which but it may have been Voyager - for the omni antenna, was only 40
bits per second. And that was really difficult to dig out of the
noise, requiring cyro cooled receivers and integrators to get rid of
the noise. And the high gain directional antenna was something like
1200 bits per second, again with great receiving difficulty. Usually
the ground based receivers required a huge dish like the ones at
Goldstone. Hey, you'd be a weak signal, too, if you travelled a
couple hundred million miles!!

gave them. The fallback mode data rates were 32 and 7 bits per
second, but I read that they are now comm'ing at 120 bps. The direct
to earth xmissions were between 3500 and 12000 bits per second.
Here's an article about it.
