KAT Problems

Paul Ecker
Bob- followed your suggestion and edited the KAT configuration Antenna tab
to: Bands – ALL ; Enable - now have 1 2 and 3 checked and for Preferred –
Last  Used. Then saved the configuration. It had no effect on the problem

-       I still can not select ant 3 for 160. In fact even after making
your suggestion changes to the KAT config, can only select ant 1 for 160,
80 and 40 meters.

-       Cannot do the Train the Tuner on either 40 or 160 meters

-       Additionally have noticed that my KPA500 is not sensing and
changing bands on 40 or 160m. On all other bands the KPA does shift bands.
In the KPA500 Utility _ Operate TAB neither 40 or 160 show up when Tx’ing

-       The radio tunes and transmits fine with the KAT and KPA500 in Bypass

73 & tnx

Re: KAT Problems

Paul;
When you transmit on either band, does the KPA500 display an asterisk on the left side of the display? This would indicate that the KPA is being PTT.
If so, Place a wattmeter in the RF path between the transceiver and the KPA500. That should give a good indication as to the power getting to the amplifier (and thus KAT500).

I suspect there is no RF getting to the amplifier on the bands you are having problems with. Either that or no PTT signal on those bands. If this is configurable in the radio, then find the selection and set i two its proper value. Otherwise try to figure out why no rf is going out on those bands.

73!

Re: KAT Problems

Paul Ecker
Jack & all others that have helped on this question, I posted. Problem
solved. Turns out the issue was a bad connector on a coax jumper running
from my 160M antenna  disconnect switch  to the KAT 500 and  having wrong
antenna selected in radio. Bottom line: KAT500 and KPA500 both working
great now. So thanks again to all for helping. Lessons learned have been
entered in station log.
