Jim,
That is correct - and you can confirm from the schematic if you like.
The receive antenna is connected on the same side of the T-R switch as
the PA transistor output. (the receive antenna is injected at the same
place the W1 jumper is placed in a K2 without the K160RX option.)
The receive antenna does not travel through the Low Pass Filter as the
normal antenna connection does, but then a low pass filter is not needed
on receive anyway, the bandpass filter provides all the per band
selectivity needed.
