Ladies and Gents,
This is a stupidly long write up on an autocom modification which someone in the distant future may find useful...
I recently acquired a ptt switch for bike to bike use with my autocom unit. With the clip-ons on my CBR however, there were next to no options for mounting the switch in a convenient place to operate with my clutch hand. After a quick double check on the rules I found out the passing light switch is not an MOT requirement and decided it was in the perfect place to operate while riding...this is when my selection of hammers came out and I went to work.
Firstly I opened up the autocom switch, held together with a single screw and removed the guts. There is 3 way toggle switch used to change the settings from VOX, PTT and constant transmit. I have read on quite a number of sites the toggle switch can easily be knocked while riding to either VOX or constant. If the latter occurs, fellow riders will not be able to override your transmit and tell you to shut it off...and if you enjoy singing to meatloaf while you are riding, the consequences could be severe. I don't sing to meatloaf, but I do sing badly, so I opted to do away with this toggle switch altogether, and just rely on the ptt function to broadcast. There are a number of wires looping from switch to switch in the unit, mainly blue ones, but there are just three wires coming into the switch, one blue, one red and one black. The red and black ones are the only two you need worry about. I used a soldering iron to separate the three wires from the switch unit, then stripped back the red and black wires (you can cut the blue wire back completely).
