PGXL Temperature Rise
I lately noticed that when I turn on my PGXL and put it into OPERATE mode the PA heatsink temperature rises to between 50-52˚ when just idling. I have not transmitted since turning it on. The current draw is about 4A. When I put it in STANDBY the temperature drops to about 45˚ after a few minutes. The harmonic load temperature stays at about 29˚ or so and rises slightly when transmitting. If I place the amp back into OPERATE mode, the temperature steadily rises again to over 50˚ while idling without transmitting. This does not appear to be normal behavior. I think I recall lower idling temperatures in the past.
Can anyone comment about this?

What speed are the fans in?
Whay version firmware?

You'll find the temperature rises based on the BIAS current.
I ran RTTY all weekend at 700 watts and never got over 50C, but I am on the latest version.
We have done a lot of work on the firmware/fans and Bias, so the version is critical.

Thanks Dave, 3.8.8 seems to have improved the cooling with the fan cycles. Now the next feature I wish for…is Auto-Standby, after x hours of inactivity. With x being a setable value like 2,4,6 hours.
73, Bill
