In the latest AW&ST it mentions the F-22's radar as having a range of
"over 100 miles" and implies that it's greater than the F-15's. I
recall reading MANY times in the 80's of the Eagle's radar being more
like 150 miles and the Tomcat's nearly 200.

Depends on your target. If you're looking for a Bear at 40,000 feet then
you'll get ranges limited by the max scale on the scope That number
makes for a good advertising brochure, and isn't even unfair since the
Tomcat (and the F-15 if doing 'home defence') was worried about Big
******* Bombers back then.

I've also read that the
ASG-18 in the YF-12 (which was the one the AWG-9 was based on) was
good for over 300. So what gives? Are they purposly underselling
the APG-77? Is the "over 100 miles" figure against fighter-sized
targets while the high figures of the other radars were against
bomber-sized targets?

I'd guess exactly that - started to write the above and then realised
you'd hit the same point yourself. If you're defending against Bears,
Badgers and Backfires then radar ranges against large bombers/airliners
are fair comparison: these days I'd guess the figures are for more
fighter-size targets.
