Re: Ads for ESSCO RTTY/TU Products
I looked through my binder of 1967 73 Magazines, and found an ad on page 129.
It must have been the one that caught my eye since I see some scribbling on
that page with some prices, and a likely total that I'd pay for the package.
I won't say that there were no other ads in the other 1967 73 Magazines, since
I was doing my 'looking' in dim light. If anyone really wants to know more, I
will look in the 1968 binder and see what is there. I would not know how to
place such a scan onto an internet page, but if anyone else can do it I can do
the scan and e-mail it to them for placement.
73,
Ralph - W8ROI

Tips to keep private email addresses out of the hands of spammers:
1. Avoid giving your or anyone else's email address to any web site.
2. Instead of forwarding email, copy and paste the text.
3. For group emails, use the "bcc:" (Blind Carbon Copy) field instead of "To:".
(Put your own address or a fake address in the "To:" field).
4. Want to do more? Attach this text as a custom signature to the
bottom of all your outgoing email.
5. Delete any visible headers in the text window.
