<p dir="ltr">Ooh nice, might have to order one. I've got a bandpass filter for civil airband due to arrive soon for decoding acars with my Funcube, but if this copes with local interference better then it's probably worth the investment. </p>

As far as I know those dongles don't go below 64MHz, or thereabouts,<br>
without modification or an upconverter. The former option being the<br>
cheaper and making use of a hack to bypass the tuner IC. That is<br>
unless someone has started selling a new or ready-modified version...<br>
<br>
They are hugely fun, though! I used one to receive Mode S<br>
transmissions from aircraft overhead [1].<br>
<br>
