Re: Narrow filter for CW #ubitxcw


The sofa beams Audio DPS boards...there are several models...are stand alone boards, no coach needed. Simply insert in your audio chain and add power. It works great. Far better than I had hoped. They are worth the investment.

That looks like a cool implementation. Is your audio bandpass filter stand alone or is it an add-on to the Sotabeams filter board?

It sounds like it is a stand alone DSP filter and display.

Is the code on GitHub or somewhere?
