I just bought my Dad a Samsung SIR-T451 for Christmas. [It] does not allow him to add channels to memory manually. He has to use the channel scan to add stations.
add channels manually on the SIR-T451. I've done it lots of times. The trick is that you have to enter the physical
channel number, not the logical
) channel number, when you're trying to tune the station for the first time. If the receiver successfully locks onto the station, it picks up the logical channel number and you can use that number thereafter.
Example: Near me is a station that is known as "channel 25" because it has broadcast its analog signals for years on that channel. However, it broadcasts its digital signals on channel 8. It's in a different city from from most of my other stations, in a completely different direction. So when I want to rebuild my channel list from scratch, I first do an automated channel scan with the antenna pointed to the other city, which picks up those other stations. Then I swing the antenna around and key in channel 8. The receiver picks up the signal and extracts the logical channel number from it, and the on-screen display changes from "DTV 8-0" to "DTV 25-1 WOLO-DT". From that point on, I can tune that station by entering "25".
