[Lowfer] 3rd nite Waterhole

[Lyle Koehler]

Another good night, Lloyd! It's interesting that of the Minnesota 3, BRO was
solid during the entire capture, but WEOH faded out as LEK was fading in.

LEK was using the $20 AT90S2313 development board from Futurlec (with its
original 8 MHz crystal) as the exciter. During the night the temperature in
the shack dropped about 10 degrees F, and it looks like the frequency
drifted upward by about 0.25 Hz. A 74HC14 IC provided the "dot clock" for
the development board and served as a buffer to drive the coax going to the
final amplifier in my garage.
