Folks There will be two FUNcube Dongle models, the Pro version and the Base version. The Base model is targetted at the education market as a means to encourage science and technology in the classroom by the use of practical … Continue reading →

Folks Thought you might like to see my programming fixture, a true high tech design! The PCB has the MCU’s programming and debugging pads exposed on the underside, and there’s spring loaded contacts on the test fixture. For just burning firmware, … Continue reading →

There was also a question regarding phase noise at 23cm, there is already post relating to this here: https://www.funcubedongle.com/?page_id=81#comment-110 In fact the first time I ever tried SSB for real at 23cms (as opposed to with a nice clean signal generator) was about a … Continue reading →

Folks I have had a question about the performance of these units. Bear in mind that we are still optimising these units, and there is a lot of tweaking both in software and hardware that we can do. As the primary … Continue reading →

I’ve been receiving a number of questions about the programming interface for the FCD. Although the quadrature I/Q stream is over a standard USB stereo soundcard interface, in order to change the centre frequency there is an additional programming interface that uses … Continue reading →

Today I fixed the problem I was having with the new batch using the new PCB spin hanging. It turned out to be a construction error by yours truly, with a transposed decoupling capacitor and pullup resistor on all three … Continue reading →

Today I built three boards using parts from the production batch with the second, and hopefully final, spin. All worked first time, and sensitivity was as expected with the LNA now integrated, although I have noticed that this batch seem … Continue reading →

The second spin of the PCB has arrived

Last night at 4am I committed what I hope will be the last spin of the PCB before production, should arrive this weekend! I’ve also ordered a full reeled set of parts for at least 100 units.
