The presented lowcost standart crystal frequencies are selected for
the usage in superheterodyne sideband transceivers (receivers). For
extension
to this list, look at 7N3WVM's
homepage.
Makoto,
in
addition
to
his
list, shows a block diagram for superhets,
and provides excellent information about VXOs. The frequencies in this
list need in some cases multiplification with a given factor M. The
intermediate
frequency if is shown for superhet designs. Crystals for the
intermediate
frequency have to be fundametals for easy to build SSB/CW ladder
filters.
Where the frequency multiplication factor equals 1 you might swap VXO
and
filter frequencies, depending on your junk-box/requirements.

(*) not for IARU region 1
(**) CB-crystal 27.015 MHz
(+) here is a mixer xtal available at 4.194812 MHz
(++) combination found by Juanjo - EC5ACA
(+++) combination found by Klaas - PE1MJZ
(?) questionable, intermediate frequency rather high
This list cannot be complete, and it is not claimed to be complete. If you feel the wish to respond, add new xtal-pairs, or send donations ... please do not hesitate to do so. But, remember that those crystals should be really inexpensive.
