If you want to make a Pi just transmit, you can do that with little more than a wire, although the quality might not be perfect. Of course, you can always use a Pi with a more conventional dongle, and that works well enough. If you are looking to buy one, you might not find the name “raspberrysdr” but suggests searching for “New 16bit 62M real-time bandwidth network shared SDR receiver” which does turn up some results.

The blog post also covers some open source issues where Kiwi is now saying some parts of their code will only be binary in the future and there has been some difficulty finding all of the Raspberry’s files. In the end, the Raspberry looks like a cheap clone of the Kiwi with some benefits, but also some drawbacks. Without proper design, throwing more bits at a problem isn’t always helpful and this appears to be a good example of that. The biggest issue, though, was that the 16-bit A/D didn’t seem to have better performance. The tests revealed a few problems with signal strength measurement and some other problems with the RaspberrySDR. There are also tests of image rejection and front-end overloading.

Probably a software fix could take care of that, of course. The Raspberry - using adapted software - looks as though it does the same trick, but does it around the Kiwi’s cutoff frequency, which is lower. The Kiwi appears to boost signals near its cutoff frequency to compensate for losses in the system. measures a few key parameters on both devices and arrived at some surprising conclusions. This combines to give the Raspberry a wider receive range (up to 60 MHz) and - in theory - better performance in terms of dynamic range and distortion. Other than the obvious difference of the computer and all that it entails, the RaspberrySDR has a higher speed A/D (125 MHz vs 66 MHz) and 16-bits of resolution instead of the Kiwi’s 14 bits. What’s different? tells us in a recent blog post. This is a very similar unit to the KiwiSDR but it uses a Raspberry Pi, along with a handful of other differences. Success of course breeds imitators, and especially when you have an open source design like the Kiwi, you are going to find similar devices with possibly different end goals. The platform uses a dedicated A/D converter, an FPGA, and BeagleBone computer. This popular unit runs Linux and can receive up to 30 MHz. One common hobby-grade SDR is the KiwiSDR. Once you move away from the usual software defined radio (SDR) dongles, you have only a few choices unless you want to drop some serious cash.
