GreenKeys gang:
I discovered that the switching/relay article will be found on Disc 5 of the
RTTY
Journal Archives,
or more to the point, in Volume 31 #6; Pages 17 and 5 .
For some strange reason, it starts on 17 and finishes on 5!
I've printed out those two pages and can scan them for transmission
if anyone is interested.

(My call back when I wrote the articles was WA8GDT)
