Robust maybe but hardly speedy further out.
Here are some bit rates from HORIZON space craft:
Jupiter Flyby - 35 kbps
Pluto - 2000 bps

The bit rate drops to hundreds of bits/second further out.

Digital tends to be either perfect armchair copy, or fairly unusable.
It's going to depend a whole lot on how it's encoded, the data rate,
and how much error detection and correction is used.
Bump up the data rate, do some forward error correction and it's
likely to be fairly robust. Some of the methods used by NASA to
encode signals from deep space probes are incredibly robust.

Is anybody addressing the issue of QRM from other stations? I
suspect digital will fold -- especially when one is trying to detect
one out of many or a station immersed in splatter from one or more
stations.
