Hmmm, there is a robustness issue. Surely the numbers are well
copyable, but the last few words are not "be sure to say...."
That sequence is particularly interesting to DX-ers since
it gives the station id.

If you could upload the entire file it would be possible to
make a fair comparison. Conditions vary with time. Maybe the other
sideband is better sometimes?
