Does the Power Genius XL have full CW QSK capability?

    Resurrecting this thread as I am looking into the possibility of getting this amp. Not bothered about full QSK, provided that fast semi-break-in is OK (say 25ms or so) but slightly disappointed that changeover relays are used rather than pin diodes.

    How noisy are the c/o relays? Also, are the fans noisy in everyday (non contesting) use? I currently run the Expert 2K-FA and that is rather noisy in both respects!

    A while back I asked about the advantages of one of the other. I had several very smart rf engineers who convinced me that switching diodes can contribute to IMD and that reed relays are more RF-compliant.

    The flip-side seems to be MTBF - I've had to replace reed-relays around 30yrs of age. At low RF levels (TV modulators for Rogers, Shaw, Scientfic Atlanta) we found PIN diodes were an excellent answer with all IMD products down more than -65dBc. But I also believe that higher levels are a different story, as Mike says.
