I purchased a 103 speaker mic cable from Argent to connect to my Icom IC-92AD HT. I already have an Icom adapter cable that converts the mini DIN socket on the HT to a traditional dual-pin speaker/mic socket. I am using an Icom HM-75A lapel mic plugged into the adapter cable.
Can anyone tell me how to wire the speaker/mic cable to the DB-9 to connect to the Icom?
