Aren't you the guy how figured out how to get the ADC data from the CX23881 card into the PC?  I found your website http://www.geocities.com/how_chee/cx23881.htm and looked at the data.  I think I'm going to get one of these cards to play with.  What model number do you have?  I can find PROLINK PV-TV304P+FMRC for $30 at newegg.com.  The Prolink website says it's 8 or 10 bits so I'm wondering if that is the right card.

A year back, there was an idea of getting the TV card vendor to make CX23881 as a cheap ADC device. Any news on this ? With this, a crude and slow spectrum analyzer would probably be possible. Crude here means if there is a high spectrum peak, probably there is a radio transmission but if there a low peak near the noise floor, then you don't know whether it is there or is it from digital switching noise from the hardware itself.


Best regards,

Hi again!

It may not work ? I am doing this as an amateur project. I wish to use WinTV hardware as an RF spectrum analyser ? Bad idea?

I did read an article on the net where a person had claimed he could make almost any TV card with a SAA***** chip into a radio spectrum analyser.

I was hoping to do the same with WinTV inspired by him.

I am currently trying to install GNURadio.

Question : FFTW install does not have a seperate installation guide for Cygwin. It does have installation notes on MinGW. I guess those would do ?

Thank you,
