Re: cobra 2000GTL

Hello wood butcher,

This sounds like a capacitor is not discharging fast enough and has enough residual voltage stored to continue to power the display (to a point). I would check the capacitors that are connected to the vcc of the display matrix and also check to see if one of the resistors has not increased in value due to a possible thermal event.

Tell me how this works out,
Thank you,

I'm looking at a price range somewhere in the area of 40 - 120 $$ to buy them new. If YOU can fix them without getting a tech involved then go for it but you will need a frequency counter that covers the range and they don't give them away cheap and the repair cost wouldn't be cheap either. I would buy another pair.

Cobra 2000gtl no sound comeing out but will talk on am and ssb can you help

Because you have transmit, more than likely your audio section is OK as much of it is shared with the receive side. A final test of the audio section is to check out the PA function. If it works most of the audio section has been tested.

The signals for the meter movement and receiver sound are developed in the audio detector circuit (diodes D21 and D22) just past the I.F. stages (Transistors TR16, TR17, and TR18). I have seen these diodes fail. They are frail little guys, but are inexpensive. I would recommend replacing them first. Pay particuliar attention to which way the band on the diode is positioned and limit your soldering time. If that does'nt rectify the problem, (no pun intended) you can look at the transitors.
By the way, MOVE that second test radio farther away or you could overload the front end of your Cobra creating even more problems. Good Luck, 302

No front panel lighting

The "nightwatch" lighting uses an EL or electroluminescent material that does degrade with age. If the radio is old, then it may be lighting very dimly (check in a dark room with the dimmer at full bright). The material is connected by a ribbon to a special high voltage pulsed powersupply that runs at about 500 volt. If the power supply is working then a new face would be in order or a new radio. If the powersupply is not working it may be repairable but requires working with surface mount components. Either way, it is NOT a simple lightbulb fix. I have successfully repaired and do stock the smc components to repair but cannot get the faces through cobra ($$$). More info? Contact through
