ICOM HM-219 Hand Microphones are the same high-quality microphones as included with IC-7300 transceivers. The great audio reports for these rigs have got to start with a great microphone. HM-219 hand mics fill the bill very nicely.
These sensitive, noise-cancelling electret microphones deliver superior transmit audio to the leading HF transceiver in its price class. Knowing the capability of their IC-7300, ICOM couldn't hang anything but a high-quality microphone on their new rig.
