The R36S - cheap, hackable, and rough around the edges - wasn't built for any of this.</p> <p>That's exactly why it works.</p> <h2 id="the-constraint-advantage">The Constraint Advantage</h2> <p>Modern development hides inefficiency. The R36S exposes it.</p> <p>With limited CPU, RAM, and screen space, you're forced to:</p> <ul> <li>Write tighter code</li> <li>Design simpler interfaces</li> <li>Think in constraints, not abstractions</li> </ul> <p>That same constraint-driven thinking applies perfectly to signal processing tasks like FT8.</p>
