More shack cleaning:
Is equiv of Shure 450D but used with HARRIS RF-3200, maybe others.
Diff from 444D / 450D series is brown/tan color and 'monitor' switch
position along-side PTT button. It can be used for any 'op' need: enable
something like CTCSS etc.
Can change 8 pin conn to work with any dynamic 500-1k need.
