Looking at a draft of the KPA1500 amplifier,
Dick,
I agree completely. Perhaps I was not clear. The P3 coupler normally goes -
not between the K3 and the KPA - but between the KPA and the tuner so that
It shows
the "adjusted" SWR as "seen" by the KPA.
The KPA1500 has a tuner built-into the same case.

I realize that, Bill but, Elecraft also makes a monitor accessory
for the P3. It should be useable with the KPA1500 but
appears not to be the case.

On the back of the amp there is a "TX SAMPLE" port to connect your P3.

Whether the TXMON add-on to the P3 "should be [useable] with the
KPA1500" is certainly an opinion you may choose to adopt.
Whether Elecraft wants to implement your desire for lifetime forward

Well there ya go!
Thank you Elecraft! Thank you Mr. Rhodes!
