CB memory resets when i key the mic

[dtcf150]

I have a Cobra 18 WX ST2. When I key the microphone, it resets my channel to channel 9, as if I briefly lost power. It has not done this in the past (I used it for about 7 months). I noticed that I can no longer transmit to get responses from other cb'ers, A few days ago, on the highway, I wanted to merge into a lane and the trucker behind me over the cb to go ahead and merge. I responded to thank him and hey said he cant understand anything I was saying and that I needed to take my radio to the doctor. Does anyone have any ideas as to what is the problem. I use a magnet mount K30 antenna in the middle of a truck bed toolbox. Thanks.

Just a guess, but maybe something's gone wrong with your input power line. It sounds like there's just enough current capacity to keep the voltage up while just listening. When you key the mike however, the radio's starved out and mostly shuts down. Then when you un-key, it's as if the power's just come back on, hence the reset.

Check all of the connections and the fuse on the radio's power feed line. Could be some corrosion has set in recently. Maybe even replace the fuse just on general principles. Again, I'm just guessing from what you've written, but this is the easiest and hence the first thing to check.

Make sure the PL-259 connector on the end of the coax that plugs into the back of the radio is screwed on tight. The outer ring / shell may have loosened up or come off completely.

Like primenumber said check your power connection sound like the radio might not be getting the voltage it needs,good luck .........

Kind of curious as to how this turns out. Please keep us posted. Or at least, leave a note for your next of kin to post something if it goes badly.

***Just kidding!*** Good luck, let us know.

Could be a bad mic also. Had that problem. Use contact cleaner on your mic, should help.
