From Gemini to Apollo with a Collins 51S-1F Receiver

As we were cleaning up equipment for photography and testing, KFØCOM discovered an original JPL/NASA DSIF (Deep Space Instrumentation Facility – pre-Deep Space Network) tag! It was affixed to the reverse along with a green and white inspection/calibration sticker with JPL stamp and handwritten dates 1/17/68 and 10/8/69 with “JPL 17” and “JPL 168” code stamps next to them – indicating this unit was in service during the heart of the Apollo program!
