Topband: Fishing beacons redux

[N1BUG]

An observation: There seem to be more LOUD buoys this season than 
ever in the past. I wasn't on much last season due to local noise 
but it seemed to me activity on topband was WAY down from the past 
several years, perhaps due to people going back to higher bands. 
Could the two be related? Less amateur "QRM" makes 160 a more 
attractive place for buoys? Just wondering...
