Right side runs warmer after KRX3 install

[Brett Howard]

Is it normal for the right side to run quite a bit warmer after
installation of the KRX3.  I did a quick google search and no nabble
hits came up.  I'd assume that the two regulators on the right side are
running warmer because of the greater consumption.  I assume that when
the SUB is off that this will run cooler but haven't tested this yet...

100% normal -- not to worry.

If the entire panel starts to glow, reduce CW speed.

A dull orange seems OK Wayne but smoke from the paddle is hurting my eyes.

One other stupid question... In prep for FD I decided to do some TX
tests...  I found that the radio starts limiting power output and giving
HI CUR messages around 66 to 68C PA TEMP.  I recall Eric stating that
the rig would be fine to 85C.  Is this HI CUR message normal at this
range?  I'm transmitting into a 50 ohm load that is capable of 100 watts
continuous and transmitting at 100 watts.

Thanks

Hello Brett,

Your question:
Is it normal for the right side to run quite a bit warmer after installation
of the KRX3.


I did notice the same effect. I asked support and they confirmed it as
something normal. (I didn't expect that increase in heat production as
well).

There are two transistors mounted to the right side panel. The panel is used
as a heat sink and only gets warm. It is operating normally.
