Here is the adjustment point:

Let the radio warm up for a few hours to get thermally stable, and
then flip upside down, remove the cover and make your adjustment. I
generally adjust for WWV at 10 MHz. You may need a small flashlight
to shine into the adjustment hole to make it easier.


A picture is worth many words. Thank you very much.


Yeah it's pretty easy to do and the trimpot is not that sensitive. The
Drake service manual recommends reading pin 1 of U35 and adjust until it
reads 35.00000 MHz +/- 10 Hz if the receiver has been warmed up for at least
2 hours -or set it to 35.00017 MHz +/- 10 Hz at room temp (if you don't
want to wait). Setting to WWV is, of course, just fine also.
