<div dir="ltr"><div id="gmail-:43o" class="gmail-a3s gmail-aXjCH">An update on the low temperature
situation that I had a week ago, where the mount <br></div><div class="gmail-a3s gmail-aXjCH">would randomly stall,
or not respond to guide commands, ...etc.<br><br>I suspected that it had to do with the cold weather (around 0C, and probably fell <br></div><div class="gmail-a3s gmail-aXjCH">to -2C that night).<br><br>After
testing indoors with new RJ45 cables, it was time to test the mount in
the cold. <br></div><div class="gmail-a3s gmail-aXjCH">Ambient temperature was around -9C, and the mount housing was
-7C during the test.<br><br>Two iterations were successful: the mount
would alternate between altitude 10 (i.e. it is</div><div class="gmail-a3s gmail-aXjCH">10 degrees above the horizon), and azimuth 170 (i.e. 10 degrees east of south), and <br></div><div class="gmail-a3s gmail-aXjCH">altitude 10, azimuth 190 (10 degrees west of south), with 30
seconds of tracking in <br></div><div class="gmail-a3s gmail-aXjCH">between, and repeat all this for 10 times.<br><br>What
changed? <br></div><div class="gmail-a3s gmail-aXjCH">First, I used a more powerful power supply. It is a 5A 12V
one, that looks like a PC <br></div><div class="gmail-a3s gmail-aXjCH">power supply. <br></div><div class="gmail-a3s gmail-aXjCH">Second, I used flat RJ45 on both
axes.<br><br>Hope the gremlins don't show up on the next clear night, nor Murphy ...
