Vintage G-1013 HF receiver from the 1960s

Has anyone encountered info on specs and external appearance of the "G-1013" HF receiver from the 1960s? It was used in the late 1960s in Nam for monitoring HF nets, also from airborne posts. Which company made that receiver?

Doesn't ring any bells. How big, what color, built in speaker or external, what frequency range, display mechanical or digital, what modes (AM/CW/SSB)???

No further info known, alas. Only that it could have been used in conjunction with the G-1099 panadaptor and the G-1003 direction finder. No photo found so far.

G-133 series maybe?

You might check receivers by LTV, Astro Communications Labs, Airborne Instruments Laboratory, Aiken, Norlin and a few others that slip my mind. They all made airborne receivers for spook projects from the 1950s through about the 1970s.

You're right that the "G-" initial would suggest LTV's involvement. Nevertheless, I initially thought that the set could have been made by Nems-Clarke or Microdyne. Due to the scarcity of documentation on the full range of black radio products, as of now, it's still difficult to ascertain the origins of the G-1013.

You may have seen some aircraft paperwork previously marked SECRET mentioning the G-1013 so it may not have much info available.

Indeed. Apparently it was used on the recce versions of the C-130A/B in Nam. Do you happen to know if other aircraft types were also fitted with the G-1013? Maybe that would streamline the search for information on this highly obscure receiver?

I've only dabbled in mil aircraft spook receivers and don't know what aircraft they were used in.
