Sounds like the PTO dial has been slipped 100 kHz. If you use XMTR
control TRANSCEIVE and then tune to 7240, do you HEAR 7240? Stated
another way, if you tune the receiver PTO to 7240, the transmitter PTO
to 7340, and switch between SEPARATE, XMTR and RCVR, do you hear the
same signal in all three positions?
If you do, the transmitter PTO dial will have to be reset. There are
one or two spring loaded levers, depending upon the age, that extend
over the top of the "gearbox" of the PTO, just behind the dial. If you
push either lever towards the centerline of the PTO, it will disengage
the gear drive for one or the other dials, allowing it to rotate
freely. So... With the transmitter PTO set to 7240, press the
appropriate lever and rotate the 100 kHz dial to read 0.240 and release
the lever. It may take a few tries to hit the exact gear tooth to make
it line up exactly under the line, but ... One caveat, when you press
the lever(s) the dials spin FREELY, and you can lose your place entirely!

Part 5 shows these levers and explains the procedure.

I have a question in regards to the alignment. I have a R4C and a
T4XC. When I go to the spot mode for putting the xmitter on the same
freq. as the receiver, it is 100 kc off. Example. I have the receiver
on 7240---- 40 meters and put the xmitter on 7240 no birdie sound. If
I put the xmitter on 7340 I get the birdie sound. This happens on
every band. Trying to trouble shoot the problem where to I start. I
am new at working on this equipment so really don't want to mess up or
ruin a good piece of equipment.
Any help would be appreciated on this matter. 73's Dave WB6BIL
