Cobra 200 GTL DX 4-Channels Base CB Radio - Answered Questions & Fixed issues

https://www.youtube.com/watch?v=a85zMM46Gi8 You watch this video and check your power output specially on those channel at chich not transmitting, if there is no power at those channel it mean that you program out of range radio band frequency, so you check your frequency and correct it.

check the voltage going to the lamps before you do this so that you don't have to replace them . They might just be shorted enough to have the lights go out.

walk it over here and I'll fix it for you. turn the watts to 1.5 watts and check the frequency .

Icepick , there are diode in the radio to allow the voltage to flow to get those lights glowing. If the voltage is not at a specific level then you may have the problem you are describing. make sure you have 13.8 volts of power coming into the radio then check you voltage on T712 to make sure the voltage is ok also IC 5 . Check diodes 68 , 69, 71,72 for correct voltage . now you need a voltage chart. You will have to google it .

I'll sell it to you for what ever you want to pay.

then don't touch them

does the radio turn on at all ? Do you have it on cb not pa? Is your RF GAIN opened all the way? Squelch turned all the to the left?Volume opened about 1/2 way it should be on .if not go inside radio and look for VR that is beside the modulation transformer and turn it all the way to the right . If you have no power put put then you will have to adjust the power out put coil . you will need the service manual and some equipment to check this out. Its going to get expensive but if you feel as though you can't do it then take it to a tech and let them get the headache.

check your voltage its probably incorrect

rv9 for hi power and rv8 for low.hi would be around 32 w and low around 4.

yeah and so does everyone else.

It sounds like the final transistor may be shorted/burned out. If you don't know how to locate or test the transistor you'll have to take it in to a tech. These transistors are usually quite cheap but as to the labour cost it depends on your tech. Usually what causes this damage is a bad antennae match or a bad antennae itself, even a shorted antennae cable. After you've repaired the radio check the antennae and cable first before connecting it up again, then check your match with an SWR meter. Good luck

Open radio up and adjust rv9for am fm high power or rv 14 for ssb for high power,do not use a screwdriver,a matchstick would be better.board information is available from cb tricks.com

try a different mic . your mic may have a broken tx wire.

hi More than likely your pa transistor has blown have you checked it with a power meter if so r you getting the red tx led when the ptt is pressed if so then your problem lies with the rf transistor
replacing rf transistor

• Hi, I can help.

• I have uploaded a pic of the Cobra 200 and labeled each knob/switch with letters to reference.

1. A) Noise blanker - When this switch is pushed the high pitched noises are canceled leaving a more natural sounding receive. Some like it some don't.
2. B) High Power - This button adjusts the power output of your radio. Inside the radio the pots are adjusted for a low power setting and a high power setting.
3. C) Roger Beep - This is a beep heard by the person you are chatting with at the end of your transmission.
4. D) The 10+ KHz - This button when pushed jumps the frequency up 10 Kilohertz to help you better navigate frequencies.
5. E) This is where you adjust how you are going to modulate. CW is for continuous wave or Morse Code. Unless you have a key don't worry about this setting. FM is for Frequency Modulation AKA the HAM bands. AM is for Amplitude Modulation. USB and LSB are for Upper Side Band and Lower Side Band respectively.
6. F) is the band adjustment - Each band (A, B, C, D is a set of frequencies.
7. G) is a dimmer and the SWR calibrate. To use the dimmer push the dim button in a rapid motion. To use the SWR calibrate side press and hold the dim/calibrate button and using the SWR knob on the right side of the radio (L).
8. H) SWR/, S/RF - If this button is in the out position then your meter will swing as usual. Push the button in to measure SWR.
9. I) is the volume and squelch. Volume is what is adjusted to how loud you want your speaker. Squelch you adjust to take out the unnecessary white noise.
10. J) Mic Gain and RF gain - Mic Gain is how much gain you want to your mic. RF gain is how much of the receive you want to pick up.
11. K) Is the fine and course adjustment that you clarify your frequencies with.
12. L) You adjust the echo and the SWR with.
13. M) is the channel selector.
