Weak CB transmission.

Post by larrythecabinetguy »



2002 GL1800 with 36000 mi. My CB talk range is only about 100' or less. Very clear and loud to other riders under 80'. Do not appear to have a reception problem. I have cleaned all connections of the antenna and connections with no noticeable improvements. Have switched antenna with other bikes that are working well with no improvement. Have cleaned the talk switch lever, which was sticky when I bought the bike 3 months ago and it appears to be working well. Have only checked it on channel 1 but will test it on others with a buddy in the next couple of days when he is free to come over. Any help appreciated.

Based on your description, I would assume it is NOT transmitting the full 4 Watts of RF power. Probably damaged the output stage of the CB, the only way to really check that is to put a power meter and dummy load on the output of the radio. If you have a friendly local Amateur radio person they can probably check it for you. Don't know who repairs these units, but sounds like the transmitter needs repairing.

Ok. As with my post about the acc curcuit going out, this problem appears to have resolved itself. I had cleaned the talk switch with contact cleaner a second time, without removing the cover, and wednesday a buddy with a gl1500 with whom i ride often came over and we tried the cb before a trip to bike night in New Orleans, about 60 miles out. Before we left i had very weak and static filled transmission even next to each other at stop. Vitually useless. Still receiving well and the roger beep was working well. When we got near the destination, i did a radio check and he said i was louder and clearer than i had been since i got the bike. I am convinced the switch needs further cleaning but i am reticent to do it because some one has gauled the screws and im not even sure i can get them loose. I will try another spray of cleaner and qtip. I will say that the drainage from the cleaner comes out pretty well soiled each time i do it and i play with it until clear but i am also sure i am not doing a thorough job on the contact area, as i cant even see it. Time will tell. Again.

Is it weak for everyone that is receiving your transmission? Or perhaps just for one other person?

I encountered a bizarre problem with a friend who has a GL1800 and factory CB. We went out riding, him on his GL1800, his wife on her Virago with a J&M CB, my wife on her bike also with a J&M CB, and me on my GL1500 with the factory CB.

Everyone could transmit and receive perfectly fine to everyone else - except for the GL1800 to me. Whenever he transmitted on his GL1800, I could hear a very clear carrier, but the audio was very weak and distorted. But it was perfectly clear to everyone else! We tried riding away from each other, thinking that maybe the strong signal was overwhelming my receiver, but it made no difference. I could transmit to him perfectly, but I could not receive clear audio from him.

I later did some diagnostics, on both my GL1500 and the GL1800 CB's:

- Checked SWR and power output of both radios. SWR was perfect on both, power output was near to maximum (4 watts).
- Checked frequency of both radio transmitters with a frequency counter. Both radios were right on frequency, well within tolerances.
- Checked output of GL1800's RF signal on an oscilliscope, carrier was strong, and well modulated.
- Out of frustration, checked audio cables and headsets. No difference.

I never did figure out what the problem was, and it still exists today.
