The HC4 and HC5 elements in the HM10 are low impedance wheras the Drake microphone inputs are high impedance. Heil does make a microphone for Drake and Collins vintage radios. It has a built in impedance changing transformer. It is known as the GMV.

Has any of the group ever have any compatibility problems with a Heil HM-10 microphone on Drake tube rigs? This particular model Heil seems to be for the solid-state persuasion, from what I hear (??). Thank you. PSG
