I did some work for the UK company which came up with the original 
system which, I think, EFJ marketed in the US. 20odd years ago 
5kHz channel spacing and a whole trunking system in a single 25kHz 
channel seemed way ahead of the field.

I'm interested to know why you refer to it as 'junk' - was it no 
good in practice?
