Advertisements Today 10/19 several of the local network stations changed their frequencies to accomodate FCC rules. RV-23 is what I am told they will use. As they advised I rescanned one of my two Roamio OTA boxes There is no signal. Nothing, zip, nada. No 23-1 shows up in the channel scans. No signal on the Roamio I did NOT rescan either. What might I be missing if anything?
