Default COMMON IF FREQUENCIES FOR LMR & HAM GEAR

I am trying to compile a spreadsheet of common IF frequencies used by
VHF, UHF and 800 MHz land mobile and amateur gear. Apart from the
standard 10.7 and 21.4 MHz first IF and 455 KHz second IF frequencies,
there are a number of "odd" IF freqiuencies in use.

This information will be used to make a database for determining local
possible oscillator frequencies leaking/emanating from radios.

For example a Standard C508A radio receiving on 442.575 MHz will emanate
an LO leakage on 442.575 - 23.05 MHz (First IF) = 419.525 MHz.

I would appreciate response (to this thread not my "bogus" e-mail
address) from anyone who has knowledge of odd IF freqs:

Please respond as follows:

Manufacturer: Standard, Model C508A, First IF: 23.05 MHz, second IF 450 KHz.

Thanks for help with this project.
