For the last two years I have had no issues with Digital Signal on the TV in the Gungahlin area.
In the last month, I seem to be getting extremely high bit error rates on Win and occasionally Prime to the point that it comes up with Weak Signal. This usually happens at night, and sometimes could be several hours before a decent signal comes back. And no storms or rain and in most cases no clouds when these issues occur.
I have a reasonable background in electronics and antenna design from Amateur Radio days, so I understand, signal loss, benefits of Quad Shielded cable, amplifiers etc, and everything is in check and been checked.
Absolutely nothing has changed in the house or to the cabling for over a year, which is when I found that the antenna wall connections were not even connected (at the splitter) and we had been watching TV for a year using basically the cable running in the wall. What it does provide however is an indication that the signal is quite solid, and improved greatly when we connected to the Antenna proper. Antenna is still in the same direction, nothing moved…still pointing to Black Mountain.
I have also rescanned a few days ago to pick up all the channels again, just in case, but with no change.
I also know that the incorporated signal information built into some of the later digital TV sets should not be relied on, more for comparison than a source of truth but when this problem occurs with WIN, the signal strength is still high, in fact it is the same as when we are receiving a good signal, its just the bit error rate starts rising, initially with some minor bit errors, rising to 2000 bit errors and at that point diving off the “digital cliff” as they call it.
Sorry for all the detail, just thought it easier to provide all information and see if others are seeing similar issues.
