![]() ![]() ![]() There is no telling how many other prints were made from the original drawing.īe aware that what you have is a blueline print.ĭoes that leave a smell or does the smell due to the age of it? Either way it is very cool. A bright light exposed the paper and then it was "developed" with an ammonia based chemical. It was then fed through a machine in direct contact with a photo sensitive paper. The original drawing was probably done on a vellum material. This link might be helpful: Traveling-wave-tube amplifierīeyond that, I really couldn't say what the bigger-picture system was doing with certainty (and I'm not even 100% on the TWTA guess) but maybe a satellite transponder?īe aware that what you have is a blueline print. ![]() The rigid waveguide flanges would be consistent as a TWTA is a high-power RF amplifier device that would generally interface by just such a means. TWTA stands for Traveling Wave Tube Amplifier, and perhaps yours was a different band (Ka?), thus the slightly different drawing number. Your drawing number (10064020) is closest to the X-Band and S-Band TWTA Sub-assemblies ('21 and '22) listed in the JPL doc provided to you. JPL also designs a lot of microwave systems never intended for flight application. However JPL has deployed X/KA band on robotic missions that do incorporate waveguides. ![]() Without specifically addressing the blueprint, correct - relatively low frequencies and short transmission distance obviated requirement for rigid wave-guide on M/G/A. The above has a good chance of being wrong in whole or in part but shoot me the full album link and I'll give it a look. Looking at Scott Schneeweiss's website () I don't see any radio hardware for Saturn, CM, or LM that utilize hollow, rigid RF waveguides (all connectors seem to be coax cable only) but he can best address the nature of all radio "plumbing" used in Apollo.Īdditionally, JPL's involvement with Apollo was mostly around development of Ranger and Explorer robotic probes to my knowledge. Waveguides are high-power / low-loss, but also high-weight RF signal carriers. There also seem to be flanges for mounting of rigid waveguide tubes, the latter suggesting - to me - ground-based RF equipment. are implied by the SMA/coax assemblies shown. Radio Frequencies (RF) in the microwave regimes of X-band, C-band, L-band, S-band etc. The 'Diplexer' mentioned usually corresponds to frequency-selective splitting, either for Transmit/Receive (Tx/Rx) separation within a band, or for multiplexing individual bands/channels (Tx/Rx or Rx-only) into a common signal. I did and will post what I find out when they get back to me.įrom the limited amount I can see/read, it would appear to be part of a radio transceiver. Well I sent a FOIA request to JPL and they suggested I contact JPL Public Affairs Office and the NASA Headquarters Public Inquiries Office. I can include a link to the album which has more photos if needed. It is dated May of '66 so I think I could have to deal with Apollo. I will upload scans of those if needed and if more photos are needed I will upload those as well. The only thing I know is that it came from an estate sale of a NASA engineer. I am 99% sure it is the original and it came with what I think is the part sheet. Last week I bought this off eBay because it just looks cool.
