Intriguing premise, to convert the digital information to analog and view the resulting pattern/scope curves taken from the IF strip. I have here a bunch of monochrome analog TVs which, when tuned to UHF 58 or UHF 82, display sporadic flashes of digital data in the form of lines and dots.
These must be cellular or perhaps experimental WiMax type networks. Not sure how far the WiFI-blanket networks have progressed since their inception. I do know, of course, that the old UHF analog TV spectrum has been sold in part to the cellular companies & to government entities using it for first-responders.
UHF 58, by the way, is held in high esteem by paranormal investigators. Evidently, Albert Einstein was quoted as saying that it was possible to slightly de-tune a television receiver backwards from the center of 58 to conduct investigations with e.v.p. A germanium detector diode would be connected to the UHF tuner via a whip-type antenna 18" in length.
Taken with a grain of salt, this experiment would be largely impossible nowadays with digital garbage being beamed at these frequencies.
