Mystery of Gain of 2 Solved
MIKE has had a gain of 1/2 of that of TOM. I stared at resistor bands
until I could not see straight then I got a magnifier and stared at them
some more. Finally I noticed that Dan had put the damping network on the
back of the board as a parallel 100 ohms and 100 pf instead of a series
damper. This loads down the 100 ohm source. Sigh! One more thing fixed.
My theory on the junk data problem is that something is getting wet when it
gets humid late at night. I guess that is why Arne does not see it. It
never gets to 100% in AZ. I think the relative humidity is below 100%
there even when it is raining? I think this is possible.
OK, I can find things that get wet, and even things that cause problems
when they get wet, but I cannot explain yet the junk data.
