The Connex radio is a division of Cobra, and no offense, but Cobras are one of the cheapest radios around. The problem with your Connex is a simple receiver malfunction. The receiver probably worked great until it was put into storage for a long time, you can replace the receiver, or you can fiddle around with the receive gain until you hear something. But you may just want to send it to a radio store and have it looked at, to be honest with you, Connex is a terrible radio, they sound good, but they're terrible radios. Go with Galaxy or Uniden radios, you won't be disappointed.

SOURCE: how to convert a connex

That needs to be done by someone that knows how, theres soldering involved. most cb shops will do it for $free-$10.00... Don't pay any more than that.. there are no parts nor is it hard so they shouldn't charge much.

When i key my connex 3400 hp up the meter drops to 0

If this isn't the result of an incorrectly set switch (ie: the PA / CB switch set to PA, failure to modulate the carrier in SSB mode, set to CW etc.), it is likely to be an antenna / coax connection issue. Double check connectors at the radio and antenna. Remove and inspect for dirt corrosion, etc. Clean up and reconnect. Make sure fittings are at least hand tight. Check for solidly connected antenna mount to the car body. If the type that engages the lip of / or a body panel, make sure it isn't rusty. If a magnetic type, try placing on the center of the roof (if metal & look for evidence of water entry into the base of the mount) Check the entire length of the coaxial cable. Look for places where it may be damaged from pinching between body panels. Crushed, chafed, and cuts in the outer jacket indicate a problem with the way the coax has been routed. Make repairs / replace as needed with thinner diameter coax if needed or reroute away from pinch points. Lastly, check and adjust your antenna for minimum SWR with a meter. A match of 2.0:1 will be required to prevent damage to the radio while transmitting. A 1.1:1 match is ideal, but under most circumstances. a 1.5:1 to a 1.8:1 match is attainable with a little bit of effort.

I hope this helps & good luck!

Fix my connex 3400 hb sideband button

Hi there, if you are talking about the Connex CX 3400 HP there is no sideband or SSB on this radio. It is only AM and FM 10 meter Ham radio. Many people do modify these radios to include the 11 meter frequencies which is the CB band. Maybe knowing the actual bands and their frequencies will help some too this radio does have 6 different bands ranging from (Band A. 28.015 thru 28.455) (Band B. 28.145 thru 28.585) (Band C. 28.115 thru 28.555) (Band D. 28.085 thru 28.525) (Band E. 28.055 thru 28.495) (Band F. 28.025 thru 28.465.) I hope this will help you. Bob

My sunroof will not close. I can hear the noise

It sounds like the switch has gone bad or that there is something wrong with the track. If you look on the inside of the sun roof you should be able to see four screws. These screws hold the sunroof in place and to the track. Take those screws out and then the glass. If you look down where the track is when the glass is out and push the button to open and close you should be able to see the track move. If you cant see it move when it is supposed to open pull the switch and see if you are getting power to the open and close side of the switch.
