Cecil probably knows the answer.

Actually, I don't. My IC-706 certainly covers 60-66 MHz which
is channel 3 in College Station, TX. I jumped to the conclusion
that since I couldn't hear WFM audio anywhere on that band, that
the audio wasn't detectable until down-converted to the
intercarrier. It is possible that I hit some dead air time and
gave up too soon.

I just cracked open my TV reference book and it indicates there
are two ways to detect the sound, split IF reception and intercarrier
reception. What now seems most likely is that I didn't tune high
enough up to the 65.75 MHz sound carrier frequency or if I did
tune that high, I hit some dead air time with no modulation.

Next time I'm over there, I will try again.
