Alignment...

As I mentioned in my last post, my FRG is in need of alignment - tuning at the bottom of each band is cramped and non-linear, it falls about 50kHz short at the top end of each band (when it should go about 50kHz past the end), and the whole thing feels a bit insensitive (which may just be psychological on my part).

That's not unusual; as far as I know, the set has never been aligned since it left the factory 30-odd years ago, and being kept for a few years in a hot shed won't have done it any favours.  At least it hasn't been "adjusted" by someone who's skills would be more in demand in the meat production industry than in an electronics workshop. Alignment isn't hard, and is quite well documented in both the instruction and service manuals, but it does require a few tools and a certain touch…

Straight after I finished building, testing, & installing the new PSU, I hooked the laptop up to the FRG-7700 and decoded the following images:
