I've seen advertisements for several magazines -- popular
communications and another US one as well as some UK magazines.

Is it worthwhile to get a subscription to one of these? If so, which
is best?

I get Monitoring Times. The SW guide makes Passport less valuable. For me,
MT is probably better value. Passport is more of a reference guide,
helpful when starting out. MT has ongoing interesting little bits of
things.
