OK, I'm not talking about a blown protection diode or anything normal here. I hope. A guy brought me this radio asking if I could fix it. He said that when he turns the key off in his truck then turns it back on the radio resets back to channel 1. It sounds like something that some older...

Hi all. Been a while since I've been around. I picked up another radio and got a non-worker. Maybe I should quit buying these things at yard sales. LOL. I put it on the bench and fired it up. RX is good. Key the mic and found RX/TX light functioning. Look at the meter and I have no output...

This is an odd one to me. Hoping someone can point me in the right direction. I used another radio and I hear that the cobra 29 LTD chrome is transmitting. I also see on the meter that I'm getting RX from the other radio. When I turn the radio on I get a pop so I know the speaker is good and...

That pretty much is it. I found that T1 on this Cobra 29 LTD Classic is bad and I need to buy a replacement. Part number EI-28. Anyone know where to buy one? I know its bad as I took one out of another working radio and swapped it out and it came to life. Audio once again. But I'd like to have...

Hi all. Picked up this Uniden 68 and used it for a couple days. Its a used radio. Got it for pretty cheap. The other day the RX died. So I took it out of the truck and put another radio in the truck. Same mic and power cord. Anyways, I've got this Uniden home and injected a signal into the...

Picked up a Uniden pc76XL for 10.00 bucks. I talked him down from 20.00 bucks because is stinked like burnt components. Got it home and found the final plus R123 toasted. The final had a hole burned thru it. So I dug up a parts radio Cobra 29LTD and pulled R123 to replace the resister and R56...

No, Seriously! not me. He drives for a rock hauling company that has cracked down on drivers for running big power radios in the trucks. so i sold him a favorite of mine, Uniden 66. i got a few of them. now hes wanting it to be louder. I told him to turn the talkback up. It will feel louder...

If the right combination comes along from your recommendations I'd buy very soon but I haven't bought new in a long time so I need some help finding what I want. To start with, I'm a truck driver. I drive a 2017 Kenworth so I only have room for something that is no bigger than a Cobra 29 w/...

I've got the service manual. Anyway, what I'm trying to do is align the TX and RX. According to what I read in the manual, you can adjust the RX frequency but I'm not seeing any way to adjust the TX on LSB. And the RX is adjusted with two pots? Can anyone explain how this is properly done? The...

Got this older Cobra 29 for free. It had a broken leg on the audio chip so I replaced the chip and now it works. So not much into this one. Someone had molested this radio in my terms. Put a T.B., Echo board and noise toy. I've managed to get most of it back the way it should be except for the...

Ive got a couple scrape galaxy cb radios and a few old cobras and got cobras working. Want to know if the echo boards from galaxys can be installed in coberas and if yes, some instruction would be nice. Ive installed many aftermarket echos in cobras but never tried this. Can you help?

Im going to be buying a 5/8 wave vertical and want to put it anove my 3L Steppir. Im thinking ill put the ground plane elements at differant angles to the steppir to cut down on the reaction between them. But what id like to know is anyone who might have this same configuration can tell me the...

My W58 came off the roof pushup pole one time too many and its time to replace it. Been looking at the SPT 500. Had a few questions for the antenna pros on this site. Ideas I've had. Would like to know if what I'm thinking will work or is correct. I'm not a person with lots of antenna knowledge...

THINKING of selling my MK4. In excellent condition and working 100%. I don't have the OEM mic any longer but the radio is 100% original besides a few replaced tubes. It is used every couple weeks just to keep it working well. If I was to sell it would there be any interest in it? I see a few...

Now that I got a good working mic. I now what to make the MK4 Ping. The older versions MK3 and the 2 had a cool ping/squeal sound when you keyed up. from what I read it was a feedback or something between the RX and the TX not stopping and starting quick enough. But not too sure. I did some...

Well all, i picked up a golden eagle mark 4 the other day for cheep. Its a 9.9 in looks and it works just fine. I also bought a banana style mk3 mic. I wired the mic for the radio and i got tx and rx and audio but i also have a squeal as if the mic is to close to the speaker. Feedback type...

I'm trying to locate a SERVICE MANUAL for the Dentron MLA2500. All I can find while searching the web is an Operation Manual and computer viruses. Any have one or know where to locate a DL of the Service Manual?

I have a Cobra 29 Philly model and on channels 1-7 it is fine but when on channels 8-40 its off freq by a lot! Like channel 19 is 26.9378 and channel 31 is 26.9275 Very odd!!! I'm guessing this is an issue with the PLL chip. Can someone else give me an opinion if I'm going in the right direction...

Bought this one and used it for three weeks in the mobile. If you look up posts I've made you can see I was getting good reports on AM and made a few SSB contacts too. SSB is great but I'm just wanting something else I guess. Spend most of my time on AM. Comes with everything it came with. Its...

Got a guy I work with that wants more power. Doesn't everyone. He bought a new 929 and ordered this stinger board. According to the specs it should be able to get up to 100 watts. Yeah right, we all know how they stretch the truth on theses things. Anyway, I didn't mount it in the radio but did...
