Has any one built the SDR2GO ? I did and had a lot of enjoyment out of it. The sdr 2go is a dsp board that does all of the I/Q modulation, demodulation and tuning for a softrock eliminating the need for a computer.
I posted a video of it on you tube here .. One CQ and got a hit. https://www.youtube.com/watch?v=vEfyI4sVFNI
I have another one that I am going to start building so I have decided to sell this one on ebay.
Here is the listing number 271420799971
It can also be found by looking for QRP.
There has been another project started that has a small spectrum display.
When I am finished with the SDR2GO, I will be starting this one.http://www.stm32-sdr.com/styled-3/index.html
