Excellent observation, Don. I've been on that section of 40 meters
listening at night.
Ye, no free lunch on keeping/goingto a clear frequency, but it's almost
that way.
Gotta stay light on ye toes, ready to wiggle ya VFO, huh?
Note: The band conditions recently on 40 meters AM have been great,
haven't they.
