Acorn II SDR Kit

This year at the RSGB convention we will be running a buildathon based upon the same format of the other successful build events in the past – this is an excellent time to attract a new audience to our events.

This year however we are using a new kit. The Acorn II kit developed by Kanga Products and M0XPD, is a Software Defined Radio kit that runs on the SSB portion of 40m. But the kit can also be configured to run on any HF band – assuming you have a Band pass filter & a suitable Local Oscillator. The kit has been developed to allow you to pipe in an external Local Oscillator and allow you to connect Band pass filters for other HF bands.

The kit was developed to run with the M0XPD Si5351A Arduino shield, which allows you to use the Arduino as a VFO. And can plug straight into the radio as a local oscillator

Using just a stereo line in on a sound card, and some widely available SDR software (Such as HDSDR), you can get great results from little financial outlay. It is indeed a great introduction into SDR.

I built one of the prototypes here is a video of the build. I will cover configuration & set up in a forthcoming video – perhaps when I have access to a good 40m antenna
