So, if you decide for such a microphone and your device had a dynamic microphone, you will be faced with the question of how to connect it to such a device.
The most suitable are devices that have DC voltage output to one pin of the microphone connector. An example of connection is shown in the diagram. The 2.2uF capacitor is decoupling and the 33k and 68k resistors form the voltage divider. They set the optimal modulation level. A trimmer is not used, because who dares to use one SMD súčiastky, zmestí sa aj do mikrofónneho konektora. Konektory na pripojenie PTT a mikrofónu sú na krátkych vývodoch z neho.
For those who find balanced modulation unpleasant, they can reduce the capacity of the decoupling capacitor several times, thereby achieving suppression of lower frequencies.
Devices that do not have voltage in the microphone connector can be connected directly, only the supply voltage for the electret microphone must be supplied from an external source (flashlight, charging source).
