Hi guys
I have been trying to get a siano based 1seg ISDB-T USB dongle
to scan and tune under Linux to no avail. Asking around it has
been brought to my attention there might be no app available
that would do this successfully even with an adapter currently
supported by the kernel like the one I'm using. Facing that
scenario and assuming my lack of luck trying to find such an
application supports that claim, I'm wondering if there is
anyone reading this that might be working on writing such an
application and/or in extending an existing one like 'scan'
to be able to work with ISDB-T. Just to avoid duplicating the
effort.
Best regards

If you have all frequencies supported in your country you can the
"scan" command to detected all transmitted channels.

I do have them but scan is showing no results. I'm using a homemade
antenna that is giving 90-100% coverage with the windows app
so I'm rather sure this is not a signal strength nor snr issue.
Here is my freqs file
T 533143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 24
T 533143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 24
T 569143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 30
T 569143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 30
T 587143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 33
T 587143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 33
T 551143000 6MHz 3/4 3/4 AUTO 2k 1/32 NONE # channel 27
T 551143000 6MHz 3/4 AUTO AUTO AUTO AUTO NONE # channel 27
(entries repeated just to try out different combinations)
Now, I know for sure there is a 1seg broadcast at 587143 KHZ
, that's the one I'm getting with the windows app but scan on
Linux keeps showing no results.
I'm attaching the verbose scan output (I have also tried with
-5 with similar results):
