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.

Cobra 1000 will not receive or transmit.

Sounds like a problem with the VCO / PLL Circuit since nothing happens in RX or TX. Check to make sure you have the correct supply voltages to start with and also check to see if you have 10.240Mhz. Use the service manual and go through the PLL/VCO alignment section. If anything is missing then you at least know where to look.

Is the meter moving on key up or another radio transmiting to it?
Switch for S/RF, CAL, SWR.........set to S/RFRF gain knob full clockwiseSquelch counter clockwise
If just audio is missing my be Audio Chip i think IC3Bad Crystal or solder to it.May be bad PLL chip any of these 3 could affect both TX and RXI do not suspect mic as there would still be audio just at low volume on receive.

Have Cobra 29 LTD CB Radio w/ bluetooth. Power comes on. Does not receive or transmit. What's wrong?

Sounds like the PLL circuit....... no channel synthesizer will kill the transmit and receive...... bad crystal or IC could be at fault or if someone has attempted to add more channels could also be cause.
