HD Radio from 95.5 WPGC back on-air after hiatus

For at least three months, HD Radio from one of my local stations, 95.5 WPGC Morningside, MD, has been off-air for unknown reasons.  This was great for me as a DXer, since it freed up 95.3 and 95.7 FM for DXing.  Since WPGC’s IBOC has been off, I logged 4 new signals on 95.7 FM, more than half of them via Sporadic E.  During a routine dial scan yesterday, I found that WPGC has resumed its HD broadcasts, rendering its adjacent frequencies unusable for regular DXing.
