Hi Jim, Is there a possibility that your wiring has enough
resistance/voltage drop to cause a loss of horsepower? Is see on the Hygain web
site that
the higher the voltage, the higher the turning torq.
Considering the large number of these units used in Europe at higher
latitudes than yours without reported problems with the grease it seems
unlikely
that is the actual cause of your problem. Sure the grease does get stiff
when cold but one would expect the motor to be able to deal with that.
The description I read showed operation from 12 to 24v either AC or DC.
Perhaps you could do a test from the shack with a voltage source connected to
the motor leads only to see what happens.
Happy hunting!

My RAK-1 refused to budge this winter when temps dropped below zero
Fahrenheit. It began working one the temps warmed to above 20F. Since it
was always below freezing when working I don't think it was icing.
I think the grease used for lube just got too thick for it to work.
What would be a more suitable grease to prevent this?
I could also put some sort of heater on it as a last resort but that seems
a bit much.
QTH is Parkton, Maryland, due north of Baltimore and just south of PA so
this is a infrequent but annoying occurrence especially during a contest.
TIA
