The answer is.... http://deimert.se/icom_hm36/
As I don't know where the original HM-12 is I replacing it with an HM-36. There are two versions. I will ship the 2 wire with 910. The person who is buying it is going to replace it with a DTMF mic anyway. I will save the 3 wire HM-36 to go with the IC-7200 that I'm also selling. Me, I can't hear any difference between the two mic's. 73 Jeff kb2m -----Original Message----- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Jeff KB2M Sent: Tuesday, November 23, 2010 16:52 PM To: 'AMSAT' Subject: [amsat-bb] Icom 910 hand mic I have two Icom hand mics. Both have 8 pin foster connectors. Both seem to work with the 910, including the up/dwn frequency function. For some reason I labeled one 2 wire, the other 3 wire. I forgot why I did this. Anyone have a clue before I start taking them apart to try and figure out? 73 Jeff kb2m _______________________________________________ Sent via amsat...@amsat.org.
