I'm looking for xtals on the 72 MHz RC band. They seem expensive from
the hobby sites. Does anybody know of a better source? In particular,
I'm looking for a few on channel 24, which is 72.27 MHz.

Thanks

The FCc stole much of the band for some other service.  Used to be RC
xmtrs didn't need xtals.  http://www.lagmonster.org/docs/allochrt.pdf
and click on 30-300MHz and scroll over a bit.  (.PDF)



rc channels 11-60 are area are 20kHz apart, starting at 72.01 MHz.

AFIK, all RC transmitters and receivers use crystals. The FCC probably doesn't want RC transmitters broadcasting random PCM into TV channel 4, interrupting those soap operas.
