[Spooks] Need some help...

[Todd Dokey]

Read "Uno Dos Cuatro"  by Havanna Moon, followed by Simon Mason's book (both online) and the newsletters mentioned on this list.

Then do some listening too.

Havana's mysterious clicks are the hold generator that flash the lamp on old 1 A2 key equipment. Hint: AT&T longlines.

But I digress...
