From a 1999 post, the scheme is apparently
signal frequency divided by 8 for transmit
and
signal frequency minus 10.7MHz divided by 9

The first puts the crystals in the 18MHz range, which sounds
right, but the receive puts them in the 14Mhz range which seems
a bit low.

But, some other posts show the same scheme, so it must be correct.
