older 2510.no RX or TX??

S

slim cdx285

Guest
she lights up,displays OK;there is audio present(hiss sound from speaker,in RX mode).TX icon on display doesn't show at all.

there is NO power or modulation in any mode whatsoever.

there is NO RX noise(other than hiss) or signal strength on the meter.

TX button on the face of rig won't key it up either!

can someone point me to a good starting point?

I haven't tried for audio at the PA jack yet.don't believe it's

relevant at this point yet.

thanks to all!

Well, I would start with the regulators.

There is a 5v and a 8V on the Micro PCB and there is a 8v on the left side of the chassi.

Left to Right.. Input - Ground - Output



Also check the lil blue Kidneybean Xtal next to the Microprocessor.

I would Clean the glue/epoxy around it to make sure the PCB traces are intact.



Also I would check for Power to the Micro and the other IC' s on the Micro PCB..

See the Voltage chart on my Website:

  • @ kingmudduck:
    So I have a cobra 138xlr and the meter dose not work... It dose not key up and signal dose not work.... It is not stuck it the meter moves freely. now wires are resoldered on both ends...So now that do I look at. Could it be a diode or a transistor?
