[Milsurplus] Unknown "DF" Mechanical Filter

[Al Klase]

Hue,

The Wikipedia article on R-390A has a list of manufacturers of that 
radio that includes:
"Electronic Assistance Corp 15,338 (includes Dittmore Freimuth marked 
radios)"
I didn't know about that, but I think it's your answer.

On another note.  A long time ago, you suggested that if there wasn't a 
hamfest, you could root through your own stuff, and find something 
unexpected.  I feel a lot of us have passed beyond the Miller Threshold, 
and can do the same. ;-)

Best regards,
Al
