We soon started riding with a GWRRA Chapter, made great friendships, fun rides, but I relied on hand signals and the rides were "quiet". Others had CBs and I could tell they were passing information that I often didn't get. I wanted to add a CB, but dang, they were expensive used. It was the late '90s. I doubt you'll find even a used GL1200 CB now?
A fellow sent me a schematic to build an "integrator" to incorporate a regular small 40 channel CB to the bike, duplicating all functions. I mounted components in a cast aluminum project box that had a lid with O-ring seal, I velcroid it on top of the CB, I made a aluminum frame and added small suction cups to it, and a strap to secure it on top of faux tank. I made a removable cover of tinted plexiglass to shed water (rain), I tapered the front to let me open the door for gasoline. I used a momentary button in small plastic box velcroid to left reservoir for PTT button, I used a CB-AM/FM combiner to run CB ant off AM/FM, I added power wire to CB from Accy terminal, I put plugs on each so I could remove CB when not needed. I used this for 20 years, great setup. I added a quenching diode across the PTT leads to the integrator's 4PDT relay. There is also a 1/8" mini plug that plugs into the CB's external spkr output. The antenna combiner is under the faux tank, over next tyo overflow tank, but it's CB lead with PL259 on it is long enough to come out front and attach to the CB. The power cord is simply tucked down into bowels of fairing on the left side.
In use, it works great. I often got compliments that my CB talked as good & often better than the factory units, I often heard conversations of other groups before fellow group members. I had SWR set just right. If the AM/FM/Cassette is on and either of us said something, or if CB traffic, MUTE even worked as it should as the CB ext spkr talks to the MIC circuit of the Type III.
It occurred to me, someone else might want a copy. I used a small Cobra CB I bought at a truck stop for $30, I carried the mic in a plastic bag as it's not used. I gave the CB & integrator to the bike's new owner when I sold it. Radio Shack has no stores here now, I miss them, but shopping the net should get the parts.
