Hi Rob,

The only clue seems to be that it would probably be a US or Canadian
design as 210 kHz is not going to be used for beacons in areas with
Long Wave broadcasting.
Coincidentally the only thing I could find with a 4.4MHz IF was a
reference to the Nautel NRB4 beacon receiver (US/Canadian Manufacture),
which does cover 210 kHz but doesn't use crystals!

Kind regards
Dave
