Hi Richard,
Well that makes sense and adds another element to why you dont want to use the radios speaker and microphone. Which amplifier are you using? My friend Gerry KC0CAT has a small VHF/UHF Amplifier running 50/45 Watts which he uses with his IC-91AD and it seems to work fine for his mobile rig digital. In reality its really not a design flaw with the radio as a single waterproof connection is ideal to the integrity of the radios water tight construction. The flaw lies with ICOMs marketing of accessories. They offer very few alternatives of their own to adapt ancillary equipment to their radio. I purchased the OPC-1797 Connection Cable to use one of my existing ICOM Speaker Microphones to the radio but you have this big mess of interconnection hanging off the radios pigtail. Of course if you want to use the data port for data you have to swap the OPC-1797 with the OPC-1799 Data Communications Cable. Perhaps they need to come out with an OPC-1800 Multipurpose Cable that would extend out 9 of the 12 usable pins. This brings up another question why use a 12 Pin connector when they use 9 Pin connectors on many of their Marine Radios? Not all 12 Pins are connected. Im still looking for the allusive 12-PIN connector itself but eh here is the pin out! Chassis Part Ref No. W1 Order No. 8900016810 Description OPC-1792 (Incl. W2) Chassis Part Ref No. W2 Order No. 8900016791 Description OPC-1763A cid:image003.png@01C8D05B.F5F5B0E0 1 Microphone 2 +5V 3 Clone à CPU 4 RS 232C RX232 5 RS 232C TX232 6 Ground 7 Speaker 8 Ground 9 OPTV à CPU 10 NC 11 NC 12 NC Here in Denver House of Cables is willing to manufacture just about any type of cable we desire we just cant find the plugs manufacture. Another company here in Colorado manufactures a GPS Speaker Microphone for the military and has recently gained approval to market it commercially (however not a submersible variant) that isnt much larger than the ICOM GPS Microphone and provides an LCD screen right on the microphone itself, which when separated from the radio will work as a stand-alone GPS too. Not to mention the fact the microphone can send text messages using DTMF tone bursts to other microphone users, keep track of up to 6 other users on your team, multiple teams etc. Guess this was based on the military version for special forces squads or something. But for those with IC-91AD radios they already have a speaker microphone connector for the radio just doesnt interface with the data port on your radio. http://infinitygearradios.com/pdfs/GPS-MIC-1-Specs-Q2-WEB.pdf http://infinitygearradios.com/pdfs/GPS-MIC-1-Connectors-WEB.pdf Barry A.

Hi Jon, In my particular application I need to have the radio connected to an amp to hit the repeater from my house. It would just make it a lot cleaner not having to pick up the radio with all the wires hanging off it and use an external mic. With the 91 you could simulate the base station experience and have the radio hooked to a computer, amp and 12v supply. Thanks, Richard / N1VXW [Non-text portions of this message have been removed]
