[Milsurplus] AN/ARC-9?

[David Olean]

Hello Jack,

I have had a Bendix fetish for many years. Reason is that as a young ham 
of 16, with no money, an RA-10 was all I could afford for a receiver. 
Fair Radio had them for $32.95, but for $22.95 you could get the limited 
coverage FD version that eliminated the BC band. That is what I got, and 
used it for a few years as a tunable IF for my 144 MHz converter.  I 
always loved the cool look of the tunable control box.   It took me many 
years to find another one. Along the way, I got an MN-26C and a RA1B as 
well.  Mine are all restored and working FB.  I use the MN-26C to pipe 
music into my workshop. I found a local radio station with no ads that 
plays 40's and 50's music all day. I guess I still have a Bendix fetish, 
but am being realistic about it.  I am at a point in my life when I 
should be off loading stuff!!
