[IRCA] dx dead spots

Hi all….. a topic that has always confounded me is the subject of “dx deadspots”. Literally geographic areas where nothing of a dx nature seems to penetrate. I’ve alluded to this in previous threads and blamed it on Antennas, sunspots, noise…… you know the usual suspects. I’ve even po
