I have a hr44/am21 -- was on a few years back getting setup info. Had a dickens of a time with the WUNC PBS channels hanging the am21 scan. Seems that has been resolved, as a recent scan (to get cozi tv on 5.2) worked just fine. However I see from seaching around that 22.4 in raleigh is broadcasting Antenna TV, but my scan did not pick up the 22.x sub-channels. I did not use a secondary zip, just Raleigh. Should I try a secondary zip? And what should it be to get the 22.x sub-channels? They are on RF27, i.e. WLFL RALEIGH, NC 22-1 27.3 WLFL-HD CW "CW 22" 22-2 27.4 Stadium Stadium 22-3 27.5 TBD TBD 22-4 27.6 Antenna Antenna TV Many thanks, Scott.
