HI ALL! Has anyone had experience with KPA500 on RTTY? After two hours of operation transformer was very very hot, drive no more 450 W. I think to change cover and put seperate blower for transformer, or it will be enough? I plan to work from Albania as ZA/YL7A in SCC 30/31.Aug. It is the first expedition with my new KPA500. 73, Yuris
