I just tried it at speeds from about 24 to 35 wpm. As you say, not much difference in what you hear and a big reduction in relay operations. 0.005 extends the useful speed range downward without changing what you hear much. I'll try it in the next pileup and see if I think it matters. I have t

Is there a significant benefit to running full QSK at speeds >= 30 WPM as opposed to just running break-in w/ a delay of 0.04? I use the Pixel loop here on 40 and 30 meters w/ my K3, and doing the latter saves a lot of relay operations. Although you won't hear the band between keying elements, you

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 r

The Pixel can be connected to your amp key circuit. It turns off the power and grounds the antenna on transmit. It works fine with the K3 QSK at 30 wpm (haven't really tried it faster). The relay is a little noisy, but I wear phones and it doesn't bother me. I am using it about 6m from my verti

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. Only need three more states for WAS. Got a lot of noise here at this QTH, and have limited antenna space. Using an Inverted L up about 40 feet with a K2AV FCP under it. I
