Hi Gary,
?
Yes I have one Piezo Technology original first IF roofing filter on the shelf.
?
I also have a parts R-4C that has been cannibalized, but has the power transformer and a PTO.??
?
Another more complete R-4C S/N 16354 that is modified for a lot of AM filters.? Otherwise appears complete if someone wanted to part it out.
Filters:? 6000 Hz, 4000 Hz, 3000 Hz AM, and a 1.5 kHz SSB/CW/RTTY filter.
Stock 8 kHz filter.
4 DPDT TO5 Teledyne relays
PTO
XFMR
100 kHz calibrator
?
Both R-4Cs have a reasonably good case with some scratches.

My wife says downsize old stuff.? Hi Hi? Please contact me direct at?Rob@...?if these could be of use.

Misc. parts still in inventory at?.? However no upgrade kits now that I have retired.
If anyone needs a few items to complete an R-4C project I have a few left.
Plug-in filter brackets
AUX crystal covers
Some shortwave general coverage HC-6/U band crystals.

Hello, I'm new to groups so if I mess up something, I apologize in advance.
I'm looking for an IRAD guf-1 for the 1st IF
Preferably the 2612.1 (8kHZ) although I would consider the 2611.1

Thanks,
Steve?
