Topband: 160m Condx

[Richard (Rick) Karlquist]

A related issue is that frequencies ending in 0 and 5 tend
to attract casual operators who can't hear DX.  Many times
I have heard them start up and call CQ on top of DX.  I
like to choose a frequency ending in 2.5 to avoid the
casual ops.  On the high end of 40, this neatly avoids
BCB stations, and any decent rig can notch out the 2.5
kHz heterodyne.
