    Flex DOES support fully automatic operation as you describe it. For my Flex 6400 and MFJ-998 combo, I hit the tune button on the Flex SSDR program. It sends a lot power signal to the 998, which automatically tunes. Then I release the tune button and the radio automatically reverts to higher power output. W8ASA

    Are the characters in focus?

      The quality of the video from the Restream system is not the same as the original video submitted, now that I am comparing. There seems to be some quality loss when we record a Restream broadcast. Thanks for bringing it to my attention.

    I believe the Yaesu ftdx 10 works automatically. It tunes at a lower power then goes back to full power once done tuning.

    The general question should be how much heat is produced in such tuners with 1KW and an antenna SWR of 3:1 and worse. And how long does it take to smoke. Why don't you do the key-down test and show what's really going on. Greetings from DL DH1KJ Joe

    ..I wonder a bit why no one mentions a deposed mast tuner. With all these tuners installed in the shack, you still have the disadvantage, especially with multi-band antennas, when matching on different bands alone that you have to match the feed cable with - partly quantity losses and the risk of jacket waves.
    I work with a Stockcorner JC4s - this is installed directly at the bottom of the mast. From its terminals I go directly into a 9 meter long two-wire line - and then directly into the two legs of the 2 x 18 meter long inverted vee. This works great - I don't have to match any feeder cable - and the antenna goes from 10 - 80 meters with very good success. 160 meters is also possible - of course not with such great efficiency - but it works...
    Shack tuners - yes - of course this is also possible - but I have made the experience that antenna tuners, if they are installed directly in the feed point of the antenna - work much better than from the shack itself.

      I agree 100%. I have an LG remote tuner at the bottom of the mast in an outdoor box and 450 ohm ladder line to the top of my inverted V. Works great on all bands. Thanks for your comment.

    I wonder WHY you are limiting your view to "under $1000" tuners.... if you are in High Power, then suitable high power trans match are needed to provide headroom. The components for high power are costly. So you should add in the Palstar HF-Auto with remote head accessory, and the Flex Tuner Genius. Art W1SWL
