I am using a KAT500 to control my station's antenna switching. Tonight when I
used a tube transceiver and amplifier, I would get a FAULT about every 5-10
minutes. Power was 650w. Here are the KAT500's parameters: f=7032, VSWR 1.13,
BYPASS VSWR 1.8, TUNE STATE 0 9 20 1.13, fm 1.67. Any idea
Eric,
What is the chance that the transceiver and amplifier are 'spiking' at
keydown time. That can cause a fault in the KAT500. Try turning the
power down and see if it continues.
Do you have the K3 and KPA500 as well? If so, does the KAT500 fault
when they are used?

The old tube rigs and their frame relay T/R are famous for glitching the
leading edge of the first dit or syllable. The problem with arcs is that
the arc is not just composed of the single frequency that is creating. The
broad signal resulting from the arc will be very highly invested with
