I just repaired my TR-3, and put it on the air. I'd forgotten what a
nice rig it is. Now, I've started to think about how much better it
could be. What if one was to rip out the entire frequency control
section (VFO, xtal osc, mixer, etc) and replace it with a DDS
synthesizer. It turns out that the display would fit in the opening of
the tuning dial. There would be excellent frequency stability, no
backwards tuning on 20M, 2-3 less tubes to save heat and power. It just
wouldn't be a Drake anymore...

And don't get me started on a lightweight switching supply to replace
the AC-3. I might do that anyway, since I wouldn't be destroying any
hardware.


ARC-5 Command Set receiver modification instructions for conversion to a
single band SSB transceiver.

Step 1. Remove all components except the variable capacitor...


Been there, done that. Well, not SSB, but my first rig (1969) was an
ARC-5 conversion. I actually got to keep quite a bit of the guts and
still make a few QSOs. It was paired with a Hammarlund HQ-120X...
