Topband: Preventing QRM

[wa3mej at comcast.net]

Brian, 

I currently have a very high power line noise (the electric company is trying to find it) that is why I mostly use a techique I call scan and pounce (at my age I cant pounce too hard though) whereby I listen for others to call CQ and pounce on them.  THis helps to eliminate some of the interferance on the bands.  In fact with the S6 raw AC signal in my inverted L... well I wouldnt even being scanning and pouncing without the new Beverage antenna.  I also use other resources out there like the reverse beacons and the PSK reporter and JT65 information on top band.  This allows me to have a more clear picture where to look and when to look there.  Oh before I forget try looking at what N4IS uses, I am guessing he doesnt have room for a Beverage but he still makes the best of what he has by using a Waller Flag.    www.n4is.com
