same as what I had on
mine at first, I moved the boards around in many different configs and
was able
to get mine to work by having the OZY in the last slot away from the
power
connector on the Atlas then Penelope followed by Mercury if I have a
slot open
between OZY and the other boards I see your captured results and the
relay
chatter. I tried many different configs yesterday for me this has been
the most
stable. One thing I haven’t tried is testing it with the Mercury clock
set
to 122.8mhz I was using the Penelope clocks before the updates because
of the
frequency shifts occurring between receive and transmit when using the
Mercury
clocks. There is an errata out now to remove a capacitor on Mercury to
cure
that problem. Hope this helps<o:p></o:p></span></font></p>

Keith, Phil at all,<br>
<br>
it looks like Mercury suffers from loneliness and needs Penelope
near to it... :-)<br>
<br>
What I did :<br>
<br>
- Moved Ozy farthest from the power connector, and placed Mercury near
to it, no Penelope card.<br>
No luck, exactly the same bad behavior.<br>
<br>
- Moved Mercury one slot to the left and added Penelope between it and
Ozy.<br>
Well, now it works, sort of. Calibration works ok, and the relay
chatter is disappeared, but<br>
there are occasional relay clicks, apparently random. And when the
relay clicks, the tone corresponding<br>
to the signal of the generator has a glitch. And when there are no
glitches, anyway there are occasional pops.<br>
<br>
<br>
To better show the above, I captured a couple of short fragments of
audio.<br>
<br>
This is the tone glitch that happens exactly when the relay randomly
clicks : <a class="moz-txt-link-freetext" href="http://sundry.i2phd.com/glitch.mp3">http://sundry.i2phd.com/glitch.mp3</a><br>
<br>
And these are the pops that I hear, no matter if the sampling rate is
set at 192 or 96 kHz : <a class="moz-txt-link-freetext" href="http://sundry.i2phd.com/pops.mp3">http://sundry.i2phd.com/pops.mp3</a><br>
<br>
Hope that can be of help to diagnose what happens.<br>
