The KX3 isn't perfect. During SOTA activations, Gary W5ODS and I each use a
KX3, with the roofing filter option. He with an end-fed wire, and me
usually with an AlexLoop. I can often hear his code (a pink noise sound)
even when he is in a band higher in frequency, as well as when I am in a
higher band and he the lower. Sometimes turning on RX SHIFT 8kHz knocks it
out, sometimes it doesn't. Turning on the attenuator or lowering RF gain
doesn't seem to knock it out either.
Is that phase noise or another phenom?
Don't get me wrong, I do love the KX3.
