CB to 10

[Lewis c Emerson]

Hi Mike,

Many thanks for this info.  I'm not familiar with the book, but do
remember that one of our Ham Radio Mags carried a series of articles on
the conversion steps - pretty simple as I recall.  I think it was 73 Mag,
but could be CQ one of the others.   My memory just work any more and
without those mags I can't look up the articles.

I gave away a 60+ year collection of my QSTs and many years of CQ, Ham
Radio, 73, etc. so however, I do remember to whom I gave my mag
collection to so, if any of you out there, can tell me which mags and
which issues had those articles I'd be most appreciative.  I than can ask
my friends, who have my collection, to lend me back those issues.

I bought these boards about 20 or 25 years ago thinking that I'd give a
mobile 10 meter FM rig to each of my  children, but they were not at all
interested - so I'll see if the grands are interested and if not, I'll
put them up for sale here in case any of you are interested.  I paid
something like $10 each for these back 20 or 25 years ago so they are
cheapies.

Several decades ago early 10 Meter FM pioneer: Bob Heil [K9EID] published
a conversion handbook on this very subject and model radio (Cybernet)
titled:
"10 Meter FM Handbook"

If you go over onto the 10 Meter FM YahooGroup 
< http://groups.yahoo.com/group/AR29MHz-FM/ >, you will see a photo of
K9EID holding one of the radios after the conversion and a copy of the
book.

Copies of the book can still be found on eBay from time-to-time.
