Hi, I've noticed that I get a significantly lower power output when transmitting in THOR22 with the integrated modem than in do with PSKxR. It seems to be about 6dB down. I get roughly the same power output in THOR22 and PSK500R from fldigi. There may well be good reasons for this that I haven't though of. If so, I'd be curious as to what they are. MSK16 seems to be similarly affected. Cheers, Darren, G0HWW
