Dave,

As it turned out, there were only two peaks that permitted any copy.
Unfortunately, I goofed and didn't capture all of the first peak. It did
show part of the "Y" and the complete "XM." Here is the section that WAS
saved:

A later capture on a 60 second screen again has the "XM":

This qualifies for nothing, but is interesting to illustrate the duration of
the peaks. No other signals were seen, though it looked like something was
happening on 135923.0 several times.
