Topband: Narrow Filtering

The importance of zero beating the station being called becomes increasingly 
important.  The art of zero beat is certainly not what it used to be. 
Compounding this with stations running extremely narrow bandwidths creates a 
lot of confusion and frustration.  When you add in excessive QRQ and 2 
seconds of listening time between CQs (or less), it's no wonder some big run 
stations miss a lot of Qs.  It's not exactly like running JA from NA on 10m 
in the peak of the sunspot cycle.
