Re: limited cb radio range on Kenworh t800 truck
I recall problems grounding the antenna on those kw's. May want to try a no ground antenna. Also the stock coax that comes with the truck sometimes gets broken or pinched. Go to a good shop, replace the cheap coax and grount the antennas.

Since the radio cannot transmit on Weather bands, there is no need for the radio to detect if it is transmitting when receiving weather.
In CB mode (on CB channels) the radio will mute when transmitting. So... a guess is that it is muting, or transmitting all the time in CB mode. Check for a mic problem by removing the Mic from the radio ... if it receives CB with no mic connected, then there is an issue with the mic. Otherwise, unless the unit is in PA mode (public address mode) it is likely something internal and beyond the scope of this service.
0 = Transmitter Timeout timer has timed-out 1 = Transmit Frequency is lower than TX Lockout Lower Limit 2 = Transmit Frequency is greater than TX Lockout Higher Limit 3 = Phase-locked-loop (PLL) won't lock at this transmit frequency 4 = PLL is intermittently coming out of lock during transmit *If your radio displays error 3 or 4, don't keep trying to transmit on
this frequency. The cause of the problem could be low power supply voltage to the radio or
the radio's VCO loop needs adjustment. Refer to a qualified technician
for service. Contact the installer of the chip first. If, however, you installed the chip
yourself, contact a qualified technician
First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit. If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es
You want to be able to transmit to the Coast Station on this frequency I assume. The Coast Guard monitors channel 16 at all times. This would be the primary channel in the United States. Your radio is VHF Marine Radio and has a built in frequency range of 156.050 MHz to 163.275 MHz. There is no need for a modification. This is a duplex frequency. What that means is you will transmit on one frequency and receive on another, while on channel 20. You will not need to transmit on 161.600. Turn your radio to channel 20. When you transmit, you will transmit on 157.000. And when the Port responds to you your radio will automatically receive their signal on 161.600. So if you are trying to figure out how to communicate with the port authorities then for that frequency turn your radio to channel 20 and you will be able to communicate with them.
its the coax. i had this same issue. i thought a bought a great strand but, it was very poor in design and it developed many breaks over time, reducing its transmitting ability. I would also check the mic wire and head connections as well. this is a problem spot at times.
no,its in the radio.i have had a lot of radios,and i have had several with just too much noise.its in the radio.i would not go by what a trucker cb shop says.contact company,or try and sell it and start over.i have had to do that also.
