Or, for that matter, try it into a dummy load, so that you can verify
the performance of the KPA-1500's tuner on 160.

Do you have actual antenna measurements with an analyzer? It would be
helpful to know what the KTA500 is seeing.

Be sure the K3 tuner is off when using the KPA1500’s tuner.

This morning I put up a W7FG true ladder line 160M doublet. Upon testing,
the K3 internal atu does great, matches at 1.3:1. But when I throw the
KAP1500 in line, it gets all pissed off, throws up and faults out. Says
SWR
is 99:1 !!!
The Antenna: The Apex is at 50'. It is in a inverted Vee config, with
both
ends approx 20' off the ground. I'm using 59' of the 600 ohm true ladder
line to a Balun Designs 5KW 4:1 Balun. This is fed with 22' of Wilson
LMR400
Both the K3 internal atu, AND the KPA1500 internal atu get a great match
on
80M, 1.2:1 with no issues.
Honestly, most of the work on 160M is FT8 running 20 watts or less, so
just
using the K3 to get a successful match on 160M is fine
I just wonder why the KAP1500 doesn't like the same antenna the K3 likes.
Any ideas here fellers?
thanks and 73
