The GRC-3030 is a nice design for the era it stems from. Though built in one case, receiver
and transmitter are separately tuned - and indeed this is a common denominator
with the GRC-9. As it is fully tubes, it has it's dynamotor power supply.|
Quite different from other designs I know from it's period is the approach where a separate crystal calibrator is actually part of the system. It reminds me of older sets - but even there, these crystal calibrators were not a permanent part of the system.
The GRC-3030 is definitely geared to vehicular applications. One
could hardly call it portable - well, a two man lift at
best. Sometimes it
is dubbed the Dutch version of the GRC-9, but I do differ to disagree, if
only on these grounds. The GRC-3030 is by it's weight and construction meant to be vehicular, I'd say.
The GRC-9 can - and was - used as a man pack radio. It even had a backpack.
Also, the separate audio junction box seems to be a special development, at least one I have not witnessed elsewhere.
Five main parts:
No known intercom system...
