SB-401 Mic Data Wtd?

[CHRISTOPHER W. (Chris) BOONE]

Chris,
If memory serves, a low impedance dynamic will work with the Heath
gear.....PTT is short to gnd...on the SB 401, one of the pins is
PTT, the other is mic hi...ground is the shield/ring of the connector.
Cannot recall which pin is which right now..but just use a clip lead
to find out which is PTT (short one or the other to chassis to see
which one keys the rig)
