Topband: RFI on TB

[Brian Campbell]

You can put me in that group as well. Here are just two recent examples.

VE3MGY 2018 ARRL 160 -1001 QSOs - QSOs Received on TX antenna alone - 996 (99.5 %)

VE3MGY 2019 CQ160CW - 938 QSOs - QSOs Received on TX antenna alone - 930 (99.1%)

I usually run diversity in which case I will have a couple of beverages,  Inverted V, or loop in one ear to choose from and the Inverted L in the other ear but if it's relatively quiet on the L ( S1-S2 ) I will just stay there at times. I needed RX antennas more at the previous two QTHs but here not so much ( at least not yet... ) In any case every QTH is different so YMMV...

73,
Brian
VE3MGY

I'm with you both, never rule out your vertical!

During one ARRL 160 contest a few years ago, conditions were such that I
used my inverted-L over 90% of the time *even though I had two 580'
switchable-direction Beverages*. Signals at my central USA location were
coming in from all directions.
