Actually, I have had success transmitting with the power adapter when the HT was on the lower power setting (med, I think).  Don't know about hum, however, but I was able to do APRS with it.  I also think it did work on high power when on a stiffer power supply (the shack's 13.8v system, via a cigarette plug).
