I thought it was also kinda neat that it was a few days *before* the 2009 ARRL CW DX Contest, in case any of us had residual TVI on the low VHF TV channels. Yes, sitting up here in the frozen north (

I have had DSL service from Frontier Communications here in the remote wilds of upstate NY for about five years. Prior to this summer I had arrived at a tolerable "truce" between my legal limit 160-m

Yes, that's pretty much the general direction I'm hoping to convince the telco guy to move in, given that everything else I've tried so far hasn't quite made the grade. Unfortunately, we've been "enj

I have a few here. To my mind, the 1500 VA units are barely sufficient for one transceiver, one PC & monitor, and the assorted accessories. At best, when the battery is new, I might get 15 or 20 minu

The York "Affinity 3S" heat pump system has just such a beast in it. Wherever you see reference in their literature to a "variable speed air handler", you know you're dealing with a PWM RFI generator
