SDR USB stick
Does it work without a computer? No? Please add the cost of a suitable
computer to the super low price. On 03/12/2014 12:25 PM, Dieter Pelz wrote: I bought a Funcube Dongle Pro3 a few months ago. The Rx performance matches that of my 400$ Icom transceiver.

There's a new version about to go into production which apparently has improved performance including filtering, covering 150kHz to 240MHz and 420MHz to 1.9GHz. Cost is about $199. http://www.funcubedongle.com/ I wonder if the gap in the cellular range will be present in all versions, or just those going to the Land of the Free. mike http://www.canadianaconnection.com/2012/01/canada-party-running-president/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://www.enigmail.net/ iQEcBAEBAgAGBQJQWKmnAAoJEDTMN7GV3zbXtuIH/Aq78CfznKCBfjI7rbVeEPwO P67KaCufFX+cgx4BQcBUxIreCdHV8JSWl0k60T/oLfPsVcpIp0KVIDSfguOCvrhV 260pKMn52V9g/a4TtUJtfdMLeAaPVuqAoqzdXfbIiIJL79Aij+eid7ANH/dWM9B2 lyG7uZPol8Q3VrXI9U62yMSaVczQexfct8ARmeHEIrKF3gC7uV 4wY4ZqI6ZlDowY Y+mHwxELemffrV8eXRWuvD0r5DTuwyHnbId8ip6PvdzVAWpMH5 FOiW9CG4NEvf5f 5bS5oKObmLB2VLTP/8bHNzyEtNKf/wDWwHo39RWvsvwvhA1on/W0OtZBtIzDxG4= =2CM9 -----END PGP SIGNATURE----- |

I can't speak to the Funcube type dongles, but the RTL type dongles with the Elonics (E4000) tuner can be run with a $5 app on an Android tablet. The App provides both signal decoding and a spectrum display. It works on my cheap Chinese tablet with a 1.2gHz single core ARM processor. The downfall is that uses a 256 bit a to d decoder, so the dynamic range is not very high. There also is very little front end filtering. A more generic receiver decoder runs on the Raspberry Pi, and you can use a dongle with the Raphael R820T tuner chips, which start at 26mHz. I have a Drake TR-7 in the works, and assuming it is useable when I get it, I plan to hook up one of the E4000 dongles and my Android tablet to the 46mHz IF, giving me a spectrum display and combining 1970's and 2013 technology. :-) Geoff. -- Geoffrey S.
