The description of the Zero-Point Transmission Relay Scoop, used in the dust brigade questline (I think) features the following...
"After a bit of tinkering, it's now a fairly effective zero-point transmission scoop, tuned to high alpha-band frequencies and with a low modulation retransmitter designed to work on the archaic shortwave frequencies at around six megahertz. Also includes dedicated radioteletype encryption and even automated voice modulation - It also collects ambient samples from other, higher band broadcasts, so the teletype noises should get drowned out with nice doomy metal from Gridstream."
now that... is freakin' cool
