Improving cooling of JUMA PA100-D
Posted: 28 Dec 2017 13:39
Greetings,
I am using my PA100-D mainly for digi modes. SWR is below 1.5, still PA gets hot (70 degrees celsius) when operating in digi modes like RTTY , Olivia, JT65 etc. Usually running max.50W
Is there an easy modification to improve cooling of the PA ? Replacing heatsink or bigger Fan ?
