I only know of the Per Vices product but have not gotten my hands on
it. But I’m really happy that they have produced their own GNU Radio
interface for it already.

My biggest question is if it’s well-shielded enough for the noisy RF
environment inside a computer chassis.

HA HA HA - this article came out the following day. It has a photo of
both the Per Vices card and the person who wrote the above comment !

Well, two separate photos, if one wanted to be technical :wink:

Nice pic Tom! FTA:

It could only capture a narrow slice of spectrum: 100 kHz at most. That was
enough for Law and Order reruns…

How does that work :slight_smile:

I wouldn’t cosider this option,

A few points:

  • I have a PCI DVB card, works great for recording TV. The RF section
    is shielded inside a can.
  • Winradio internal cards has been around for many years, although I
    see they do USB units now as well
  • These guys surely wouldn’t have got to the point of putting these
    things on sale if they were unusable due to RFI from inside the PC?
    Although I note they say on the product page “This hardware is sold
    on an as-is basis without warranty”, which doesn’t exactly inspire
    confidence in the product.
