Yes, you absolutely must make the h/w mod for the diode/resistor change if you enable the tuning mod in the K3 menu. If you do not make the h/e change, and then enable this feature in the menu, there may be intermittent synthesizer communication failures in your radio (which could be temperature dependent etc.)
