I've recently noticed when flicking through the 6900 function menu , the Tdl mode has a battery voltage read out when I key up it was only reading out 10.1v although the power supply is reading 13.9v when I checked it , has anyone ever noticed this or maybe you could and let me know if it's not only mine that seems off

When I turned the radio power back to 4 watt it reads 12.7v as I turn it up it drops possible not enough amps ??
AM/FM & SSB have different duty cycles, so if that is happening based upon the power setting of the radio, then it has nothing to do with what the radio is drawing from the power supply & is more likely to be caused by a poorly designed/built voltage meter on your radio.
Is that 4 watt reading what the radio is showing you. What the power supply is showing you, or what you know is happening as you have verified it with a multi meter, which backs up one of the others?

Take no notice of the radio voltage readout. I reprogrammed mine recently and thought the default 9 volts for the low battery alert / lockout was too low to start the car. When I increased it to 11, the radio became unusable with the engine turned off. Set it back to 9. I generally keep my engine running whilst hill-topping anyway if it is cold out.
