There is a break in the ribbon that goes from the board to the front assembly. Check the ribbons for disconnected wires, or breaks.

The calibrate needle wont move to the right to set whe trying to calibrate on cobra 29 ltd classic new radio


You have to press the transmit button to get the radio to send a signal that you can calibrate the SWR meter to. If you are pressing the transmit button and nothing is happening then it could be a blown final transistor, a bad switch, bad microphone connection etc.

I have a Cobra 29 LTD the speaker no longer has sound. Can this be repaired?


if the speaker is blown, it can be replaced. If the mic is bad, or has a short, the radio will not go into receive mode. Then you will get no sound from the radio. Try a new mic.

You got your radio peaked? Most likely, however, the pot for the antenna warning indicator is VR6. I always check that after peaking a radio.

Cobra 29 issues


Check D23 and D28. They are polarity protection diodes. It could also be the power knob.

Hi,

Your concern is no transmit and no red transmit led -

If there is no receive likewise, then probably problem in the PLL/VCO section or 9V voltage regulator TR23 (2SC1096) or Zener diode D22 (9.1V).

If the receive is normal, then possibly any of two (2) faults:
1. microphone/PTT switch and/or the mic cable specifically the wire connected to pin# 3 of the connector; or
2. +8V switching transistor TR21 (2SA733P).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
