I've just purchased 2 untested mkh30 capsules with plans on building the mic from scratch.befor i spend the time and money i would like to make sure the capsules are working. i can test for shorts and check resistance.(does anyone know what the resistance should read?)these capsules are made for an rf circuit. a circuit im unfamiliar with. but my main question is does anyone know how i should test the capsules to make sure they're ok. besides what ive mentioned. are there any special test i should use because these are for use in an rf circuit.any other help,tips or suggestions are appreciated. links that will explain how the rf circuit works? thx
