Topband: Preventing QRM
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 Jim WA3MEJ -- Message: 1 Date: Tue, 10 Jan 2012 15:25:58 -0500 From: Bill Cromwell Subject: Re: Topband: Preventing QRM To: Eddy Swynar Cc: kd6...@earthlink.net, topband@contesting.com Message-ID: <1326227158.3225.2.camel@lancelot> Content-Type: text/plain; charset="UTF-8" On Tue, 2012-01-10 at 14:42 -0500, Eddy Swynar wrote: > On 2012-01-10, at 1:43 PM, kd6...@earthlink.net wrote: > > > I run the risk of calling CQ on what appears to be a clear frequency and > > QRMing a DX station calling CQ or disrupting an ongoing QSO.

BK Hi, Everybody knows what QRM, QRN, QSB mean...those are NOT obscure Q signals. That's because they are with us ALL the time. We do the best we can to accommodate everybody else and fit ouir signals into the space available. Sometimes there are collisions. We adjust and keep going. 73, Bill KU8H ___ UR RST IS ... ... ..9 QSB QSB - hw? BK

Re: Topband: Preventing QRM
Brian, Join the Low Band Chat at ON4KST where you can get a good real time notification who is using which freqency for skeds or weak signal work. You can also let everyone know where you are as you may require to grab some signal reports.
