[160m] BCI cause

[Tom Rauch]

As general information, I just learned the spurious signal was caused by an
unknown problem in one of several power output modules in a brand new
transmitter.

The only indication there was a problem, other than the spurious signals,
was a "drive" LED was not lit on one PA module.

Hopefully this won't become a big problem in the future. It took several
mornings of listening to identify the transmitter. It was very fortunate I
could hear them on 1390 enough to get an audio match.
