Hello from Portugal! I have a FT-450 (initial verison, not AT or D) and i have a newbie question: as my radio doesn't have internal ATU, i got one from eBay (mAT-30) which is supposed to handle up to "120 watts SSB and CW, 30 watts max continuous duty keydown digital modes on HF". It was working perfectly fine for couple weeks, but yesterday when i pressed the "TUNE" button on FT-450 the magic smoke popped out of the ATU box. Checking inside it i have noticed that all the 100R and 110R resistors which handle the input RF power from radio before delivering it to the tuning circuit have been "fried". In contact with the supplier they stated that this is quite strange because the output power from the radio when we use the "TUNE" button is supposed to be no more than 10W, however i put the radio RF OUT to my Daiwa Wattmeter and measured nominal 100W out when i press the TUNE button. Supplier said this is quite strange and i may have some issue with my radio, what trully speaking i don't believe. As i don't have another radio to check this information, i wondr if some of you guys with experience on this subject could tell me more about it or maybe even someone with a FT-450 could confirm to me if the output power is really the nominal 100W power when pressing the TUNE button. For your record, i was using USB mode on 20m band. Thanks! 73 de CS7BAC, Pedro Silva.
