Ah. Yeah, depending on the firmware, only one of those options is available.

There is a code at the Siano driver that tries to detect it, but it seems that
the logic there is not 100% (well, it works with the devices I have, but I
don't have much Siano samples).

Maybe we could add a different strategy:
- test first if MSG_SMS_GET_STATISTICS_EX_RES work. If it doesn't, fall
  back to MSG_SMS_GET_STATISTICS_REQ.

That is likely better than the current logic, that tries to guess what's
available based on a firmware version.

I'm out this week for a meeting in San Jose. Could you please try to write
such patch and submit to the ML? I'll test it after returning back to Brazil.

Well, you generally need an external antenna to get ISDB-T broadcast signals
on most places, and a good RC6 cabling with low noise TAPs, if you're
using a common building antenna. 

A very high gain internal antenna, placed at the window sometimes work.
