RE: [Discuss-gnuradio] HDTV Receiver and additional hardware

[Berkley, Antwong L.]

Chuck,

Thank you for the offer, I would like the help.  I want to explain what I am 
trying to do.  I am currently enrolled in a Software Defined Radios course at 
Virginia Tech.  For my semester project I want to demonstrate the flexibility 
of SDR.  I want to receive a HDTV or alternate frequency and transmit it on 
802.11 using the USR

In order to do my project I plan to use gnuradio and ossie(Virginia Tech 
middleware). I want to make some the gnuradio modules or functions compatible 
with ossie.

Here are few questions:  I have compiled the latest version of gnuradio but not 
a legacy version.  Are the the old atsc_rx scripts not compatible with the 
latest version of gunradio?

Can I view some of your scripts?

Regards,

Antwong

Antwong - You will need the TVRx daughterboard, and be able to
compile gnuradio-0.9.  To retransmit you might be able to use
an RFX400 daughterboard, but i have not verified that.

I have some scripts that will interface a usrp/tvrx to the old
gnuradio atsc_rx. There are several strategies to use. There's
no up-to-date HOWTO that I know of but I'd be happy to help
on the email list.
