The IC-706 and 7000 have mic jacks on the control head, as do about all the 
commercial UHF/VHF radios with remoted control heads. You hear a lot of the 
icom and Alinco HF radios with remote mounted heads in the mobile with RF 
feedback though unless a lot of work is done to them, ferrite beads and what 
not, Running them with no added protection other than what's from the 
factory almost always leads to feedback on HF, I don't know if that's why 
Kenwood just doesn't bother or if they have other reasons.
