      <title>New Chip, Who This?</title>

      <description>&lt;p&gt;Porting to a new FPGA is complete (Pluto SDR to Libre SDR). We are now transmitting over the air again in the lab.&lt;/p&gt;
&lt;p&gt;A correlator has been implemented to replace the lower-performance Hamming Distance calculator for sync word detection.&lt;/p&gt;
&lt;p&gt;Next up is soft decision decoding for the 1/2 rate convolutional encoder we are using for forward error correction. This will give us another 2dB of coding gain over the hard decision version, for a total of 7dB.&lt;/p&gt;
&lt;p&gt;It&amp;rsquo;s been a very successful end of the year for Opulent Voice. Thank you to all who support our work. We could not do this and other ambitious work without your help.&lt;/p&gt;

&lt;p&gt;A video of a complete over the air demonstration of the system, including satellite simulator, will be published earlier than planned. Thank you to all the volunteers making ambitious #hamradio things happen.&lt;/p&gt;

      <description>&lt;p&gt;Thank you to all our volunteers that attended #Pacificon this past weekend. Michelle W5NYV gave the MDARC meeting presentation on Friday night, everyone attended a wide variety of events and talks, and ORI made many new contacts and welcomed some new volunteers.&lt;/p&gt;
