[Premium-Rx] Microdyne information

[Glenn Little WB4UIV]

This may not be a premium receiver, but, this appears to be the best 
place to ask about it.

I have a MR1400 telemetry receiver that I just got.
It has a 1420-I series IF Filter with a 100 KHz bandwidth installed.
This filter is a 20 MHz IF crystal filter with 100 KHz bandwidth.
I also bought a 1420-I Series IF Filter with installed bandwidths of 
2.40, 4.00, 6.00 and 10.0 MHz.
These filters are LC filters.
I bought this filter in hopes that I could convert the bandwidths to 
something more useable for communications.

Does anyone know where I can find information on this filter module?

I can reverse engineer the filter, but, it will take a little time.

Any help greatly appreciated.
