  On Topic: I am reminded by the "RFI" from open machines thread, of the
tried-and-true early computer music method of simply placing an AM
Broadcast reciever next to one's Box and then diddling the various
registers, front panel displays, etc., until the tones generated by the
RFI made the 'music' patterns in the radio's speaker.

  This was also echoed in the many compositions for various line and
dot-matrix printers, and the obscure but maybe better known theme music to
NPR's financial program (Wall Street Week?) [Louis Rukeyser] which used a
tape punched to make an ASR33 do a repeating pattern and the resulting
sounds recorded and used as the rhythmic basis for it, the which music was
called TWIX in Twelve Bars. (composer name escapes me completely)
 

  Off Topic: Shortwave radios. I have gotten hold of an ICOM PCR-1000,
which is the actual 'radio' parts of a modern full-coverage receiver,
minus the front panel. One uses various programs on a PC.laptop, or Mac to
'run' the unit. Since the operation is computer-based, many possiblities
open up that were before only the province of agencies and *really*
dedicated radio-heads. It covers 100KHtz -> 1.3GHtz continuous but for
the Cellular bands, which are blocked. It is the size of a small book and
wieghs a pound, runs on 12VDC. Just add antennae....
