This is an interesting topic and the explanation I saw on it some time back made
perfect sense.  However, I also find it interesting that I have never
experienced the ticking at all on mine.  Over the last couple of years, it has
had a nice workout almost daily on six meter digital modes, where it heats up to
stage 4 and sometimes 5 on the fan, and it has never done it.  Even before that,
when it was newer and was only used on SSB/CW (stage 1 and sometimes 2 fan), it
didn't do it.  I'm curious why some do and some don't???
