A word of warning regarding the PA-II for those hams / amateur radio operators intending to install one:
The PA-II (or the included power supply, I didn't dig further into the issue) generates a huge amount of noise in the RF spectrum.
I operate it of the 230 VAC mains @ 50 Hz and the PA-II renders large portions of the HF radio spectrum useless. The PA-II isn't located anywhere near the antenna or transmission line systems.
Once outdoor temperatures get a bit more friendly I'll try replacing the power supply with another one to see if it helps.
