I have a connex cx-4300 hp cb it will receive but won't send how do I fix this problem

Is there any RF being transmitted, to a nearby radio. also does the TX/RX led change.

There are many scenarios on this..

Loose/cold solder joints on the board.
loose diode on solder side of the IF area..
Bad RF transistors from High SWR..

if you can provide more info.

Connex 3300 hp

no its not the problem but it doesn't help..first, is this a newly purchased radio or did you get it on ebay . if its new send it back its still under warrenty as long as its not to old . iIf you got it on ebay , you're screwed. You can take it to a CB shop and they will fix it for you.I could fix it but I don't have time to explain the procedure .

Connex 4300-400 how many amp can they pull

easy way to find out.. is use the wattage divided by the voltage used will give you amp draw.

so if you in a vehicle.. most are either 12-15 volts.
the radio in theory say its doing 400 watts.
400/12 = 33.3 amps
normal cb that can do 12watts your looking around 1-2amp draw.

What do you think is wrong with my connex 4300 HP, I turn it on it powers up,but no adio it has static. It seems to have a dead key and swing. Any ideas? Thanks Jim

You will need an SWR meter to check your antenna. FIRST.
I would find help at a local cb shop.. They SHOULDN"T CHARGE to help you SET the swr. only if you need a part or something ..
I don't charge to SET SWR"s .. only if the cust needs a insulating washer or another antenna, or new coax, so-239 etc... I would be glad to help you.. let me know if we can CB Shop Temple, TX
Any shop shouldnt charge you just to see if it works!!
