Hi All
Now might be a good time to add some comments regarding having Voltage and
Temperature permanently displayed on the GUI - see

Hi Dudley,
Thanks for the reply.
Interesting you say the default for the fans is 70c, all the versions of
PSDR I have used have had it set to 40c by default.
If I start the temperature widget immediately upon starting PSDR the
initial temp is normally around 22-26c, if I leave the radio on RX only
the temp rises to around 30c very quickly and then hovers there until I
start TXing, then it gets hot and the fans kick in.
I'll keep an eye on things for future WSPR sessions.
Mike.

Mike,
Pretty well agree with Klaus.. I recently had the engineer comment
that the PAs in the 3K were good to 150 C, but PowerSDR at 100 C will
cut the power back to 25% of the Driver setting (not sure that is still
in effect, have to admit I have not tested this point!) You were
well within the temperature range of the radio and the PAs... I have
not had a problem leaving the fans set to the default of 70 C..
Sorry Klaus, had to jump in..
73,

Hi All,
I have a quick question for you all ....
I ran an over night WSPR session on the 40m band last night with
just 5w of O/P from my F3K.
I was somewhat surprised to see the temperature of the PA being
reported to be at 58 degrees C and at times over 60 degrees C.
Is this normal when running at such low power levels?
The fans were set to come on at 40 degrees C thus they were on a
heck of a lot!
What is the max working temperature of the PA in the F3K?
or put another way, at what temperature do I need to shut things
off to stop them going pop!!
The F3K was running at 13.8v from my Diamond GSV3000 PSU as always.
I had WSPR set to 20% TX and 80% RX.
Mike.
