I constructed the ARM Radio SDR designed by Alberto di Bene (I2PHD) and described in QST magazine (June 2019). Narrative description including links to related resources at lloydm.net/Demo.... 73, WA4EFS
Hello! Good work! Is it enough STM32f411 to process IQ channels (0-5kHz after an IQ quadrature RF mixer ) for AM, SSB, NFM? I want to make an AM FM SSB transciever with digital signal processing.
Hello and thank you. I did not design this project, just put one together. The original design is by I2PHD (referenced in the accompanying write-up). --Unfortunately, I am not sufficiently informed to guess about the adequacy of the processor for your intended project. But, good luck!
Hello there Lloyd`s Certainly a very interesting project, this ARM radio. Can you tell me where to buy the circuit board with the low-pass filter and reconstruction filter? Thanks in advance, regards, Josef
Josef, the filters PCB is not a commercial product. I transcribed Mr. di Bene's circuit diagrams into Eagle (the free version) and created a PCB layout. In response to your query I have posted the Eagle schematic and board files to lloydm.netDemos/ARM_Radio/ARM_Radio-Eagle_files.zip. Good luck. - Lloyd
