Just wanted to thank one an all for replies to this. I will be keeping an eye on these two systems and as I figure out how to get them more stabile I will report back. One thing Bob Mair pointed out is that RH variance of this magnitude is not neccessarily a problem.... if the moisture content in the panel remains stable. Immediate symptoms of the lack of this is less then expected tuning stability... which seems to case here. Anyone got a line on some gadget that can monitor this moisture content directly over time ??? -- Richard Brekne Associate PTG, N.P.T.F. Bergen, Norway
