2021年6月的QST杂志第44页:Automatic Antenna TunerThe FTDX10’s internal automatic antenna tuner isdesigned to handle impedance mismatches that resultin SWRs of 3:1 or less at the antenna port. The tuneractivates with a push of the TUNE button, and therelays chatter madly for a couple of seconds as itattempts to find a match. Assuming an acceptablematch is found, the tuner then appears to track acrossa substantial range within the band, adjusting quicklyas necessary each time you transmit on a new frequency.I can’t help but mention that the FTDX10’s autotunerwas more generous in its matching ability compared tothe tuner in my own transceiver. In one instance, theFTDX10’s tuner found a match with my antennasystem at a frequency and impedance that my currentradio’s tuner stubbornly refuses to accept.
在2019年QST杂志第54页上,原文:Antenna TunerThe internal antenna tuner quicklytunes an antenna system with up to aspecified 3:1 SWR to near 1:1, and itremembers the tuner settings for thatfrequency. I found that it could tunesome antennas with a higher SWR,but the internal SWR meter onlyshows up to a 3:1 value, so it can behard to tell. Attempting to use anantenna with more than the specifiedmismatch can be a risky business.While the radio cuts back to 10 W out(adjustable) during tuning, it will try topush whatever power setting youselect during operation, and damageto tuner components is possible inany tuner if ratings are exceeded.

BD6AHP:貌似Y记的机子在ATU调谐是都是直接按照正常通联设定的功率发射的,不会自己降功率,至少我用过的FT1000、950、2000都是这样。 (2022-06-06 08:16)
