[BC] McMartin Receiver IC CHIP identification

[Jim Tonne]

Stanley:

> SOMEBODY ASKED ME FOR THE NUMBER OF A CHIP IN AN OLD MCMARTIN RECEIVER. 

Probably me.  When I was at Moseley Associates
we used McMartin receivers to pick up telemetry
signals from the transmitter.  They were very well
behaved little receivers.

The IC I was curious about was a ceramic chip
with the marking "MOB603" for the 10.7 MHz
IF and "MOB604" for the 67 kHz subcarrier.
They were high performance and ran slightly
warm.  

Just curious.
