Matching range of KPA1500 Built-in Tuner

[Phil Hystad-3]

I must have missed something to generate the exchanges on internal and external tuners and antennas with more than 3:1 SWR.

I am guessing that the matching range at 1500 watts for the KPA1500 tuner is limited?  Is it similar the KAT500 which is limited to 3:1 at 1000 watts?  Has the SWR matching range at various power levels of the KPA1500 been published somewhere?

 From the FAQ:

The amplifier’s rugged internal ATU can handle full power with load SWR up to
3:1, while a wider matching range is allowed at lower power levels, including up
to 10:1 in standby mode.

Sounds like it might be a re-packaged KAT500.
