D-104 Mike Info

[Multi-Volti Devices]

Yow! I hope someone confirms my gut reaction that that is the kind of power
you use a relay with big coin silver contacts to switch. maybe I'm wrong,
but I think the mike switch would weld. I think most keying circuits are
very low current. I would use an external relay or MOSFET switch,
personally.
