[Elecraft] Re： XV50 cooling

[Eric]

Don, some other considerations:

1). What about the other components inside the XV?  If the power module is happy running at 100C what does that do for everything else in the XV running at 60-70C with no airflow?

2). My ambient temp in the shack during EME is 80F even with the house A/C running due to the tube PA.

3). Does the XV144 run at the same efficiency (waste heat output) as the XV50?

Thanks for your assistance. I look forward to your measurements.

Johnny,

Prior to testing, I have reviewed the datasheet for the RA30H0608M module that is used in the XV50.  The power module is specified to operate within spec at 110 degrees C ( 230 deg F).  While that is too hot to touch (in excess of boiling water temperatures), it is well within the device specifications.  SNIP
