Hi all,
I am a novice in gnuradio and after searching in a lot of forums I put my USRP
working and my Gnuradio running. Some FM and AM reception with and without
GUI are working fine. Now I have some problems in FSK. I try to receive in
ISM 433 MHZ some data packets with a data rate of 38.4

<[EMAIL PROTECTED]>Might I recommend buying a USRP instead, with a TVRX board?Because currently there's NO working HDTV codes for USRP. So I think it's not a good starting point for me to learn HDTV. That's why I want a mc4020 instead.Once I've mastered all the tricks decoding ATSC RF stream, I'll

Hi Mao,
Not sure if you saw this, but it's relevant to your questions about HDTV.
Perhaps you and Rafael can work together to get the ATSC code ported
to the 2.x code base and the USRP. I'm willing to help out with
questions, suggestions, comments etc on the effort.
FYI, how we brought the

Here's why I don't want to use USRP to handle ATSC:
If the captured ATSC stream is 16Ms real data and the
IF is 4MHz, then the freq range of the ATSC signal
will be 1MHz to 7MHz, and the pilot freq Fp will be
1.31MHz.
If I use the
Sounds good!
I am still not convinced that USRP can handle ATSC
demodulation. Please tell me how are you gonna recover
the carrier with 16Ms data and 4MHz IF? If this
problem can be solved, the rest are pretty easy.
The reason why I want to buy a working mc4020/mt4937
combo is that I want to
Yes, I believe you are killing the pa threads with this small latency
request. I should have remembered this for Windows. In the current sink
code, the buffer and latency request are based on 21.3 ms. For
Windows MME, this should be at least 100ms on your first try.
Be careful and

The usrp gives you 8Mhz bandwidth which should be enough for
10 matches
