So, unlike analog channels, you cannot fine tune a digital channel. You can,however, adjust your antenna to improve the reception of available digital channels.If the signal strength meter indicates that the signal is weak, physically adjust your antenna to increase the signal strength.Continue to adjust the antenna until you find the best position with the strongest signal.ROONNON^pwq*Otlryz~t~U*Xzp******E*Pyp}*****R*]p}y[tn}p*_p~* * * #^zyo*_p~^trylw*Tyqz}xltzy
