20 Most Recent Connex CX-3400hp AM/FM 10 Meter Amateur Mobile Transceiver - Page 3 Questions & Answers

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.

If you must use echo.. please use a dummy load. while adjusting the amount of echo.. you want it to be intelligible to the other listeners.. just barley add the echo effect and it should sound great and not like your in a can or all running together were no one can understand you...

this usually just blows the fuse, check/replace and try again, if it pops the fuse, the protection diode has shorted and the radio needs to be serviced

To recieve signals on 10 or 11 metres with the same antenna is usually without problem, it's when you try transmitting that the correct antenna length is vital. If it's not correct, you can , at the least, get very little power being radiated, and at worst, the power going back into the transmitter and cooking it. If you have to ask these questions, you should not be on the 10 m amateur band anyway.

Check for a Bad, whats called the AM regulator on the back corner of chassis by pwr connector. 2sa or 2sb styles. 2sb817 if available is a good $3 replacement.

8v 1 amp to-220 package. any package would work. just make sure its rated at 1 amp or more..

you should have saved your money and bought a noise toy instead. they just plug into the back of the radio and your coax from the antenna plugs to it.

A qualified cb radio technician can do it.

small watch like battery located behind channel selector

There are many reasons for it to blow a fuse .Putting one in that is higher in amps won't help ,all it will do is prolong the reason it is blowing fuses. One reason could be IC 5 thats blowing them.

yes but you will have to take it to a tech and let him do it because of process to do the repair.

A standard 3300 hp I seen get up to 40 watts peak, normally I would turn the audio pot up all the way never snip anything and deadkey down to 2 watts. Than adjust for forward swing, I also never run a pwr mic. Good luck

first thging to check is you swr get it as close 1.5 as you can if its to high this could be your problem could be as simple as tuning your antenna or installing good mini 8 coax 18ft long only run 1 antenna and make sure antenna is grounded good thats where i would start if that dont work take radio to a reliable shop like communications unlimited in hebron oh have them check it but a good reputable shop not joe blow hope this helps

you should be fine, check your swr's before and after.a swing kit only throws the carrier and adds more modulation. the connex is a good radio to start with,you should be fine, with the mod kit and radio you will never reach 25k on that antenna with this setup. just make sure the antenna is tuned rite for optimum operation(low swr).

the reverse voltage diode protection has gone short you simply need to cut the diode then get down say a big thankyou and hope your CB is alive a tip is to look for a diode like a 1n4007 or 1n4007 just behind the power socket or on the pcb across the + and grounding you can measure it with a multimeter a tip to find a bad short is this set the multimeter to 20ohm range and not beep then you can test youll see the closer you get too the short the less the resistance becomes so you can be sure of the diode to cut... other than this there is usually a coil also on + and - to filter out rf garbage from a cars ignitions etc {not needed now} anyway this small block coil can melt however if this has happened then its gubbed a good test is does it complain before you switch it on or after if its dead short before then the protection diode is gone if you then find when you switch it on it blows fuses then the audio ic has failed there is many more things can go wrong with cb radios i can help so try these things lets see

I'm assuming you mean just the knob, and not the shaft behind it, if it's a D shaped shaft, a slip of paper in the knob will tighten it up, if it's knurled and round shaft, spread the split in the middle open slightly until the knob is tight

you'll have to seperate the ground from the shield and then attach the rx,tx,and ground ,the shild then the ground thats on the shield.
