[Elecraft] KPA1500 with P3 Transmit Monitor

[Dick Dievendorff]

There is a coupler built into the amplifier.  It's necessary to implement
ATU tuning. 

The SWR the PA sees is displayed on SWR LEDs on the front panel, on a couple
of LCD "status" pages, and is available via the programming interface, where
it can be observed on the KPA1500 Utility's "operate" page.

Looking at a draft of the KPA1500 amplifier, it appears that the only place
to install  a TxMon or Wattmeter coupler is at the  -  output  -  of the
built-in tuner.

At that point, it will always show the SWR of the coax feedline, not the SWR
that the amplifier "sees" as adjusted by the built-in tuner.

Or, is there a coupler built-in inside the KPA1500 ?

What am I missing?
