Others had already measured the noise figure independently. I quote SINAD because that was all I had at the time of the original FCD to measure accurately in production. You will find that noise figures are already quoted on the specifications page right here and the method used under the observations notes here. Please consider expanding your market base to support the needs of the rest of the community. Pitty such information isn’t published on So far the Funcube has the FM repeater rubber duck ham market cornered, as none of the issues discussed matter to them. Just tune to to a carrier above 1 GHz and hold the dongle in your hand to observe massive drift. The Funcube Pro suffers from extreme drift but you don’t need to run such a test. We also need to see frequency stability versus temperature over time numbers. Once real SDR users measure and post the specification that matter, the rest of the SDR community will know if the Pro+ is worth the asking price. That’s all most hams are and where the profit is, but it’s a shame to limit the potential of the Funcube like the original Pro version badly did. It seems the specifications posted so far are meant to target the FM repeater rubber duck ham community, which is fine. It would be nice to see some real specifications.

What’s the purpose of a 16bit ADC on the digital back end if poor engineering only gives 50dB dynamic range on the RF front end? It’s surprising a demo Pro Plus dongle hasn’t been sent to people who publish real useful Funcube specifications like so the non FM repeater ham toy SDR use community will know the real usefulness and performance of the Funcube Pro+. Poor engineering caused the Funcube Dongle Pro to have worse dynamic range and sensitivity than the 10 GBP RTL E4000 DVB-T dongles available on ebay.

Why isn’t the noise figure measurement methodology published? Why aren’t any dynamic range numbers published? This specification is MUCH more important than nearly pointless SINAD numbers posted.
