Dan -
No real difference between the '3 and '4. The only practical place to pick off the frequency is at
the output of V3a. Obviously this requires a counter that is 'offsettable' by the 9 MHz Carrier
oscillator. A second offset would be required for CW readout.
On the other hand, do you _really_ need to know your frequency to better than
a half kHz???

I have a Palomar PD-700 digital readout that I believe should work with the TR-3 or TR-4. Of
course there are no schematics or manuals available for this unit anymore. I can get the unit to
readout and track the 5mhz vfo but cannot figure out where to connect the oscillator to give
actual frequency readout. Anyone have experience in connecting a digital readout to either the
TR-3 or the TR-4? I have both and would settle for being able to get it to work with either one.
Thanks; Dan
