xtalfind checks whether any XTAL is suitable for a HAM radio circuit (TX, RX). Given a base XTAL frequency, it shows you all possible uses within HAM bands. It features CW TX and direct conversion RX. It supports 455kHz, 10.7MHz, and custom IF value receivers, DRM, and SDRadio applications.

Release Notes: This release adds support for www.idt.com ICS512 and ICS672 clock multiplier chips, support for an MCW optical TX system, and Italian 4m sub-bands (temporary allocation 2007 and 2008). It adds a single-test switch to reduce output verbosity.
Release Notes: xtalfind was rewritten in Perl. Checks were added for Software Defined Radio (zero-IF IQ receivers), 12kHz IF, DRM-like converter 455-12 kHz, and 9010-12 kHz (most ICOM receivers have a 9Meg 2nd IF). A check for DC DRM RX according to a frequency list of broadcasters was added.
Release Notes: It is now possible to check XTALs for possible use with a custom IF value. The IF value is no longer restricted to 455 kHz or 10.7 MHz
Release Notes: The ability to mix XTAL base frequency (and harmonics) with a fixed frequency has been added.
