Yeah, heard that one, it was an Earthy glitch that caused that loss of data and it was the clever design of Voyager that it will move its antenna back to more or less be able to latch on to Earthy signals which it did when we more or less shouted RF in its direction.
It is mind boggling we can do that at all, considering it is some 20 billion odd km away from Earth and many hours of just the journey those radio signals take to get there and calculating how far away it is, and how much it moves and how much movement Voyager would make to be out of the radio beam, pretty awesome for 1970's technology.
It was pretty awesome to me personally to be part of Apollo where my job was Apollo tracking and timing, a small part of it for sure. Tracking was a transponder on Apollo that spit back a special digital signal radio'd up to Apollo and when the signal got back to Earth comparing the digital signals of sending and receiving told how far away it was within FIFTY FEET, and if they wanted to bad enough they could have tweeked that bit to be within 6 inches but within 50 feet was more than good enough for that era.
The timing bit was atomic clocks used to be able to coordinate the changeover from one radio dish say in Austalia ( where the 'one step for man' bit was actually picked up from, to one say in Chile or somewhere else because ALL those dishes lose contact on a regular basis since the Earth has the habit of turning those dishes away from Apollo and so the atomic clocks were used to generate timing pulses that allowed say that Aussie station to switch say to some dish in Chile within 100 NANOSECONDS, if they got that kind of accuracy in the switch, no data to and from Apollo would be lost.
Great gig till Nixon got ahold of it🙁
