RF gain or volume turned up all the way?

astatic 600.It has 3 windows for SWR, Power handles up 5000 watts and modulation cost about 120.00

buy yourself an astatic PDC-5 antenna matcher and use it to get your match to a 1.5:1 but before you do that is your antenna one that can be tuned by sliding it up or down if so and you can't get it any lower than 3 then get the PDC5 only about 24.00 plus S&H

You need at least 8 amp power supply

Try www.ebay.com type make and model and go through the list.

turn rf gain up and the mic gain down until it stops squealing.

You need to mention what kind of antenna...a car mount or home mount.Here is the owners manual: http://www.cbtricks.com/radios/connex/cx4300hp/graphics/connex_4300hp_om.pdf

I hope by now you have sent it back to be repaired or found out what the problem is.

you have a short circut some where..use the eraser on a pencil and push solder joints...

REPLACE THE TINY BULB...DUH, use a meter to determine positive a neg on supply, hook up backwards and you may blow the bulb..

yes,also SWR may be to high.

Check cables and connectors. • check antenna SWR, A good SWR ranges from 1.2 to 1.5. • check power output.

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

Take it to a good cb shop radioactiveradios do really good work on connex radios

sounds like a bad ground try moving your antaneas maybe or if you have wippes or firesticks tries trimming then

hows the SWR ?the ground? the antenna itself? on the inside check the final.

mic may be wired wrong, be wrong impedance for this radio

Oin 2 may be grounding, or the relay contact is not opening to break the circuit of the recieve section. Or your SWR is so bad that what you are hearing is from energy transfer alone and copper corrosion can act as the detector diode.

If no power, check the red and black wires inside the radio, there should be a black diode right is near the leads often shorts if wires are hooked up backwards, also look for an open foil on the printed circuit board.
