I have some question about the operate tab in the kat500 utility.
In the "others" what should be checked off?
"caps on the Ant side"
"amp key interrupt"
"attenuator"
Not sure what these things do.
I had been using my kat500 for years and all of a sudden low SWR matches

If you don't have a specific reason for changing these values you should regard
these as sta
Let's start with the basic facts.
Rig --> amp --> KAT500 --> antenna/s (with the tuner blocking the amp
key in while tuning).
1) The KAT500 was working successfully 'for years' without issue.
2) There was a sudden change in operation.
This doesn't necessarily mean it was the tuner; it more
Hi
Well I checked the antenna and it is just as before the problem.
Is the capacitor setting normally checked by default?
This setting was not chosen automatically.
After I enabled the capacitor setting the tuner tuned immediately to a
low SWR on the low end of the band.
I noticed that n
" Is the capacitor setting normally checked by default? This setting was

Cap Side is set to SIDET (transceiver side) when the KAT500 is in Bypass mode.
At any other time is is set to the value corresponding to the current tuning
solution. That tuning solution ma
"Take a look at this reference - https://leleivre.com/rf_lcmatch.html if you
can't visualize what Cap Side is doing."
I should have added that the upper two topologies are the only ones that can be
set in the KAT500. The inductors are always in series and the capacitors are
always in parallel
Hi
I believe for some intermittent time the tuner did not move the caps to
the antenna side. It is working now though.
All these boxes we have are computer controlled. I
Thanks all
