[aprssig] TAPR Dayton Solar Talk

[Greg Dolkas]

Are you suspecting low voltage?  No, the whole room is on the same breaker,
and my UPS shows a nice steady 118v coming in.  No flickering lights,
either.  Should be good in this department.

My belief is that the &^%$@ ceiling fan vibration is doing them in.  This
would be consistent with standard bulb being worse than the "Appliance" or
"Fan" varieties.  And also consistent with poor mechanical support and
soldering reported earlier.  These fans are "Hampton Bay" models form Home
depot.  On sale, but should have passed them up.  The master bedroom is
immediately above the Shack, and I can't run the fan late at night if my
wife goes to bed before I do, because of all the buzzing.  Exceedingly
annoying in the summer.
