Hi all...I have a FT-450d its only a few months old...I notice if I am transmitting for longer than a short QSO the right-hand side of the radio gets quite warm...42 deg c in a 20 deg c room. I have been having a few longer than usual for me rag chews on 80m SSB voice of late...each over lasting 2 mins or more. The Whole QSO may last 20mins+ I use a 43mt long doublet antenna with a perfect 1-1 match. The heat in mainly down the whole right side and nowhere eles...I find it very worrying. Looking under the top cover the finals are inboard from the side panel... Can anybody give me any advice who may have a similar radio. Make me nervous using the radio.
