4QD isn't that frequent a visitor here Todd, but they were heard here
this morning with audio, among the 1550kHz splash.

They are about 10 Hertz high from 1548.000kHz, and some people can 
hear the difference in the BFO pitch, especially if you tune say to a 
200Hz beat note, then check a channel that is dead on frequency for comparison.
best wishes,
Nick

Using the best of my Modified 2010, I was able to listen to a carrier using
LSB. Signal was in from approx 1320-1355. Carrier was in with slow fades,
then steady and a choppy fast fade in and out then gone. 4QD is the most
obvious suspect.
