[Elecraft] P3 - use as a transmit monitor

[Alan Bloom]

Cool Graham!

Actually there's an easier way to do it.  In the "Xcvr Sel" menu item, 
select the last item in the list "0 Hz."  The P3 frequency now reads the 
actual RF frequency and you can tune it by HOLDing the CENTER control on 
the front panel and then turning the knob.  (You may have to change the 
"Center En" menu entry to "ON.")

The tuning rate in CENTER mode is proportional to span.  Set the span to 
maximium to tune quickly and then narrow the span to zero in on the signal.

CAUTION:

Be careful when the P3 is connected to anything other than the K3 IF out 
because the P3 IF input is not protected against static discharge.  I 
would recommend putting a pair of back-to-back diodes in parallel across 
the input.  If you don't want to modify the P3 you can solder the diodes 
to a BNC male connector and connect it and the antenna to the P3 using a 
BNC "T" adapter.
