I was given (thanks, Tom - I think) an Intervox model 5DX radio-DF rcvr,
mfg by Radio Laboratories, Inc., of Seattle, Wash. And if this query is
not a total wash, anybody heerd of them?
The unit itself is cast aluminum, about an 8" cube, dark green wrinkle
finish, with a 9" round, screwed-together 'clam-shell' loop mounted on a
bearing on top, with aiming rods and a rotatable (tho stuck) compass rose
and pointers thereto underneath. The front has three controls: "L" (a
3-posn, multi-tap wafer sw), "P" (a pot with snap sw on the back), and
tuning (dual air-variable capacitor), from 275 thru 300 to 325 (I assume
kc).
It's battery-powered, with one 1.5v and a dual 45v - the 1LA6 loctal
converter uses 45v on the screen, while it and all five 1LN5 loctals have
90v plates. Judging from the tube numbers, the circuit is probably a
conventional superhet, but with headphone-level audio from a 1LN5 into a
pair of pin jacks on the front.
It looks pretty good overall, and esp. underneath - the batteries hadn't
leaked (it had a wrong one bumping around inside), and the only obvious
damage is that the stop-pin on the loop broke, and the wires twisted off -
ouch. I can see myself having to open the loop and splice them ... bet I'd
have to drill out all ten screws ...
Help?! e
