[Boatanchors] Oddball 50 Kcs Homebrew Receiver

[Whitebear1122]

> I’m trying to ID a very interesting and very strange home-brew receiver..  At first I thought it was a DCS500 because of the 50 Kcs IF  but I don’t think so now.  This item is built in a 19” rack panel/chassis, National dial on the front, handful of controls.  It has 12 Miller 1884 50 Kc IF transformers on a raised chassis on top of the main chassis.  It also has two Miller 912-W2 oscillator coils for 1400-1600 KC on an elevated chassis connected to the front panel dial so obviously the oscillator.

> It looks like some huge 50 Kc IF filter at a minimum.  It appears to be bandswitched though, not using plug in coils, but bandswitched miniature coils.
> 
> I found a data sheet from JW Miller for a “High Q 50 KC stagger tuned band pass coils.  It shows a schematic of a big band pass amplifier.  I’m wondering if the OT made a receiver out of it with an RF front end and mixer.
