Question about Radio Communications

I have a Connex-CX 366-CE Night Runner CB radio that has just suddenly stopped getting out when i key the Mic. the needle drops to 0, but I can hear myself on the TB turned on and the RB beeps when i key it too, but I can get out to nobody. But i can receive just fine. What could it be?

The overall reports on this radio, which appears to have been discontinued, is that it has a number of problems and needs to be serviced and the circuits aligned by someone with the appropriate skills and equipment. If you purchased it recently, from all reports, see if you can get it serviced under warranty.
otherwise, find a good CB repair shop and have them check it. The likely culprit is a bad transmit circuit. Not a easy fix unless you have the tools to test properly.

SOURCE: how do i find the FM frequency for a Connex

FM is just a form of modulation, not an actual frequency. The frequency doesn't change between any of the modes (LSB, USB, AM, FM, CW).

For example, if you are on channel 19 (27.185MHz) on AM (Amplitude Modulation,) switching to FM (Frequency Modulation) mode you would still be at 27.185MHz, but using a different form of modulation.

SOURCE: Connex 4600 Turbo

Every tech. knows and every Connex owner Knows that once a Connex has been peaked and tuned and also had any mods done to it that the stock microphone that comes with it will not work as it should and then you will have bad feed back!! The best solution for this is buy a good Noise canceling microphone!! Such as an RK-56 or an Astatic 636-L Noice canceling microphone!! This usually will correct most of tghe feedback if not all of it!! And it will also let you keep most of your Mic gain turned uo too.

SOURCE: My friend would like to purchase a Connex CX 3400

These radios are know as what's called 'export' radios. They are imported under the auspices of being a 10 Meter Amateur radio and then through a typically easy modification are made to allow the selection of US CB channels. usually the modification involves plugging in a loose connector inside the radio radio chassis and/or removing a jumper wire soldered to a circuit board. If there is a nearby CB Shop they will usually do this for a modest fee.

Keep in mind that a radio needs to be Type Accepted by the FCC to be legal to use on the CB band in the US and export radios typically are not. Be sure to check the rear label for an FCC ID number.

SOURCE: Can't talk to anybody, but can hear them just fine.

Could be a few things.One as simple as a bad soilder on the board or your voltage regulator could have went out. If you take the top cover off and talk in the mic and its starts transmitting then you have a bad soilder to check the regulator is a little harder and not for just anyone to do.

Its just RF feed back, that's normal, try to re-route the coax, or just turn the FM down, o try turning your modulation down....hope this was helpful....

I have a cx-366ce cb cannot hear talking what is wrong

Is squelch turned too high that it is blocking too many signals?
Otherwise, it could be a faulty cable on the mic as the PTT button disconnects the speaker on the CB and a broken wire can cause the speaker to be disconnected.
