[syndicate] beacon, cb

[Alan Sondheim]

beacon, cb

the earlier crystal radio files have been taken off.

the first file below is from crystal radio with a cb radio transmitted
coupled to it (the transmitter antenna rod placed near at right-angles
to the loose coupling coils). the recording was (as with the other files)
through a sony minidisk connected directly to the crystal radio output.
sounds are breathing through the cb, turning it on and off, etc.

the following two files are highly modified, direct from crystal through
minidisk; if you listen carefully you can hear a low-frequency beacon at
one point.

with all three files, the variometer is used for fine tuning (in series
with the loose coupler primary; the other end connects to ground).

why are these of interest? for me, it's the mystery and wonder of coil
couplings against power grids and human transmissions. and then what
happens!
