How can I manually add an ota digital channel in order to see if I can get the signal? Specifically if the channel is one with a decimal (like 30.1). I did my manual digital channel scan and it detected and added 5 local ota digital channels. However, I want to see if I can get any signal on some distant ones, but their digital call numbers have a decimal, and the "add digital channel" screen only allows up to 2 digits. Is there any other way to do it if the channel is not picked up on the initial scan? Any input will be appreciated.
