[Kenwood] microphone wiring Heil Proset for a TS590S

[Steef PA2A]

Hi,

I need to connect my Heil Proset to the TS590S. The Heil AD-1-K cable 
supplies no bias Voltage for the electret element while it works fine 
with an Elecraft K3. Are there schematics anywhere to supply the bias 
Voltage from the TS590S to the microphone?
