I only have one RFI issue with my K3+KXPA100: running 80w on 50.125 SSB.

Seems my wife has her portable radio tuned to 100.1 MHz FM in the next 
room.  50.125 x2 = 100.25 "ouch"!

Antenna is 20-foot high on tower attached to end of the house.

Guess I need a "good" harmonic filter.

I had one on my Harris 1000w 6m amp (converted ch.2 TV amp), but it was 
sold with the amp.

When I get my MRF-1K50H LDMOS amp running 1200w on 160-6m will be 
interesting to see how well the LP filters do. <probably not QRV until 
spring, next year>
