<div dir="ltr">There are a many great ham projects using SBCs. So far I've tried the Raspi family, Tinketboard, Feather and Teensy. The Tinkerboad is about twice as fast as the Raspi 3B+ and sometimes it makes a difference.<div><br></div><div>I just finished building <a href="https://sdr.hu/openwebrx">https://sdr.hu/openwebrx</a> which allows you to share your radio on the internet. It works with a lowly RTL-SDR so it's a cheap project. There are also a bunch of x.25 and APRS projects for SBCs also.</div><div><br></div><div>The Teensy is really interesting. It has an audio library that takes advantage of DSP instructions and is really efficient. Here's the design tool that goes with it <a href="https://www.pjrc.com/teensy/gui/">https://www.pjrc.com/teensy/gui/</a> Filters are limited to 200 taps.</div><div><br></div><div>73 - Martin</div></div><br><div class="gmail_quote"><div dir="ltr">On Thu, Dec 13, 2018 at 1:07 PM Alex Fraser <<a href="mailto:beatnic@comcast.net">beatnic@comcast.net</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
