[R-390] R392 Condensation

Sun, 8 Jun 2003 17:51:45 +0100

Thanks to all thos who replied to my question...I have had the set out of
its case to replace the tuning lock, which some idiot had removed and lost
previously.

 The replacement came from Dan (Hank) Arney.....Thanks Dan!

I thouht the idea of running it up until it is hot and then casing it was a
good one, and that is in fact what I did when I re-cased it yesterday....It
must be more humid here than it feels, I guess!

Good advice from Bill W2CQ.....Perhaps the Equatorial region shopuld be
re-named as the boatanchor belt!
