Sorting out the signal levels
I have had a 630 PVR since November, and I am mostly happy with the way it works. I noticed that all my recordings of channel 256 (Global HD) had problems with the sound and video dropping out. I did some checking and found some curious results.
First off, the signal level on the "Tune in Satellite" page (Options 4 - 3 - 1), always shows the signal level on Tuner #1, even if you are watching Tuner #2, so you have to make sure on the System Status page (Options 4 - 7) which channel is on Tuner #1. Also, I noticed that on the tune-in page, it always shows satellite 'A4' regardless of which satellite is tuned. Also, the signal level on the Status page is the same as the number on the tune-in page; so my conclusion was to ignore the tune-in page once the dish is aimed; and just use the info on the status page.
So, here is what I found:
Chan 292; HD; Signal 81; Ecb/no 5.0
Chan 306;SD; Signal 57; Ecb/no 6.3
Chan 375; SD; Signal 64; Ecb/no 7.2
Chan 400; SD; Signal 58; Ecb/no 6.8
Chan 256; HD; Signal 65; Ecb/no 2.6
So probably that last Ecb/no is too low. I understand we have 2 satellites, and 2 polarizations, and HD vs SD; but I don't understand what combination yields the low signal, nor what to do about it.
Any suggestions are welcome.
