I've heard of all of those except the one about letting it sit on one set of 
coils.  Still trying to figure that one out and how it might be a bad thing.

You will find that everyone does it differently...some leave them on 24/7 
(which they were designed to cope with) and some turn them on and off.

Probably the only thing I can think of that is a no no is do not leave the 
radio on and in the "STANDBY" position.  Our line voltage is high enough 
these days to add a bit of stress but unloading the power supply pushes some 
of the components beyond their voltage limits.  I think the best thing you 
can do with the radio is use it often.

There is a case for thermal cycling being harmful to electronic gear and 
just leaving it on 24/7 might be better for it...but really it's personal 
preference.

Thought I'd throw an email out for a question. I'm new to the Collins line, 
I do own several boat anchors, and wonder what is considered the best way to 
run an R390? I have heard, leave it on 24/7, ovens off, don't let it sit on 
one set of coils, frequency, when I'm not listening to it, shut it 
off........etc. What kinds of experience have any of you had that works?

Thanks in advance!
