[TowerTalk] Aluminum mast

[Tod Olson]

Stan:

I have sent my complete set of NCJ's to ARRL HQ for
conversion to a CD-ROM. I sent them in August. I was
scanning through issues as I was making certain that all
were there and believe that I saw the article you are
thinking of.

I have another set that I will check when my ARRL work at
the ITU Conference is over.

Tod, K0TO

Hi OM,

It may well have been published in the March/April issue of
1993 NCJ.  It turns
out that particular issue is missing from my files and I
can't check it to see.

Can someone else check it and let us know if it was
published in tht NCJ issue?
