General Information

This is a dynamic microphone with a PTT switch (hence the "set" designation) and 2 foot long when retracted coiled cord with 5-pin U-229 mil connector.

Note:  Like the H-250 handset, this mike uses a noise cancelling mike element so it must be used with the mike touching your lips.

There appear to be at least 3 variants:
M-80
M-80A
M-80B
M-80C
Don't know the difference between them.
