<h2 id="freedv-2020b"><span class="header-section-number">8.4</span> FreeDV 2020B</h2>
<p>Experimental mode developed in February 2022. The goal of this mode is to improve the performance of FreeDV 2020 over HF channels.</p>
<p>Here are the three main innovations, and the theoretical improvements:</p>
<ol type="1">
<li>Compression (clipping) of the 2020x modem waveforms has been added, which is worth about 4dB. This should also improve the original FreeDV 2020 mode. The Clipping checkbox is located on Tools-Options-Modem. As per the other warnings in this manual please make sure you transmitter can handle the higher RMS power.</li>
<li>2020B is like 700E to 700D - it works with fast fading but requires a few more dB of SNR. This will make it usable in European Winter (or over the South Pole Argentina to Australia) type channels - if you have enough SNR. The challenge with this mode is squeezing all the information we need (enough pilots symbols for fast fading, LPCNet, FEC bits) into a 2100 Hz channel - we are pushing up again the edges of many SSB filters. It also uses unequal FEC, just the most important 11 bits are protected.</li>
</ol>
<p>This modes is under development and may change at any time. If you experience comparability issues with another operator - check your Git Hash values on the Help-about menu to ensure you are running the same versions of LPCNet and codec2.</p>
<p>It is recommended that multi-rx be disabled when using 2020B. This mode is not supported by multi-rx, you will need to manually coordinate the mode with other stations.</p>
