I'll submit that the KAT500 was designed long before 630 meters was
generally open and the values needed to present a low SWR are far larger
than needed elsewhere. Anything below 160M is a 'specialty' band that
far fewer will attempt. However you COULD go through the values that
the KAT500 offers manually and see if something could work.
You could use an antenna analyzer in SWR mode (fixed freq not sweep) to
tune the antenna at almost any frequency (at flea power, all legally).

Andy -
You bring up some good points, and I will be watching for the input from the
assembled brain trust.
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
630 meters. No such luck with the KAT500. If there is a workaround, I'd
like to hear what it is.
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.

Subject: [Elecraft] KAT500 antenna selection
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 closest to the out of band operating frequency?
