      It’ll pick up autofocus of a digital camera and spark plugs firing in a gas engine. Not a joke. They have a chart showing the camera signal (some use a radio signal) and all vehicles on campus are diesel. No cell service is allowed in the valley and they have to approve towers in a 100 mile square. It’s pretty serious. It also great for incredibly dark skies, for the astronomer in you.

      GBT receivers provide nearly continuous frequency coverage from λ = 1 m to 6 mm (0.29 to 52 GHz) with on-sky system temperatures as low as 20° K. A single-pixel correlation receiver for λ = 3-4 mm (68-92 GHz) and the Penn Array 64-element bolometer camera for λ = 3 mm (100 GHz) are under construction. The GBT spectrometer is a multilevel digital correlator providing 2,048 channels in each of eight 800 MHz spectral bands or up to 262,144 channels at 50 MHz bandwidth. The Zpectrometer, a redshift machine for the GBT having a 14 GHz instantaneous bandwidth at 26-40 GHz, has been funded by the NSF ATI (Advanced Technologies and Instrumentation) program. Three fast-sampling backends provided by university collaborations are available for pulsar observers.

        With frequency coverage from 0.29 to 52 GHz and a system temp colder than my ex’s heart at 20 Kelvin, the GBT could probably pick up the Playboy channel’s quantum echo from the edge of the universe. But unless those 64 bolometers are tuned for late-night static, you’re outta luck, champ. This baby’s built for star stuff, not soft stuff.
