K3 PA & FP Temp Settings

[Ron Midwin]

I recently noticed the temperature of the case on my K-3 seemed a little
warmer than usual (the room temp here has been up to 25 C).

 

I checked the 2 settings on the PA TEMP and FP TEMP and they both were
reading as high as 35 C.  I checked in the manual and per instructions,
turned the radio off for 15 minutes, and then back on, and then set the 2
settings to 25 C.

 

The radio still seems to get warmer, and even when I leave it on in standby
the temps both go back up to the low 30's.

 

Is this normal?  Is there a way to set the thermostat (if that's the correct
term) so that the fans go on to keep the radio running cooler?

 

73,

Ron,
35C is only about 97F, totally normal inside electronic equipment when it's turned on.  Nothing to worry about.  My FP and PA temp also stay around 35C in a 23C (74F) room when not transmitting.

And things should run even warmer if you have the sub receiver
installed.
