630m is a 7-KHz wide band. Probably not requiring an auto-tuner.
Most on 630m will be running a very short antenna in terms of
wavelength which usually incorporates a large loading coil in series.
My 630m antenna is an Inverted-L 43 by 122 feet and I have a base
coil to ground which tunes

Have you tried it on CW? Before resorting to shipping it back to the
factory, it would seem this is a simple way to determine if it’s an RF or
an audio problem

For gosh sake, there are published specifications for the KAT500. Page
2 of the manual. If you are trying to use it outside of the published
specification then you are accepting the role of a very under paid
design engineer. Talk to your boss about a pay raise but don't blame
it on
"Also keep in mind that tuning it on "off band" frequencies requires that you
transmit a signal of at least a minimal value ... which is technically not
legal."
No that's not true. The KAT500 can be set to any frequency within its
operating range by sending it the frequency on the serial bus

One issue I have with the KAT500 is that it only goes down to 160 meters.
My previous tuner would handle much lower frequencies, allowing me to work

The KAT500 has continuous frequency coverage for saving and selecting tuning
solutions and is not constrained to amateur band limits. However, the antenna
selection can only be defined for the amateur bands.
Does the KAT500 simply use the antenna selection defined for the amateur band
