If you go into the "Xcvr Sel" menu and select the last item on the list,
"0 Hz" then the display will indicate the correct RF frequency at the IF
input connector. You can tune around by pressing the CENTER key. (Do
this with the K3 not connected to the P3 RS-232 port.)
As Eric mentioned, the P3's IF input has no over-voltage protection,
which is not a problem when it is connected to the K3 IF OUT, but if you
plan to connect an antenna directly to the P3 you need to protect it
from static discharge. A pair of back-to-back switching diodes in
parallel with the IF IN connector works fine.

Jim,
The P3 does only receive 200 kHz around the selected IF frequency.
The P3 is not dedicated to the K3, so it can cover a wide range of IF
frequencies. That means it is "tunable" (via the menu) from 455 kHz to
21.7 MHz. One way to do it is set the XCVR SEL menu to "User" and then
set the frequency of interest using the XCVR DEF menu. If you only need
to cover a portion of the spectrum that is the IF programmed for one of
the transceivers listed in XCVR SEL, you do not have to mess with the
XCVR DEF menu.

I think I missed something. I thought the P3 is IF only How does it
receive more than 200Khz around it's passband?
