        Save money on another Kiwi or tell a friend [KiwiSDR sometimes on drop.com for $100 off MSRP]

        Beagle Bone & KiWi grounding and ESD protectionSorry, I'm neck deep in a new project and just skimming these long posts. Perhaps Seeed put the wrong reel of resistors on the pick-and-place machine resulting in a bunch of BBGs built with a 3.5k going into R136 instead of the 0.1 ohm called out on the schematic (same as on the BBB). This is the only 0.1R 0805 resistor on the schematic as far as I can tell.

        Seeed KiwiSDR metal enclosure finally available!FWIW, Mouser USA is currently showing 4 enclosures in stock. I don't recall seeing this before. Shipping will be faster and less expensive than buying from Seeed for those of you in the USA: http://www.mouser.com/Search/Refine.aspx?Keyword=kiwisdr

        periodic drop-out with ver. 1.240 ? [fixed in v1.241]There was a change made in v1.240 that fixes one problem for the guys making >= 6 kiwiclient connections for use with the external WSPR processing script. But it involved making a "risky" change to the task priority of the internal web server of the Kiwi. I was very worried this might cause problems with the real-time response of the audio tasks. And, despite all my testing, this now seems to be the case.
 So I'll revert that change in today's update and hopefully that will fix it. We'll have to find some other solution for the WSPR guys.

        raw I/Q channelsWhen you mentioned "external decoders" I assumed you were interested in I/Q obtained from the L/R channels of the browser audio output, e.g. so the browser could be used to control the Kiwi. It is indeed possible to connect over the network (via web sockets) to the Kiwi server and issue the same API commands as the browser UI does to set frequency etc.
 An example written in Python that works on Linux/OS X is called kiwiclient/kiwirecorder available here: https://github.com/jks-prv/kiwiclient/tree/jks-v0.1 It is capable of recording to .wav files but there is no reason you couldn't stream to another application. I think Christoph was working on (or has working) an interface to GNUradio this way. The I/Q mode bandwidth is of course limited to the audio channel bandwidth (currently 12 kHz).
