I've passed this along on the forums before. But I'll say it again.
Assuming NO ONE has messed with the clarifier Fixed control under the rig behind the clarifier. LEAVE IT ALONE. Turn off the clarifier before you precede. Most of the time this control is fine, people just don't go in behind this control and turn this setting from my experience. It may have some white paint on it from the factory. Leave it alone.
Now hopefully you have access to a YC-601 or a frequency counter.
All we are trying to do here to get Tx and RX to coincide is to make sure there is NO Jump in VFO frequency when you go from RX to Tx.
Note: You do not have to have the heater on or the rig even tuned up to do this. All you are looking at is the VFO shift from Rx to tx.
IT'S SO SIMPLE. PLUG IN THE YC-601. Calibrate the receiver so it reads 7.000 or any frequency for that matter. I doesn't matter! it's not critical.
Just get it to read something easy on the eyes 7.100 / 14.300
3.900 what ever! Key the rig and see if the counter shits. If there is any shift, all you need to do is move the ZERO SET control on the regulator board to make it coincide with the receiver and you're done! it's a ONE MINUTE job assuming you have the counter.
I have been doing these rigs like this for years, you should be able to get the rig to settle in within a hundred Hertz accuracy which isn't bad for an old analog rig.

Now if you don't have the YC-601/B. You can take a standard frequency counter and connect it to the accessory plug on the FT-101. It's a green cable that comes from the VFO, the pin number escapes me right now.
Key the rig and make sure the VFO does not jump from Rx to Tx.
If it does, move the ZERO set control to the same VFO frequency as you have in Rx. Easy.

It's quick and dirty and works good.
