Summer in MN is glorious but brief. Nights are short and the sun never gets all that far below the horizon. Compared to long winter nights, this isn't favorable for receiving 4MHz beacons like Windy and DW. Propagation predictions show this and my own experience is consistent with them. The last two nights have had very quiet conditions in terms of geomagnetic conditions, lightning, and local noise. But the beacons are weak here in the 0900-1100Z predawn hours, rising above the low noise floor only briefly. I get clear IDs from Windy, but not full frames of telemetry. DW is mostly just a ghost of an image on the waterfall. Oh well, it is a great time of year to enjoy the outdoors instead!
