My radio shows power but its not transmitting out and shows only5 watts on a meter

connect to a meter. if there is rf power on a watt meter at full wattage. then the am regulator transistor is bad. less than $5 part.

You need external watt meter& SWR meter..Change antenna..Is the radio meter keying 3/4 way up to 4 watts?(if not then its not Tx'ng)It could be 10.240 mhz crystal or IF pots(need Frequency counter) Or take it to professional Cb repairmen...

you either bought it used or you played with the inside because if the alc is all the way open then you have been inside it.got a watt meter to turn up the power.you will also need a volt meter. take it to some one that knows what to do and let them fix it.

I would turn do the watts to about 3.5 and that radio should swing.Sounds to me like its trying to but the wattage is stopping it.Experiment with it and find where you want to set it.

Hook radio to a dummy load with a watt meter in line---if no actual power being transmitted radio will not go to cal or show transmit power.

First is check to see if SSB transmits or not==if it does the AM regulator on side wall of radio is bad.

Second with a meter and no power on--test the driver and final for shorts or open.

If one is bad replace both.

let me know what you find.

Um... What?? This is hooked to a switch? CB radio by FCC regulations is only supposed to have a max of 4 watts total output. If you can flip it to 7 watts dead key, you are doing really good. It won't do much more then that. It sounds like its set up to run on a linear amplifier, which cannot have more then 3 watts dead key transmitting into it.

Dead key, and modulation are different. You may have a meter that only reads dead key, and won't see the modulation. This radio is probably swinging close to 15-20 watts. you need a meter that can read PEP, Peak envelope power. Cheap meters only read AVG, or average power, witch will only show your dead key.

7 watts dead key is really good for that radio.especially since stock only has 4 watts. you cannot get any higher then that without changing finals.

at 3 watt dead key, or 7 watt dead key, your modulation wattage is still swinging much higher.

Also, you will get more swing with a lower dead key any way, which is better if you want it to be loud.

Leave it alone. its probably set just right.

try adjusting the L36,L38 to the highest reading on the external meter and then adjust VR10 TO 4 watts. If this doesn't cure the problem, you have a weak final transistor. Good Luck

have you changed the voltage regulaor, or check it first 2 outside legs should red your 13 volt middle around 9

In order to test this unit you will need a power meter with a dummy load. connect the power meter and turn on the unit, key the microphone and look at the power meter it should have a reading of < 4 watts PEP unmodulated and = 4 watts PEP modulated. If you do not have this reading the RF transmitter in the CB might be malfunctioning. You will need a RF generator, a power meter with dummy load, oscilloscope and a multimeter to troubleshoot this problem with. If you do not have or do not know what this equipment is or how it works, please take your unit to a CB repair shop. Thank you, Shuttle83
