Ed, I completely forgot to discuss the reception of the Lunar 
orbiter. Yes, we used an old TS-408/U (military version of a hp 608A 
signal generator) a polaplexer, and Bill Burns 8-foot trailer mounted 
dish. We got good S/N ratio on the carrier, but couldn't recover 
information from the sidebands. If I remember correctly, the downlink 
was about 2287 MHz. The downlink/uplink ratio was 240/221, Milt 
Brockman's ratio we used in the DSN since the L-band days.  73, Dick K6HIJ

So there you have it.
