Tweaking BritX based Hambuilder exciter internal speaker and headphone jack

First version of HBR4HF or HBR10HF are used hybrid microphone with loudspeaker. Basic idea using this is to reduce complexity and cost. also considering it as portable radio. How ever there’s a requirement to operate with external audio amplifier or external speaker for better audio receiving. The newest HBR4HF already have internal loudspeaker, and the newest HBR10HF already have audio jack also.
