Output power for tuner tuning.

Now that I'm getting accustomed to the operation of this wonderful radio. I've got a question about the tuner output power. During setup in the TX Band settings Ive set the Tune PWR to 15 watts. Now Ive observed each morning when i turn on the radio, no matter the band, I'll select the antenna and touch the tune button. It'll show tuning to settle on freq with the output at 30+ watts. Now after a while, I'll go to another freq. and push tune. It'll tune and settle on the freq with the 15 watts as set in the TX Band settings. Now i don't believe this to be a problem, Just wanting to know if this operation is normal, after the setting of 15 watts??

Thanks,
Jeff/KA0M

    Note that TX Band settings is information only where power is concerned. Power is not set here. Use the GUI and the tune slider. You should set the tune power for each band you use. Those bands where it is currently 30+ watts can be adjusted to 15, or whatever, and then when all done save your settings as part of a transmit profile. This document includes reference to tune power and transmit profiles.

    I get it. I'll clarify, The 30+ watts are viewed on my LP-100 watt meter as it tunes the AT-Auto tuner. When it shows me that the tuner has tuned to 1.09 SWR the power out shows 30+ watts. I did set the tuner power in the TX Band settings to 15 watts for each band i use, or going to use. I'll look into this slider as you describe.

    Thanks

    OK I guess I need to state I'm using the 8400M model. Ive looked in to the slider. I found it under the MIC screen labeled TUNE. And it corresponds to the setting I have in the TX Band settings..

    @Erik Carling EI4KF Each time I turn on the radio, my settings don’t match exactly what they were last time, so I just load the required profile. You can set the tune power to X, and it will always stay on the TX profile. I usually set it to 10W, and it works perfectly for me as long as I load my profile before using the radio.

    The tuning power always goes back to the 15 watts by its self after a bit of time. Its just at the first time using the tune button. its always at 30+ watts. its not a real issue, just wanted to understand why this occurs.
