I used to own a HC-10 which was in a square, cubed actually cabinet, matching the HQ-180 knob layout. Maybe 10 x 10 x 10 inches per side. The HC-10 had a lot more knobs. It was actually the rear end of a HQ-180 complete with 60 kHz IF, and a 455 kHz input jack. The SPC-10 was the rack mount version of the HC-10 and had a similar looking S-meter, as well. This is not a SPC-10. It would fill a 19 inch rack slot without needing support plates. I still have manuals for both devices, which are possibly more collector's-item than the actual hardware... and the SPC-10 is a rare duck indeed. This device shown is not directly rack mountable, has way too few knobs to be either a HC-10 or a SPC-10, and the lower two knobs have round level marker plates, which I never saw on a Hammarlund product of that era (1962-ish), though the SP-600 had such. Maybe a "home" upgrade on those 2 lower knobs, for visual effect. My guess is that it IS a sideband adapter. If it had a nomenclature plate, I'd guess Technical Materiel Corp. though they DID have a tunable adapter for the GPR-90, I think it was the GSB-1 .... this is definitely NOT that. It could even be homebuilt- a one-off. That's my best guess. The panel work is definitely within the ability of a lot of "home" workshops. Truth be told, I don't know. The CEI is the rack mount device above the Collins, as stated. The four large knobs on the left edge of the photo look like part of a RCA broadcast transmitter, actually, but that does not make a lot of sense to have a RX next to an Xmtr like this. - Bob . _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
