[R-390] R-390 Frequency Label 4596.5

[James Young]

Hi everyone,

My recently acquired R-390 (1951 Motorola contract) came with a Dymo-type
label at the top center above the nomenclature tag that simply says "4596.5"
and it has me curious. Should I infer that my 390 spent countless hours
listening to this one frequency at some Cold War listening post? Or would
that be over-romanticizing the vague history of my receiver?

I will not pull the label off, nor would I paint over a blue stripe if I had
one. These and other artifacts are testaments to the serviceability of the
design and in the case of the blue paint, the indignities so many sustained.

If anyone has comments about the "4596.5" label I'd be interested to hear
them. Does it ring any bell or conjure up speculation about my 390's
previous life?

Thanks.
