Many of videos on YT says "it is the first 40W output handheld" on the market or even worse I heard about 80W etc. Marketing guys are always ready to lie in order to raising up their selling numbers... So let&go to measure it using professional test and fully calibrated equipment in order to check what is the real power on the 70cm band. Combined uncertainty is not calculated but if you want it then I can make some video how to calculate it for this measurement. Also be noted that additional insertion losses represented by adapters and jumpers are not calculated and are not included in the measurement.
