Recently, I have been having problems with locking on to Channel 6 (ABC from Philly) using the Samsung 151. In the past, it locked on quickly and had a strong signal. Now, it takes 2-3 minutes to lock on but when it does, the signal is strong and there are no other problems. A forum member suggested it might be the PSIP the station is sending out. Are any other members having the same problem with that station?
