Digital reception in Singleton Western Australia 6175 becomes very poor from 1730hrs to 0540hrs. This happened every night since the 3/3/21. Reception dropping out and very poor quality. Reception on all other channels is fine between those times. Have tried re-tuning tv channels and nothing has made a difference. Therefore I have not been able to watch channel 7 channels at all during those times and for the last 3 days.
