power here at all, I have a fairly junky SWR meter but wouldn't be useful for this at all. I've eyeballed a few SWR/Power/Frequency counter doodads from places and all of them say no DMR.VK3KYY wrote: ↑Fri May 15, 2020 1:24 amDid you calibrate the power output on both radios.. Otherwise they won't be producing the same power.
Even if you have calibrated the power on both radios, the 50mW power setting varies a lot between each radio, because the Voltage vs Power output response on the PA FET in each radio won't be the same, as the calibration points are only at 1W and 5W
If you calibrate both radios for 1W and 5W and run both radios on 1W they are likely to have the same range in both directions, but even then, they may not be both equally well calibrated for their 4FSK deviation, and you need specialized test equipment if you want to calibrate that as well.
I actually only have one GD77, although I'm seriously considering getting a second one because this works so well. My mmdvm works fine, but it feels like the GD77 works better, less distortion. Around the house, RF performance is all the same.
