Radials do have standing waves, and so the minimum impedance at the base

I can understand why people are upset about this. But the reality is that
no matter how upset we decide to be about this sort of thing, it's simply
going to happen more and more.
There's some truth to the saying, Don't worry, be happy. :-)
The rest of us can operate our stations the right way.
The contacts were not made via the internet, they were made using a radio
controlled over the internet.
I operate my home station every day using a computer in my office from 70 miles
away over the internet.
It's no different than sitting in front of the equipment.

Well the same thing is going on with the Olympics. Steroids are supposedly

Eventually the use of steroids will be accepted because the regulators fail.
Same thing with ham radio. New ways to cheat are evolving, are being

Many remotes use K3's with one of the radios being another K3 or scaled

Not only that, but it defies logic that radials would NOT exhibit the same

current. The boundary condition is near zero at the end ( near because
of capacitance at the end). Rudy Severns, N6LF, has explored this in his
