Modulard Adapter for 8 Pin Yaesu Transceivers
INRAD Microphone Adapter Cables adapt the INRAD microphone cable (which is XLR to 1/8 in. mono) to match the connector on your radio.
The mic cable is plugged into the 1/8 in. female mono jack on the adapter cable. The mic connector on the adapter cable then plugs into the microphone jack on your transceiver.
The 1/4 in. female jack on the adapter cable is for connecting a Push-To-Talk (PTT) footswitch or hand switch. Even without a PTT footswitch or hand switch, your radio can still be used in VOX mode.
