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 vertical transmitting antenna with up to 1200 watts, so it is a good
idea to use this feature.

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'm looking at perhaps getting a magnetic loop receiving antenna, and
have looked at the Wellbrook ALA 1530 and the Pixel RF Pro 1B.
But my question is on the T/R switching of the K3. As I operate 99%
CW, I depend on QSK operation. If I connect either of those receive
only antenna to the RX Ant, does the K3 switch between Ant1 and the
RX Ant fast enough to protect the K3?
Thanks, Jim
