[Milsurplus] Mystery Receivers AN/SRR-15, AN/SRR-16

[Francesco Ledda]

I have 3 WRR2, and I use them all the time. After messing with them with 20
years, I can say that the weak point of the WRR2s is not the radio itself,
but the alignment procedures made for the inadequate test equipment of the
time.  Aligning the HFO is not easy with the method provided in the manual.
Same thing for the synthesizer and injection amp. I feel sorry for the tech
that had to do that job...

Once these radios are aligned, they work for ever; of course, my house is
not rolling and bending like a boat in the middle of a typhoon...

The Navy also used FRR-60s on land. But a good control operator could keep
an R-390/CV-591 on freq well enough to copy 16 channel MUX. For voice,
besides the 390s, shore stations also used KWM-2s. The FRR-59 was a bear to
operate. We just started seeing them in 1967, and they spent as much time in
the hands of the ETs as in our hands. Thje 390s and 1051s were much
preferred.

develop a replacement for the R-390, the whole SRR-11/13 line were dogs
subject to drift and service issues like the cast crank levers. Would
speculate that the SRR-15/16 were versions of the 13 with SSB capabilities
like a product detector and ability to apply AGC in SSB mode but would take
a stretch to facilitate ISB operation in that chassis due to the addition of
everything for second audio channel. It does bring up the question of what
did the navy use before the introduction and distribution of the R-1051
family of receivers for SSB operation.
