Try to hook up cw key but it keeps beeping

There are a few possible reasons why your radio might not be transmitting in CW mode. One possibility is that the keyer chip has gone bad. Another possibility is that there is a problem with the power supply. If you have a multimeter, you can check the voltages to see if they are within specification. Finally, it's also possible that there is something wrong with the antenna connection. Make sure that everything is securely connected and that there are no loose wires. I hope this helps!

I have had this occur when either my keyer paddle or cw key is pressed as if sending. In other words you are in transmitting mode.

The ic-735 has to have the keyer option to use with a paddle, if it doesn't you will have to use an external keyer with it

Sounds like you need to monitor what's going on at the battery. Hook up a volt meter to see if it's charging. Check and clean all connections / plugs. Check connections at key switch. Look over all wiring for shorts or broken wire. Disconnect everything but motor wiring to narrow down the problem. Starter drains battery faster than it can recharge.........
A dead battery will mess up a charging system and a bad charging system will kill a battery.

Ur High Voltage is dead.The FBT the flyback transformer is dead.The big block of plastic with a red wire with a cap hook to a CRT(tv tube).Replaced the FBT get power back.

Hook the 12v memory to a constant power, like the cigarette lighter, or parking lights(red I do believe) The yellow one is key powered, so hook that to something that only powers up with the key on. The black one is a ground, that should be obvious. As far as speaker leads, you can take the door panels off and see what wires are connected to the back of the factory speakers. Hope this helps.

sounds like you got a good radio to practice on . If it was given to you then you have nothing to loose except what ever you put into it. try hooking the speaker jack back up, see what it does??

If this is a stock cobra 148 gtl 40 channel am plus side band, they don't to my knowledge come with a built in r beep. Some roger beeps are instaleed through the transmit circuit on the mic, so if not in the know Don't try to fix it.Some microphones have a beep built in. I used to install beeps on these radios using the pa/cb switch to turn them on. also try the nb switch or the swr/rf switch.

Unplug
hold down energy saver key
plug back in
scroll down to ALL JOB CLEAR
set
machine will reboot

no i'm looking for a cobra 148 GTL DX ok
