I just bought a used Ham-M rotator last week. This is the "old
version" with the brown bakelite control box with the single
lever switch. I am concerned that there is no brake delay for
this controller (not even a manual one).
Is there a web site somewhere that details how to build (from
scratch) and install a brake delay circuit for this rotator?
Would putting in a brake delay make it unnecessary to add the
"torsion bar" recommended in the Ham-M rotator manual?
Also, is there a web site anywhere that shows how to construct
and install a PC interface?
In general, are there any other web sites which detail home-brew
mods to the Ham-M rotator?
If I were to add a switch into primary of the motor/brake
transformer, or switches into the motor and/or brake circuits on
the secondary side, what should be the contact ratings for such
Note that I am interested in completely home-brewing my own mods
to the rotator control; not purchasing a commercially available
