[Premium-Rx] Collins Mechanical Filters

[Ray Robinson]

Hi Greg,

> There are three brand new Collins mechanical filters - military origin. 
> They are one of F500Z11LSB, and two of F500Z10USB. These are - I think - 
> 500kHz IF LSB & USB filters.
> Does anyone have a clue about the radio they would have been used in?

There is a web page with filter part numbers, filter characteristics,
Collins/Rockwell part numbers, and radios that use them at:
