 				<h1>Test results</h1>
 				<p>I've tested harmonic filtering with a TinySA spectrum analyzer to ensure it meets FCC part 97 spurious emissions requirements (which for VHF must be at least -40dBc for 2nd harmonic and below 10uW).<p>
+				<h2>PCB v1.8x</h2>
+				<p>v1.8a, v1.8b, and v1.8c of the PCB are -53.0dBc for the 2nd harmonic, and 5uW of harmonic power, fully FCC part 97 compliant (tested with 62dB of attenuation):</p>

 				<p>v1.7b of the PCB is -52.9dBc for the 2nd harmonic, and 5uW of harmonic power, fully FCC part 97 compliant (tested with 56dB of attenuation):</p>
