Hudson, WI -- 3 x 64QAM Channels?
Maybe they have found your upstream is clean enough to allow 64QAM on the lowest frequency.
There was a previous post from Tobin
in Hillsborough/San Mateo, CA that showed three 64QAM channels plus a 16QAM one: »Hillsborough/San Mateo, CA
Squeezing 4 QAM carriers into the upstream is a big challenge, see: »4 Upstream Channels
