Twitter has tracking posts for both the DSN and the Voyagers themselves.
there is a phase for every operation with the voyagers as Jim describes,
followed by data transfer (for instance lately 159b/s)
DSS 14 carrier lock on Voyager 1
Frequency: 8.4199GHz
Signal strength: -156dBm
OUT OF LOCK OFF 1 MCD2
DSS 14 receiving data from Voyager 1 at 159b/s.
IN LOCK OFF 1 MCD2
@NASAVoyager
is 21 hrs 03 mins 24 secs of light-travel time from Earth
(2020:333:120000:1L)
@NSFVoyager2
I am currently 17 hrs 28 mins 57 secs of light-travel time from Earth
(2020:333:000000:2L)
My favorite part of the JPL tour (Mission control) is the live status of
the Voyager spacecraft. They've been on Twitter for years now.
thanks
Jim

A good part of the "art" of communicating with an "old" spacecraft is
knowing/predicting/guessing where the "best lock frequency" is,
because DSN sweeps very slowly through that frequency hoping the
spacexraft receiver acquires it in a <10Hz BW filter. If you don't
see the transmitter frequency (in turnaround mode) jump when
acquisition occurs, you widen up the sweep, or slow it down, or turn
up the exciter power.
