[TowerTalk] (another)Problem That Needs Ideas

[Chuck Dietz]

I have been using 24 volts on 12 volt coil relays for years and I have never
had a failure.  Occasionally I have left a switch on with a relay energized
for as long as a week.  The higher voltage also compensates for resistance
in the lines to the relay too.

I have a two port six pack that I have relegated to the back bench because
of relays not always pulling in.  It is tough on amplifier tubes to be
running into an open!  My rotator has no  brake, so cannot try that method. 
A very light touch on the offending relay always makes em pull in however.
