Is there anyone who worked for or knows about Radiation, Inc. ground support equipment? I have many modules produced by them that appear to have made up a a very early digital computer (1961-62). I also have one of the wire wrapped fixtures that the modules plugged in to. I would really like to find out anything about this system. I purchased these modules as part of original lot of over a ton of Apollo hardware in 1976. Thanks,

Jim

Radiation developed the CM Pulse Code Modulation (PCM) telemetry system. They transitioned to Harris Corporation (Government Systems) ~ 1967.

Hi Scott,

Thanks , do you know of anywhere I could find out about the GSE they built . I have been in touch with some people at Harris who say they were there during Apollo. They couldn't remember the equipment I described .

According to this extract from SP-4009 the GSE segment (Decode/Process) of the PCM architecture was built by a different company (onboard spacecraft components were developed by Radiation). Its possible that either Dynatronics/Sperry subcontracted Radiation for portions of the GSE segement:

December 17 (1964)
NASA announced the selection of two firms to supply electronics equipment for the Manned Space Flight Network:

1. Dynatronics, Inc., to design and manufacture pulse code modulation (PCM) telemetry systems. (The main function of the PCM system would be to decode, or as the NASA news release put it, "decommutate," telemetry signals from the spacecraft). Dynatronics' contract would be worth an estimated 3.5 million.
2. Univac Division of Sperry Rand, to furnish data processors. (These machines, as their name indicates, would process those signals received by the PCM system. This information then would be transmitted to the Mission Control Center at Houston. The value of Univac's contract was placed at $4.5 million.

NASA News Release 64-318, "NASA Selects Apollo Data Contractor," December 17, 1964.

Regarding "Radiation developed the CM Pulse Code Modulation (PCM) telemetry system"

I'm most interested in the CM PCM hardware. Has anyone identified any additional sources of info (since the last post) for Radiation, the hardware, or its integration into the CM?

Thanks much. Tim

The Apollo Operations Handbooks (telecommunications section) have detail discussion of the PCM functionality and architecture on the CM. If you are unable to source online, I would be happy to email an extract.

Thanks Scott,

I would greatly appreciate any info you might have. I'll email you direct with what little documentation I've found so far, and some description of the PCM hardware I'm researching.

Thanks again.

Tim
