PEAKER ICROPHONE
A Speaker/Mic can increase operating convenience and extend communications range.
Each is equipped with a dual plug connector which mates with the EAR and MIC jacks on
the top panel of the transceiver, disabling the internal speaker and microphone. The speaker/
mic cable allows the transceiver to be left clipped to your belt, or to be held overhead
above obstructions for improved performance. Also, using a speaker/mic for mobile op-
eration allows the transceiver to be left in the MMB-32A Mobile Hanger.
Hold the Speaker/Mic close to your ear during reception; or if preferred, connect an exter-
nal earphone to the plug on the Speaker/Mic, attenuating the audio from its loudspeaker.
To transmit just hold the Speaker/Mic close to your mouth and close the PTT switch on the
microphone.

NTENNA ONSIDERATIONS
While the supplied YHA-16 rubber flex antenna is convenient for short-range portable
operation, the standard BNC connector allows for use of a higher gain antenna to extended
range in base or mobile operation. Any antenna used with the FT-23R
should have an
MK ‡U
impedance close to 50 ohms on the 2m amateur band. If a feedline is used, it should be
good quality 50-ohm coax. Obtaining a proper fit with some BNC plugs may require re-
moving the rubber gasket around the antenna jack on the transceiver.
