No matter the day, no matter the weather, no matter anything whatsoever, 5.332MHz is always distinctly noisier than 5.348MHz on the 60m band. Noisier by at 2 to 3 S-units. And with a distinct hollow howl, like listening to wind through the tube from a empty roll of toilet paper. So I'm wondering, is it thus with anyone else? Or is it only just me? Should I suspect my IC-745, or the local environment? QTH is just north of Holland MI, a quarter mile inland from Lake Michigan, across the lake from Milwaukee.
