I am using a K3 and KPA500 with the KAT500. I also have the KAT500
mode set to MAN. I thought that the firmware was supposed to switch
the tuner automatically when you switch bands? After I go to a new
band, I need to tap my key momentarily to get the tuner to tune to
the new frequency. Is this normal? Let me know as I thought the
tuner would remember the presets when QSY'ing to a new frequency?
Any help would be appreciated. Thanks.
Hmmm ... I have the control cables ... K3-->KAT500/KAT500-->KPA500,
I've trained my KAT500 for all 3 antennas on all the bands that each of
them work on, and I run the KAT500 in MAN. All indications are that the
KAT500 recalls the correct solution for the frequency when I QSY to a
new frequency or band.
I'm hardly an expert on the insides of Elecraft firmware, and I suppose
it could be recalling on very first sign of RF and doing so very quickly
so that I don't notice it, but I really don't think so.
I do notice when changing bands that the K3 power control sometimes
takes a dit or two to settle to the correct drive power ... often that
first dit will blink the 600 [occasionally 700] watt LED.
