In a recent post I touched on the work RTL.COM has been doing to improved the cheap entry level SDR dongles.

Having a bit of time on my hands gave me the motivation to track them down on Amazon and finally get an idea of what we can expect over standardize dongles.

There’s a range of circuit improvements in play and this dongle will actually receive below 24mhz (instead of the gain just dropping off), although HF RX is in done direct sampling mode.

There’s some interesting reviews on this product and it just shows how passionate hobby radio can get 🙂
