Thanks for clarifying that. Yes I do understand the complexity of the demod / signal processing chain. Whats the size & resoltuion of the LCD (SPI i/f) used? Any plans to add a touch interface? Currently the SW has options for using Si5351 with a 25 /27MHz xtal. Are their any other options...

Thanks for the prompt reply. Can you provide a screenshot of the Audio sketch used for the Convolution SDR? That shall help visualize the signal processing blocks, their wire-up and the signal flow. This is similar to and as posted in the Teensy SDR document (in pdf) that shows the "two"...

A couple of more questions: 1) Whats the power draw on the main power rail (QSD + Teensy boards combined) 2) Is it possible to add a waterfall display on the LCD? Are there any spare resources in the CPU? 3) Is it possible to use the ADCs on the Teensy CPU for sampling the I&Q (instead of the...

-------- Thanks there. This is a helpful writeup. The signal processing approach seems different from the Phasing / Weaver methods. What audio setup / amplifier do you have after the Teensy audio board? The AM audio is very good. Can you post some SSB audio samples if you can, in your free...

Hi DD4WH Could you pls post the SW block diagram of the Convolution SDR showing the signal flow and processing done in this Teensy based project? Also perhaps alongwith a writeup explaining the functioning of those blocks? TIA.
