[SMCARA] Bootleg radio really primative

[John Johnson]

1947; A classmate and I put together a radio communication system.

For oscillators, we employed old Model-T spark coils; no tubes;

Talk about broadband; we spanned the spectrum, exchanging early digital 
dot-dash pulses over a block and a half distance between us.

There was no television to interfer with back then; and AM-radio was always 
accompanied by some static. WLS, WBBM ,and WGN still got through. We did 
keep our transmissions short.

Altough we thought about it; we stopped short of building a rhombic antenna 
field.
We might have devastated the whole Northwest side of Chicago if we had.

We also tried a single wire, with ground return, telephone system the same 
distance between us.  using carbon granular mics and eletromagnet earphones.

We were never able to talk on it; but WLS came in loud and clear; no LCR 
circuits, no tubes, not even a cat's whisker and crystal.
