<p class="MsoNormal"> A. Use HPSDR-Protocol-1 to the current HPSDR Gnuradio OOT module. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> B. Use new TangerineSDR protocol and Local Host. For module design characterization would substitute a powerful Linux box for the Local Odroid/Raspberry-Pi to allow analysis tools to be used.<o:p></o:p></p>

<p class="MsoNormal">4. Discussion about Juha's gnuradio flowgraph for chirp ionosonde. The top_block appears to be code not auto-generated by gnuradio companion, so it's not possible to automatically go backwards to a graphical flowgraph. Discussion on how
the gnuradio scheduler is asynchronous to the Python code which makes the C++ work function calls not related to specific Python instructions. This can be confusing to folks not familiar with threaded code.<o:p></o:p></p>
