I've been having issues with both KAGS and KRHD over the last week. Neither are even showing up in a tuner scan right now. Not unusual for KRHD, but pretty odd for KAGS.
Weirdly, during the same timeframe, I've been consistently getting most of the Waco/Temple/Kileen stations (including, fortunately their NBC and ABC affiliates), and even a couple of DFW ones. It's keeping my channel lineup a mess. Solar flares are probably the culprit.
