Hello, My KPA500 developed a PA DISS fault right the start of the VHF contest operating FT8 on 6m. It is: * showing this message on all bands. The antenna is fine. (1.2 SWR) * same fault even when feeding a good dummy load * I smelt acrid smoke :( What do you think I should check or do? Thanks for any tips, Best, Raj N2RD -- -- Rajiv Dewan, N2RD
