<div dir="ltr">Pete,<div><br></div><div>With the disclaimer that this is all based on rumors and such, my understanding is that the RF unit will have all of the RF and control features we have gotten used to: 100W RF output, three antenna ports, transverter ports, feedback input port (from an external coupler), the normal complement of user digital inputs and outputs, and PTT out.
<span style="font-size:small;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">PTT and key/paddle inputs are still an unknown.</span>
As already noted, not present on the RF unit or the Minerva card itself will be any connectors associated with audio, that will all flow through the PC. Now is the time to start researching high quality, low latency (ASIO capable) audio solutions for your PC. For Windows I can highly recommend the Behringer UMC202HD. Not sure about Linux, but I have read that the Behringer is also supported on Linux.</div><div><br></div><div>73,</div><div><br></div><div>Scott<br><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jun 19, 2018 at 5:16 AM, Pete Thompson <span dir="ltr"><<a href="mailto:n3evlpete@gmail.com" target="_blank">n3evlpete@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">***** High Performance Software Defined Radio Discussion List *****<br>

It would also be nice if the PTT, open collectors (e.g. for

<div>The Minerva board will stand on it's own, it replaces
Hermes, Angelia, Orion et al.</div>
<div><br>
</div>
<div>Minerva must be installed inside of a PC of some sort along
with a CUDA capable GPU.</div>
<div><br>
</div>
<div>It's also conceivable that a PC motherboard could be
mounted inside the RF unit, but a PC to host Minerva and CUDA
capable GPU is required no matter what (integrated or
separate).</div>
<div><br>
</div>
<div>There will be a new, dedicated external RF unit to go with
it. Interfaces will be TX RF, RX RF and I2C control. Assuming
the PC remains physically separate, the RF unit will contain
*only* the the equivalent of the PA/RF board found in the
current radio hardware.</div>
<div><br>
</div>
<div>There will be no external microphone or speaker
connections. All of that will/must flow through the PC. Those
who have been using VAC to virtualize their audio will have a
big leg up on the learning curve compared to those who
continue to attached directly to the hardware.</div>
<div><br>
</div>
<div>Not sure about PTT or key/paddle connections. Those might
flow through PC serial ports (as is currently supported by
PowerSDR/Thetis) or they might attach to the RF unit and flow
over I2C to Minerva.</div>
