[Milsurplus] Wideband Receivers R-1039 and R-1151 ???

[Nick England]

I'm reading a NSA report about magnetic recorders for SIGINT.
https://www.nsa.gov/public_info/_files/cryptologic_quarterly/NSA_Signal.pdf

It references R-1039 and R-1151 as receivers with two 100kc bandwidth
outputs feeding some recorders. Probably means R-1151/GLQ but I can't
anything about R-1039/??
(Can't find out anything about R-1151/GLQ either for that matter!)

Does anyone know anything they are willing to share?
