These dongles are marginally useful but suffer severely from lack of input filters and gain distribution problems.

Yes, of course they are not in the same class as software-defined radios from Flex Radio Systems or National Instruments (the USRP).

But what do ya want for $15? LOL

They serve many purposes, the least of which is introducing people to the world of signal processing on a PC with free software.

Thanks for this info. I had not heard of this. Certainly cheap enough to try.

I just bought the radio shack emergency crank radio for $12.99- works great for Noaa weather.
