I have had real problems getting the TT-1500 (DVB-T) working.
I have been using dvbtune for some diagnostics.
The following should yield BBC Multiplex on my local transmitter
dvbtune -c 0 -qam 16 -gi 32 -cr 3_4 -bw 8 -tm 2 -f 722000
It does not, I tried adding 166Khz (722166) but no luck. So I tried
just working my way through some frequencies. I can get the
FE_STATUS to report FE_HAS_SIGNAL on some frequencies. I even get
FE_HAS_CARRIER on occasion but never any more than that.
Does this mean the tuner is getting *something*. It's not random for
sure, I always get this result on the few frequencies I have tried.
I am using 184.108.40.206. I know the signal (antenna) to be OK as I get
no issues with a CX based DVB-T module, on any frequency I pick.
This has to be a driver or settings issue. I compile the relevant
modules into the kernel, I get valid firmware loads in dmesg (version
I can insert relevant debugging code if needed - if anyone has any
ideas what might help. I can send a TT unit out if anyone needs one
to test with.
