Veeeery interesting Alberto

Would that give me 192 Kc/s of tunable band width on my SDR radio given the right software?
There has been a lot of debate on the softrock reflector but this one seems to quite good. Do you have first hand experience of it? Christmas is coming ...hee hee.

Pete,

yes, I have one and I am quite satisfied with it. It can sample at 192 kHz, so it will give you from -96 to +96 kHz of band
around the center frequency tuned with the Softrock. Assuming of course that the low pass filters of the Softrock let such
a large portion of the spectrum pass unaffected... usually they cut at a value rather lower than that.... you will probably
have to change some capacitors.

The fact that it does not need an external power supply is handy too...

A suggestion : if you will use Winrad for it, set it to use the ASIO drivers to interface the card. You will then fully benefit
of the 24-bit amplitude resolution.
