Ответ:If you are using an Icom handheld radio you will need the Icom headset adapter that is specific for your Icom. Once you have that, the intercom in this package will connect to the radio. As for the PTT, you can use the one it the package but I recommend the Icom PTT on the below link: http://www.aircraftspruce.com/catalog/avpages/icomptt.php?clickkey=23714
