[Elecraft] XV50 cooling

[Don Wilhelm]

Eric,

Have you actually measured the temperature rise?  I am interested in 
just how much is "excessively hot".
While it does get warm, I have always found the temperatures to be well 
within spec for the output module.

I have an XV50 here for repair right now.  It is next in line for work, 
and I intend to get to it this weekend.  After it is repaired, I will 
measure the temperature rise on the bottom panel right under the heat 
spreader.  I have a Fluke 279 with a temperature probe available.

Report on Monday.

73,
Don W3FPR

It runs excessively hot at 10w out in digital mode EME when used one minute on one minute off,  so i dont think  just getting new panels will help you.  I use a small muffin fan blowing air underneath with the xv-144 up on the optional tilt stand and this simple solution works great.
