HVR-1600 setup for QAM?

[spotter]

I agree, but its ugly to the point of very unusable. I think for ClearQAM support you should give the user the option of switching it around...

but that's just my 2 cents

To be honest I probably wont change anything. The main reason is that I dont get US/Canada style digital cable here, so its really difficult for me to develop/test any features specifically for it. For now users will just have to get by, relying on the fact its similar enough to DVB/ATSC to work, albeit not as user friendly during setup.

Its not that straight forward. Scanning the existing 139 channels takes 10 minutes or so. Scanning all frequencies might only take a year or two. We'd need to narrow things down a bit. There is probably some less frequently used frequencies, but still somewhat standard, so anyone finds a list of these - let me know and I'll add them.

That said, I think with that last patch most people are finding their channels.

If you scanned at 250 khz increments it would be roughly 900 x 4 times as long so thats only a month or so. And for me a scan is about 20 minutes so two months.

I found out why my card wasn't picking up any of the QAM channels. I guess it's because they're all at a higher frequency than the programs are scanning at. This is an old list but one I found:

Unencrypted:
CBS-HD - 783Mhz
Fox-HD - 783Mhz
NBC-HD - 843Mhz
ABC-HD - 843MHz

Encrypted:
Discovery-HD - 855Mhz
UNI-HD - 351MHz
INHD1 - 693Mhz
INHD2 - 693Mhz
ESPN-HD - 849Mhz

How do I enter those in the qam.ini file?

Open QAM.ini with notepad and just enter them like this, the encrypted ones you won't get just the ones in the clear.

134=783000,0,133
135=843000,0,134

There is also a header at the top that you need to change right under [DVB]

0=135

Do I need to rescan after that?

Last night I found two CTA QAM stations on my STB at channels 130/829.25 and 132/841.25 that no software finds. They show as -2db so they are quite powerful and this does look like a driver issue.

Does it report any signal strength in the -native.log when it tries that frequency?

Yes.

I was going to post something on this, but I didn't people start scanning if there is problem I greped for lock and carrier and I've found this type of issue. I do have two clear QAM channels on 132.

Code:

2007-07-09 23:46:36.573    INFO    Setting CarrierFrequency(841250)
2007-07-09 23:46:39.534    VERBOSE    locked=0    present=0     strength=19000     quality=20
2007-07-09 23:46:39.535    VERBOSE    locked=0    present=0     strength=19000     quality=20

I assume lock is not found, yet there is strength and quality.
