Connecting a Cobra 29LTD to a Pyramid PS-3KX 13.8VDC Power Supply


Hi. I'm very new to the world of CB radio and have a slight problem. I purchased a Pyramid PS-3KX 13.8 VDC Power Supply alongside my Cobra 29 LTD Classic Radio and obviously I need extra parts to connect the positive and negative wires directly into the power supply. I'd like to know what these parts are and where I can purchase them ASAP. Thank you.

The wires should just attach to the red and black terminals on the radio, strip some wire unscrew the terminals a little wrap behind, and tighten again. Good luck! Or buy some banana plugs and they will plug right in the front

It would depend on the vehicle. For this model you need a power supply and a ground. You will also need an external antenna.

Bought a cobra lx le from sparkys cb shack. using the radio as a base station. with the radio turned off , when i turn the power supply on a pyramid ps-7kx the radio face plate lights up for a couple of...


This is normal for the LXLE's. The new circuitry power the new face plate uses a small high voltage transformer and if power is applied to the receptacle on the radio it is drawing some current. When the power supply is turned off or on with the on/off switch on the LXLE turned off there is still a spike of current going through the radio. Not to worry, it will hurt nothing. If this is truly a problem, someone could probably design a little diode circuit to stop this issue. I would if I could but am not that smart.

Cobra 29 ltd when powered up error Y can anyone help me


Hi and welcome to FixYa,

Often an error code "Y" would indicate test/diagnostic result of the antenna. A communication equipment thus equipped would test the SWR and display this error code if:
  • no antenna detected; or
  • SWR of antenna is way too high.
Although am not familiar with the version of a Cobra 29LTD with this type of display. Could you pls post back the exact model of the radio, normally there would be two (2) more letters after the LTD something like Cobra 29LTD BT.

Good luck and Thank you for using FixYa. Happy Holidays.
