2009 Ultra Classic CB issues......

Receives transmission not too clear/crackly.
Does not send transmission.

Do I need to change the cb module ? What tests can I do ?

 

Check The ground. Check the antenna, including measuring SWR's. If it is neither one of those then you will probably have to replace the unit, or take it to a CB shop if you can find one. .

 

My experience with non Harley CB's is to check the Mic.

 

If you are using the boom wired headset, make sure it’s not the cable. Wiggle it around some to see if it changes. Then switch to receive through the speakers. If it improves..it’s the wiring.

 

If the transmitter is keying with the PTT switch and the squelch is working, the receiver/transmitter problems are usually related to the antenna/coax. You need to start with checking the antenna SWR as was suggested. Good used SWR meters are not expensive to purchase and are easy to learn how to use.

Is it possible that the broadcast radio and CB antennae were inadvertently switched at some time? The broadcast radio stations will work great with a CB antenna, but the CB will not work with the radio antenna and the transmitter and possibly the T/R switch will be damaged, and the damage can occur the first time the transmitter is keyed if the SWR is too great.

 

As skinman13 stated, check your squelch settings first, then check your antennas.

 

Looks like its an antenna issue. It has shorty antennas on it, I put my non-shorty cb antenna on it and it worked.
I ordered 2 non-shorty antennas from ebay, when i receive them we'll ride and test.

 

It has to be a CB antenna and you really need to check the SWR if you are replacing the antenna.

 

I see this is from a month ago, but i will kick in some info too. SWR's are the most frequent problem with transmitting and receiving for CB radios, too high and they will burn out your transmit circuit if used for any length of time. After 50 some years using CB's I have found this to be the main thing to check first, and your antenna is the cause of high or low SWR's. Oh, and the higher the antenna the more range you will have, most of the shorty antennas only have a range of about 3/4 of a mile, where the whips have a range of about 1 1/4 miles. Hope this helps someone. Remember, for transmitting and receiving problems always check SWR's FIRST!
