HD 1st bar is the time of taking pic was at highest point but normally it stays together with otherThey vary channel to channel and time to time. On SD weak and on HD same as yours.
plz explain in details with procedure.It is always better to lock you signal using 11510[any middle tp], never you will face problem during rain
I have Mpeg2 Fta receiver.During signal setting, use fta box for perfect signal. Set any middle tp parameter on it.[ex. in case of ts, set 11170 or 11510 tp instead of 10970]. You will get strong signal from all tp . In case if you set first tp as your home tp then last tp give weak signal and during rain,chances are goes blank.
