Question about Cobra 29 LTD CB Radio
No tx and no red tx lite
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.
