Fw: [Milsurplus] GRR-5 vs. R-392

[windy10605 at juno.com]

Ray,

They are nice SW listener sets and this is what the manual says:

-----------------------------------------------
"Purpose and Use
Radio receiving set AN/GRR-5 is a mobile radio receiver used for tactical
purposes. The radio set provides facilities for operation either with a
loudspeaker, contained within the unit, or with headset CW-49507-A (Navy
Type), connected externally, or with both loudspeaker and headset.
Radio receiving set AN/GRR-5 is capable of receiving AM or CW over a
frequency of 1.5Mc to 18Mc. The equipment is intended for use in a
fixed-field station and for mobile operation. The operating components
required for normal operation are shown in figure 4. The power
requirements are 115 volts AC, 6 volts DC, 12 volts DC, 24 volts DC, or
dry batteries (90 volts and 1.5 volts).

System application
Radio receiving set AN/GRR-5 may be used alone as a conventional radio
receiving set, or with an appropriate AM transmitter in a particular
communication system. Figure 2 shows its application as an
antiaircraft-warning receiving set in conjunction with Radio Set
AN/VRC-8, 9, or 10 and Intercommunication set AN/UIC-1."

Although the subject has been beaten into the ground before I still am
curious, what was the original intent and deployment of the GRR-5? The
broad tuning, lack of standby function and no IF filter show this not to
be much more then a repackaged GRC-9 receiver and with the internal
speaker, multitude of power options and preset channels it almost appear
more along the lines of a moral receiver, except it dose not cover the
entire AM band. Before anyone say anything I do know that a GRC-9 only
covered 2-12 Mc and the GRR-5 covers 1.5 -18 Mc , but look at the tube
lineup and controls to me they have more in common then different. When
was the first deployment of the GRR-5 series? When were they withdrawn
from service? They look a lot like they belong with AN/VRC-10 family of
radios and less like equipment that was in use in the mid to late
sixties but I have several first hand accounts of its use in Vietnam.
The R-392 receivers that were in abundance in Vietnam were so superior
for AM and CW operations that I would speculate that no one would use
the GRR-5 for serious communications work. Was their a transmitter
intended to be used with the GRR-5? , The R-392 was always paired with
the T-195 in the AN/VRC-19 but cannot picture a GRR-5 with anything.
Other questions about the GRR-5, is their any radio with the exception
of the GRC-109 with as many power options? Where they at any point in
production at the same time as the R-392? And what was the cost
difference? Yea, I know that the 392 cost more but with all the stuff
jammed into a GRR-5 they could not have been cheap. And on the subject
of moral receivers, was their a military purchased radio available in
Vietnam for troop use?
