Do you use a hand held mic? If yes, does the handheld have a standard
aircraft type mic jack?

Do you use the speaker that is on the hand held, or do you have some type of
head phones?

Handhelds usually come with an adaptor that will accept standard
two-plug aviation headsets. You will also need a PTT switch to plug
in-line with the mic plug if you are using a standard headset. ICOM
A2/20 series handhelds had an optional headset adaptor with a PTT that
could be set to PTT or VOX. The switchbox also had mic gain and sidetone
adjustments.
