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

[Nick England]

Oh the Navy had zillions of R-390A's with the TMC CV-591A SSB
converters - often two CV-591A's so they could run ISB.

Also many installations had the National synthesized monster AN/WRR-2
(shipboard) or AN/FRR-59 (shore). Their level of stability was needed
for AN/UCC-1 VFCT multichannel RTTY signals with 85hz shift. I suspect
the SRR-15 was a development contract for what became the
WRR-2/FRR-59.

The RCA SRR-16 was quite different - a modified SRR-13A

All these got replaced by R-1051, of course.

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.
