I think you mean Moore's law. Regardless, lately I find that I buy stuff
that I already have several of, HI. 73 - Mike

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

Anyone here know about a mechanical filter, blue color finish, 2 screw
mounting with 3 pins at each end, similar size to small Collins, 

with "DF" logo in circle, and this number on it:  No internet info found !

 

TYPE D.F-455-U-2.3-H      ( may be DF or D.F. )

P/N  7232-528-3

 

After today's hamfest, I decided I should hamfest at my storage, and I found
this and 2 new boxed Collins 455 2.1 filters. Hmmm...

I had no idea I owned these! 

thanks-
