S/rf is too high on transmit on my cobra 29 ltd bt


no matter what s/rf you are looking at it should not key much beyond an s-9 . vr 3 controls the meter. Key the mic and adjust it to s-9 then check you modulation.If you still think you need more then adjust vr 4 .

Rf meter not moving when keying up


if the radio is transmitting fine, then the meter is shot. It happens. You can get them cheap on ebay. Its 2 wires and 2 screws. You need to un solder the old one and solder in the new one.

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!

Cobra 200gtl High Power Transmit problem??


Depending on the type of power supply, radio frequency (RF) energy from the transmitter may be 'fooling" it into thinking that you're overloading it. Check to see if there's any discernible dimming of the meter lamp when this problem occurs, if so, the supply is the culprit.

Otherwise, its probable that the final amplifier transistors are overheating, either they are 'leaky' or not properly attached to the heat sink.
