    I was wondering if there were any good Open Source SDR radios out there. What I mean by this is that I would like to be able to code my own IF and AF DSP filters, modify the GUI, etc. rather than being locked in to something like the 7300 (which I have).

    With the Flex or Anan can you actually tinker with things under the hood? Or are you stuck with what they give you? Maybe something like GNU Radio?

    Alternately a kit or homebrew project would be cool. I am not at the level where I would want to design it from scratch, though. Anyone have any experience with such a thing? Basically, I like old rigs because I can get in there with a soldering iron and modify things to my liking. I'd like an SDR rig where I can get in there with a text editor (and the source code) and modify/enhance things.

    Thanks.

    Do you really mean coding from scratch, or customization changes? Most software I use/used allow customizations (HDSDR, SDR-Radio, SDR#, etc.).

    Are you looking for Windows or Linux. There are at least 2 or 3 opensource Linux packages available (GQRX, Cubic SDR, etc.)

    Either/or, though I would think customization would be adequate, and likely all I would really have time to do. But I want to customize IF filters, not just AF, which is pretty easy wth a lot of software and a sound card.

    Thanks.

    Take a look at the PlutoSDR from Analog Devices. It's purpose is to be a learning tool, but they accidentally built in some pretty neat features, like 70mhz-6ghz coverage and full duplex rx/tx. Cheap, too.

    SdrConsole already supports the Pluto in Windows, so you can play with it immediately.

    The Open HPSDR project has been running for about 14 years with the purpose of encouraging homebrewing, experimentation and to advance technology that could be shared. Several vendors selling SDR radios based their commercial products on this foundation. TAPR has assisted by sponsoring group purchases of kits and pre-built assemblies. Flex Radio assisted by sharing their open software.

    There has been an active forum, weekly internet conference calls, and trading/sales of components.

    Active? The home page hasn't been updated for 6 1/2 years apparently. At first glance that is not a sign of an active project.

    The Mercury RX module shows as no longer available. If it's not a complete project, why bother?

    Don't get me wrong, I had some hopes for these projects years back, but they just look dead to me now. :(

    Criticize, criticize...

    [EDITED for sunshine]

    The project is there. You can pick and choose the parts you want, and choose what you want to do with it. The info is there, some stuff can still be bought from TAPR, some is offered by commercial vendors, you can always buy used stuff from other hams, finally you can take the OPEN gerbers, schematics and make your own boards!!! *throws up arms*

    The functional blocks have evolved over the years, and some blocks are not used in later system concepts. There are at least five different ways an SDR radio can be put together with various mixes of blocks. I"m no longer up to date, and I''m not certain the Mercury block is used in the later concepts.

    The HPSDR project has been a major achievement of volunteer design and production. It is a great resource for anyone who wants to get their hands dirty with SDR at either the hardware or software level. It isn't spoonfed, turnkey solution. If that is what someone wants then go buy a new commercial SDR.

    Harumph, bill.
