[R-390] R-1051

[Bob Camp]

Hi

This is from about ten years later but I suspect it is also relevant to 
the comparison.

The first R-390A I ever played with I picked up with at Fair Radio in 
about 1972. It was a Saturday morning and business was slow in Lima. We 
went back to an warehouse that was full of an enormous pile of 
R-390A's. I picked one out and we carted it back to the main office to 
run it through a basic check before I drove it back to Rochester.

Along the way we passed a stack of these odd radios with a bunch of 
knobs on them. At the time I had no idea what they could be, but I have 
sense figured out they were R-1051's. The stack was pretty good sized, 
but no where near as big as the R-390 stack. I asked about them and the 
comment that came back was "FMS (Foreign Military Sales)  nobody seems 
to want them in this country".

The 1051 has been suffering by comparison with the R-390 for a long 
time ....

	Enjoy!
