On another note, did you ever read that QST article the modification of the
Drake TR7?

OK Ace, ya got me. what about the article on moding the

TR7?

Apparently there is an article in a recent QST that describes adding DSP to the TR7.
I was interested if anything in the article might also pertain to the R7.

i have been wanting an R7, but the prices are out

of reason. i do have an MSR-2. i believe that passes

as the marine version of the R7.

No, the MSR-2 is I think a totally different animal (because of the switch selection
of the readout). What was once proposed was the MR-3, which is a repackaged R7:

It never went into production. This from elsewhere on the site:

Interview of Ray Midkiff, Father of the DSR and MSR Main Marine receivers

Just rcvd. your e-mail on Drake products. The RR1, RR2, and RR3 rcvrs were modified
versions of the SPR4 Rcvrs. designed to meet the Marine Reserve standards. They were
designed by Bill Robertson (no longer with Drake) and Steve Koogler (presently at
Drake).

I designed the DSR-1 and DSR-2 receives intended as a commercial or laboratory
synthesized all band unit and also the MSR-2 unit that was designed to meet the
standards for a Marine Mains Rcvr.

The MR-3 (repackaged R7) would not have met the Mains spec.
