Hi,
I am glad to inform you that I have updated my 'xtalfind' program to
include tests for software defined DC receivers and DRM converters.

xtalfind is a Perl script that, given a (list of) XTAL frequency,
returns all its possible uses for HAM applications, (sub)harmonics
included. Currently xtalfind checks for the following matches:

* DC RX or TX (HAM bands)
* RX with 455kHz IF (HAM bands)
* RX with 10MHz IF (HAM bands)
* RX with 12kHz IF (HAM bands)
* RX with custom IF (HAM bands)
* SDR LO=4*F (HAM bands)
* DRM converter 455-12kHz
* DRM converter 9011-12kHz (ICOMs)
* DRM DC RX for known DRM broadcasts

You can see a sample output from a previous release at
http://spazioinwind.libero.it/ik1zyw/hardware/myxtals

You can download the software from
http://spazioinwind.libero.it/ik1zyw...ind-2.0.tar.gz

The Perl interpreter is available for most operating systems, so
xtalfind should run almost anywhere.

Don't throw a XTAL before asking xtalfind! :-)
Never underestimate the power of weird frequency XTALs! ;-)
