Many thanks Ron and Gary,
I will read that QST Mod too. I have the schematic for the TR-4Cw/RIT too
(plus I have one of those so I can actually look into it phyiscially) and
its simplicity got me going. But, as Gary pointed out, there seems to be
some delicate work in the PTO that will need attention.
This is the kind of activity I should be doing in the Winter. Too many
weeds to pull outside :>)

Kris,
Not sure how well this fit up, but there was an article in QST for adding
RIT to the TR3. I had it on my TR3, but backed it out before I sold it.
Jun 1966 - QST (Pg. 20)
Offset Tuning and F.S.K. for the Drake TR-3
Author: Swanson, Elston H., W2PEE
Although I can not speak for how to do this in a TR4cw, the concept is good.
You might look at a schematic of the TR4CW/RIT and see how Drake did that.
Might work for you better than the article on the TR3.
Let the group now how it goes.

Day dreaming again! I am
working on the restoration of a nice TR-4C. One of the
great improvements on the TR-4CW was to offer the RIT.
Looking at the RIT board in the manuls makes it look like a
snap to make one and add it to the TR-4C and replace the NB
off/on swicth with some sort of a 10 K pot that would have a
push off and off buiult into it.
Any suggestions?
