Topband: Skimmer calibration

[Tim Shoppa]

I quickly noticed that some skimmers seem to have more effective antenna
systems than others.

More than S/N, I look at kinda the breadth and depth of where I'm spotted.
On 160M, GW8IZR and DL1A are where I'm first spotted. If I'm getting
spotted more broadly or deeply than that, then I know conditions are really
good.
