Please look into the feasibility of creating a 2 way radio cable for your SR10 specifically designed for the Yaesu FTM-10 series of ham radio. This includes the FTM-10R and the FTM-10SR ham radios. The VX-8 hand held also uses this same connection plug. The Yaesu FTM-10 ham radio was specifically aimed at motorcycle riders with its waterproof face plate and on the FTM-10SR version also has a waterproof / dust proof base. Its a pretty popular radio among the motorcycle ham radio riders so makes it a good target radio to to connect to the SR10. The headset connection used on this ham radio is of course a proprietary 7 pin waterproof connection plug.
I'm still waiting for the DIY plug from the SR10 so I can create my own plug for my Yaesu FTM-10SR, but even then, I'll be about $50 in between purchasing the Yaesu CT-M11 for their open ended plug and the Sena SR10 open ended plug and still have to connect them together. If you guys came up with a plug already built for this radio, it should be cheaper and take the risk out of the customer screwing up the connection.
