[ICOM] Does IC-T7H have 2-wire or 3-wire earphone jack?

[Gary Fiber]

The 3.5 mm speaker jack is 3 wire connector but it appears only the Tip 
(Speaker Audio) and Sleeve (Speaker Common) are used leaving the center 
section, Ring, unused. So a set of ear phones should work fine even 
those with just two circuits, mono connector installed.

Hope this helps
