Tune power indication with SmarSDR v1.4.11

I am running SmartSDR v 1.4.11 on Windows 7 with a 6700.  In the radio setup page I have the Tune Power set to 10 Watts.  However when I select Tune the 6700 does indeed deliver 10 Watts, but the Power Slider continues to indicate 100% while in the Tune state.

I believe someone else mentioned this.

    Your observation with the tune control is correct.  The tune pwr bar indicates the tune power, the above RF power is the power of the radio in a mode other than tune.  I think it has always been this way if my memory is correct.  Jim K4JAF

    One of the reasons I find the TUNE power and and RF Power useful is that when I want to tune my SB-200 tube amplifier for a band - I want to start out tuning at a low power level of 5 watts to get the load and tune controls on my amp close before I run it at full 30 watts (all I need to drive my amp to 600w PEP).

    Meanwhile, I can just leave my RF Power control on SmartSDR at 30 because when I go to SSB mode (or other modes) it will use THAT 30w  power level and get me my 600w  PEP.

    And then I set my TUNE power back a bit if I need to retouch the tuning quickly without overheating my 572b tubes too much - saves the tubes and elongates their life.

    The Tune and RF power is the same as it was in PowerSDR and is useful. Just like Jim said - the RF power control is for when you go into a mode OTHER than tune.
