Have a problem where from time to time, I cannot view a whole bunch of HD channels (eg 497-499, 537)
Had a Rogers tech visit and he determined every one of these channels in question are on frequency 717. He hadnt seen that before.
For now its ok, but sometimes a day or 2 goes by before I can view these channels (get a black screen with message service is not available).
Has anyone experienced this?
The tech put his meter on the cable going to the box as well as checked the signal to the house. He said if anything, my signal is too strong but that shouldnt affect losing channels.
He suggestion was to swap the box if it happens again. Its just weird that is happens for a day or so and then is fine for a few weeks after.
Too STRONG of a signal, could have adverse effects as well.. so its possible its that... too much feedback in the one channel range (especially could happen if that frequency range is towards the inside/outside of the freqency ranges).
At my first basement apartment, the owners had a power booser in, to get good signal to their upstairs TVs.. no boxes.
But we were having problems with our digital box.
guy came in, and removed the power booster from our lead, and left it for the others.. and it started working fine.
I had a NextBox 3 for a few months and created a spreadsheet of signal strength readings for certain channels, including the frequency (Mhz) being used (see below). The left column is the channel and the next one is the frequency in Mhz. The data was collected over a period of several days. As you can see, the frequency for each channel moves around a lot and there is one frequency assignment of 717 for channel 552 (HBO 2).
