There is absolutely no need to add a resistor to the mic. We provide a
K3 menu item to enable or disable bias to the mic connector. That's
how I use it on my K3 here. :-)

Eric - I think you may have missed the point. The suggestion of the 150 ohm resistor in pin 2 was to limit the transients caused when the PTT button is pressed. The problem is worse than the MH2 when using a powered microphone such as the D104. With the D104 it takes several seconds for the audio to build up to the full level.
