[Test-Equipment] FS: Heath IM4180 FM deviation meter

[Mike Manes]

Hey George,

Get a copy the ARRL Handbook - even an old dog-eared one from a hamfest -
and browse thru it a bit at a time.  It's probably the best all-around
tome on radio and electronics theory and practice ever published.  It's
often cited as a reference in academic papers, and what I learned from
it as a kid got me a scholarship to a name-brand engineering school.

This hobby offers a lifetime's opportunity of learning, and that's the
bit that's kept me active in it for 48 years.  Who knows? By and by,
even you will get to the point of Elmering some younger new hams as
well!
