Re: [TowerTalk] nice trick for raising masts to drop into a tower

The editor of the FRC newsletter has already received permission to reprint 
it in their Newsletter.  As long as credit is given to K4ZA and the PVRC 
Newsletter, clubs should feel free to reprint.

By the way, there is a picture of the device in the PVRC Newsletter.  The 
security on the server we use for the PVRC web site will not permit direct

scroll about halfway down, you'll find a link that does work.  The article 
(and picture) are on page 4.
