Hello Gentleman,
The structure and architectural of XV50 and XV144 are the same. The proposed
test from Don would be useful. Eventually, we do need an official confirmation
from Elecraft some time in due course. Let us stay tune and wait for Don's
test.
cheers,

Yes, Eric, a retro kit is good idea and all new kits should run with such a
modification.

主題： [Elecraft] XV50 cooling
I have a late-model
Hello Don,
The situation is - after I operate either XV144 or XV50 for a 10-15 minutes QSO
under 10w FM or 20 w SSB (the advertised rated output from Elecraft, p.3 of the
owner's manual), the bottom plate (or even one of side panels) is too hot to be
touched.
I would be very interested in
Johnny,
Be confident that I will test at the 10 watt level (simulated FM) for a
significant length of time, and also Eric's situation - 10 watts, 1
minute on, 1 minute off. I did similar stress testing on both large and
small devices for the last 10 years of my professional career - I am
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
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
Hello Jerry,
I am afraid that my observation with my XV50 and XV144 is different.
These transverters are extremely hot if they are run at Elecraft's advertised
rated output of 10W FM and 20W SSB. The heat is from the power module and NOT
the attenuator resistors.
For both XV50 and XV144,
