Wonderful new SDR design described by Ashhar Farhan
A video of a presentation by Ashhar Farhan, VU2ESE, has been posted and I can't recommend it highly enough. He describes a new design for what looks to be an easy to build SDR based around a Raspberry Pi. Along the way, Ashhar also clearly explains many of the key parts of how a Software Defined Radio works.
The paper that goes with it can be viewed here. Thanks to Stephen, VK2BLQ, for drawing my attention to this and for Bill at Soldersmoke for the link.
Today is a bit sad for me as I'd hoped to be going to MayHam at Wyong but due to a pandemic lockdown in Melbourne I'm unable to leave my home.
This is great news, I expected Farhan was up to something. And he has tackled SDR in his generous, open, no nonsense and entertaining style. Plus he is extending his uBitx design as a baseband analogue front end to an RPi processor. I expect this will generate the same kind of excitement that the uBitx did in 2017. Time to start reading!
Bad luck on MayHam, but we Melbourne based VK3s are in the same boat for now.
