Measurements Are Only As Good As Your Tools

Today I got a mic connected to the uBitx and a key and was able to test that its making RF and doing its thing. My home antenna is resonant on 40m, so i do not need to check the swr or anything, but i thought i would use the power meter in the swr meter to check what the power output of the uBitx is. Trouble was, it was making about 5w cw and 3w ssb.

So i got to scratching my head and wondering about the radio itself. I was about to put it in the cannot be bothered for today pile when i grabbed down the scope probe, put it across the antenna port and keyed up cw, 22v rms or 10 watts out, so i grabbed the mic and spoke in my normal voice, 21v rms or about 10w out.

Obviously the power side of this swr meter is kind of crap and not giving an accurate measure of power out. Anyway, i know the uBitx is working now and making enough power to be useful, now all i gotta do is get out portable and use it.
