Hi Jim, My Pixel loop is about 15 feet away from my BigIR vertical. I run 1500 watts QSK and have not had any problem at all. In fact since the recent improvements to the K3 QSK it's become a pretty pleasant way of operating. As Vic stated, there is a mechanical relay in the Pixel power box that resides inside the shack which could be distracting. However, the clicking from my amp's relay is much louder. So headphones are pretty much mandatory at my QTH. I should note that this amp is new and I've only been running QSK for about 5 months.
If you are noise sensitive and if you are running a silent amp like the KPA500 you'll probably be dissapointed in the sudden appearance of noise from the Pixel power box. I don't know how the Wellbrook does its switching. Perhaps the bigger question is how many cycles does this little relay go through in a typical weekend DX contest and how long will it last. Is it 10,000 cycles? Is it a million cycles? I always switch the Pixel off on the higher frequency bands for the sole purpose of extending the life of the relay. 73, Mike K2MK James Bennett wrote > Hi all, > > Have a K3/P3/KPA500/KAT500 and have been working 160 meters more the past > year or so than in the previous 49 years.
