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!
