Question about Cobra 200 GTL DX 4-Channels Base CB Radio

1 Answer

Radio clicks on and off during transmit.

When keying up in either Hi power or Lo power, when I key the microphone, the radio flickers on and off, and I can hear the regulator(?) clicking. This is all in AM mode, I havent tried USB or LSB. I have had the channel mod done, and it was peaked and tuned. I am using it as a base, and using a Tripplite PS 12 (12 AMP) power supply. I was wondering if its pulling more AMPS (more than 12) because of the peaking and tuning. Any help would be appreciated.

    I took Toms advice into another direction. I bought a higher amperage power supply, and it seems to have done the trick.

Hi Dispatcher,

There might be a few things going on here. You say you hear clicking, regulator woudnt be doing that as they are solid state. It could be a relay, some radios have relays instead of electronic switching when you key up.If the voltage is too low that can cause the relays to "chatter", I would look into that first. Can you take the radio to your vehicle and hook it up there ? ( If you are set up for that) just to see if your battery will drive it better.
Are you running a Kicker or modulator? Lets get this sorted out and see what happens,there are other things but lets try one at a time.

Good Luck,

Why does mic key up and shows dead key but will not transmit,just stays on dead key until you release button

What type of radio do you have? Does the radio transmit but no audio is transmitted? It may be as simple as a broken microphone wire. Please give us more information.

Mic keys up dead key but will not transmit

Does the radio actually Transmit? If the radio says it is transmitting but no power is coming out then you may have damaged final output transistors. Please give us more information about the type of radio you are using and the antenna / coaxial cable attached to the radio.

My hr2600 shows error 3 when it is keyed up and does not transmit

0 = Transmitter Timeout timer has timed-out
1 = Transmit Frequency is lower than TX Lockout Lower Limit
2 = Transmit Frequency is greater than TX Lockout Higher Limit
3 = Phase-locked-loop (PLL) won't lock at this transmit frequency
4 = PLL is intermittently coming out of lock during transmit
*If your radio displays error 3 or 4, don't keep trying to transmit on this frequency. The cause of the problem could be low power supply voltage to the radio or the radio's VCO loop needs adjustment. Refer to a qualified technician for service. Contact the installer of the chip first. If, however, you installed the chip yourself, contact a qualified technician for service.

Receives but does not transmit. It is a Cobra 29

There are a few different things that can cause this problem. 1: If it is a power microphone (a microphone that requires a battery). Try replacing the battery. 2: Broken wires that go from the microphone to the plug that plugs into the radio.You can try gently taking the plug apart and inspecting the wires. If only one has come loose, you can re solder it to the pin it came from. If more than one has come loose, find a wiring schematic for the radio that tells which wire goes to which pin and re solder appropriately. 3:Have the SWR's checked on the antenna. If the SWR's are to high and the radio has been being used in this fashion, it could have burned up the transmit finals in the radio. If this is the case, you will need to take it to a reputable radio repair facility to have fixed.

Full power with zero modulation

you possibly have a faulty microphone, if the amp is keyed to transmit and there is not audio to modulate. Try another mic

I got a cobra nw ltd 29 and as soon as mic is connected it starts making like a thumping sound and thats all it does pa doesnt work and it only sends thumping to other radios

Hi there,

It sounds like a microphone problem! I am a C.B. & Ham radio Tech. Try changing the microphone to another one and make sure the Microphone is the right one for the radio. If the microphone is not the right one for the radio it will not work right or when you plug it in it will automatically key up and transmit and the red TX light will come on and it will try to transmit somthing and that would be the thumping everyone hears!! Try that first and let me know if you have any other questions then you can E-mail me at

No Transmitting, no RX sound, but can hear speaker click on...

Hi there!!

The symptom sounds like a bad Microphone connection or a bad microphone!! The Cobra has a built in circuit that wont allow you to hear anyone until the microphone is plugged in and the no transmit part will also do the same. Try another microphone that is wired right for that radio before you do anything else!! let me know!!

Radio stays transmiting after mic released

What happens if you "key up" and "let off" and the transmitter "hangs", you remove the microphone plug from the Cobra ?
Will it still be transmitting or will it stop ?
If it stops, the problem is in the microphone with a "hanging" switch which you can easily clean or replace.
Iif it keeps transmitting while the mike is disconnected, there is a problem with the Rx/Tx switching circuit. This needs further investigation by use of a circuit diagram.

Cant transmit

Hello Darren, Yes it sounds like the mic is wired bass ackwards,,! A cobra 25 mic wiring is
PIN #1- Shield or ground wire
PIN#2- Audio or Transmit modulation
PIN #3- Transmit or Dead Key
PIN #4- Receive Audio.
When your keying the mic, the RX wires are being connected to make the RX work,,,
*** Let me know how you get along with it. Either buy a new mic wired for your radio or you or someone comfortable with soldering needs to resolder the correct wires back on the mic plug,,,Like I said, let me know and have a great day,, Mechanic is back quiet!
