[Premium-Rx] Looking for info - Applied SR-2153 rcvr.

[Art Lebermann]

I'm looking for info on an "Applied Communications" model SR-2153 receiver.
This unit has keypad entry, with LED readout, and frequency range of 20 Mhz
to 1.2 Ghz.  Photos are available, on request.  This receiver seems to be
in good working order, but I'm "flying blind".  Any info will be very much
appreciated.

Thanks!
