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...

Drake already did that. They took a TR-4CW, converted it to all solid
state and repalced the PTO with a synthesizer. Called it the TR-5.

Nice rig, but they only sold around 1500 of them.
