No need to remember the "pull" position, just download the SImVim version 9.55c (uploaded today).
Now, the plugin detects if the Com is controlled with single encoder or dual.
If dual, the secondary "pull" function is not active, the Mhz knob is always control Mhz.
For power LED, as I said before, just add the f=i after the parameter name in the data.cfg
Actually, if you want to get the LED be Off when the device is fully unpowered, it will not work this way, because in SimVim program the radion device can be unpowered not only when its power switch is off, but also when avionics off or bus voltage is less than needed for this device. You can wait until we will add the "power-off" parameter for every radio device.
