Emily Lakdawalla's blog on The Planetary Society has an article on the details of communicating with New Horizons.
Pluto is far away—very far away, more than 30 times Earth's distance from the Sun — so New Horizons' radio signal is weak. Weak signal means low data rates: at the moment, New Horizons can transmit at most 1 kilobit per second. (Note that spacecraft communications are typically measured in bits, not bytes; 1 kilobit is only 125 bytes.) Even at these low data rates, only the Deep Space Network's very largest, 70-meter dishes can detect New Horizons' faint signal.
The article goes into some of the tricks used to improve the data rates and keep within the spacecraft power budgets.

A pity that it's totally undeserved.

I hope they don't just scrap them; they'd make great radio telescopes.

Radio telescopes? Yeah sure, but how about a parabolic solar death ray instead? Much more fun...

Sweet! That way, when Cleolanta of Ophiuchus or Ming the Merciless of Mongo show up trying to move in on our prime lunar real estate, we can just push the button and "Poof!". Rocky Jones and Flash Gordon can sleep in.
