Adding OTA Channels to H20 Receiver

[Jackm]

I have an H20 receiver and can receive over the air channels from both Syracuse and Utica. On my TV - I just starting picking up additional channel from Watertown OTA. How can I add those to my H20 Receiver without loosing all the channels I currently have listed OTA. Thanks for the help.

Goes by the primary and secondary zip code you enter. try a zip closer to the new station and hopefully keep your current stations.
