[TowerTalk] any source for a GA-3000 ???

[Missouri Guy]

I'm pretty sure there was an article in one of the mags,
maybe QST or Ham Radio, that described a relay with a timer circuit
that would allow about 5 seconds before the brake would 
be released.   Later, a "board" was marketed called D-lay-5,
(something like that) that could be installed in a rotator control box.  
I installed a similar circuit in my CDE box years ago.  The beam
rotates, comes to a stop and then the brake is applied.  Works
great!
