[R-390] R-390/R-389 CG ship installation

[Don Reaves]

Stan, I'm not sure what those Teletype machines are.  They look similiar to
ASR-33s.  Perhaps someone will recognize the exact model.

Tom - that's interesting that the LF/MF 389s were replaced with HF 651S-1
units.  I've had both and the R-389 outperforms the 651S-1 handily below
500KC.   I note there was an option to the 651S-1 that extended coverage
down to 15KC but my specimen didn't have that.
