Not quite correct.
Modern radios with electret elements use a voltage sent up the microphone wire from the radio to power the microphone element as they work by varying capacitance. If you stick a normal mic dynamic or aftermarket power mic straight on you can damage both the mic and radio as the mic will get voltage from the radio.
On some new radios you can wire alternative mics by disconnecting the power wire inside the mic plug, but on others you may not be able to do this.
I know that on the majority of President radios and Anyclone types they will work with an alternative mic if the volateg pin is disconnected, but the Presidents in particular never seem to sound all that great.
