R58 keeps burning up, after replacing L7,LA111, 3 different LA111. Lifted legs on Driver Final, and Amp, replaced Voltage Regulator, no good. All I did was replace this for a noise, and would not adjust, was over tightened. Any ideas where to start? Thank you, enjoy your day,,,,,

Here's is a real beaut,around 95% Reconditioned,Cobra 138 SSB/ AM 23 Channel,peaked,tuned,standard Wattage, ( BUT ) has a medicine switch,that give it from a whopping FCC li.it,to a max AM,13watts, SSB 23watts or pure DC power. This radio is a beaut,cranks still,even though it's up in age,can't...

Good day ,hello guys, just a quicky, (That's what she said ), I have another Cobra 25 NW LTD Classic,board number (see pic). I noticed it had been mess with,and has different color pull ties holding the harness. I sent a few pics of the switch,now you can see,sticky fingers had been in this...

Hello gentleman and DXer's,I have a Cobra with issues. When going to get my RX and TX,the frequency just sits and bounces around, and will not adjust. I have my Frequency meter on TP or R61,for my RX and TX. I replaced T20,T7, and a blown diode,D7,the PLL has 10.695, 10.240, and I can see me...

I have a Cobra 29 LTD CLASSIC I just purchased, another one? The radio has a board with 2 crystals in it, 14.91mhz and 15.81mhz, along with a 10.240mhz and a 10.695 I assume, but I cannot see it between the pots According to the Cobra parts, is is a 10.695 filter. I would like to know or try to...

Got a good one for you guys, how about a Uniden Lincoln HR2510? You are probably going to tell me it is not worth the time to fix this aren't you? Com on, it looks like a piece of cake inside these covers? I have 4 HR2510 with no Receive or Transmit, where do we start , LOL. I am serious about...

As I hooked up my Frequency counter to another radio from a Buddy of mine, the radios frequency is bouncing all over the place. Radio has no receive and no transmit, of course, it is off freq. I am not sure about diagnosing this radio, as I cannot get this to lock on Transmit freq, bouncing from...

Howdy, question for a buddy of mine, he has a Cobra 29 LX BT, the fancy L.E.D. face plater version. OK, he was doing the TDA2003A, and upon installing the Cap, ( I think that is what it is ), between t he 2 pins of the Audio Amp, the little Cap took off on him and he cannot find the little SMD...

Cobra 25 LTD, the voltage does not change when tuning the receive and transmit on the Cobra 25 LTD Classic. All I hear in the external speaker is the humming of the radio, and getting no response on Oscilloscope when trying to do any adjustments, seems like the pots are not responding to my...

Does anyone have a recollection of what a ISS85 Diode would be, as in ( WHAT NUMBER ) and Voltage.. This is for D20 in a Cobra 25 LTD Classic. Thank yall for helping me out. I don't understand Cobra for having these weird numbers for their Diodes, as I could not find anything on the internet. It...

Hey, I am having frequencies issues with a Cobra 29 LX BT, I replaced the Crystals in the radio, the 10.695 was bad. Now I can get receive, but it is off frequency, can I get a process of how to go about setting the 10.240 and the 10.695 transmit and receive Crystal frequencies on the radio. I...

Hello, can I get a copy of the Sam,s #89, Robyn DG-30 CB, I have one here I found in my Father's closet, and I need to tune it up, it is off. This radio is in super shape, 23 channel, but I think it looks cool. I have the Father to this rig, Father or Mother, I have the Robyn SG-520D Base, I...

I need a pic, ( if possible ) of the SMD Capacitor on the TDA2003 on a Cobra 29 LTD, took it off to replace the chip, lost the cap and don't remember on which way it goes, DUH,,feel like a DUH. Also, I believe this is a 470pf or a 47pf,or 4.7pf, any one remember, I forgot,,,I think 47pf. I think...

I am having trouble finding the values for this diode, goes in a Uniden PC86LTW, just like a Cobra 25 LTD. I am thinking of a IN60 possibly, but not sure. Does anyone have a idea what diode goes in here, Thank you for a jump start on this radio, I will wait for some feedback from any one before...

Can someone point me to where CT2 is on the board of a Cobra 148 GTL, I cannot find, and I want to align the radio, Thank you so much for your time,Mark

For the alignment, I am not able to get the 34 MHz frequency's, it stops around 32.980MHz or so. I tried adjusting for the LSB, AM, USB, and the frequency will not go pass 33.000 MHZ ? Am I doing something wrong or will I need to replace 1 or a few crystals to reach this frequency. Now it is...

Cobra 29 LTD,,D13 Part number 1SV215 Varicap Diode D19 Part number HZ5C-2 Zener Diode D22 Part number HZ90B1 Zener Diode D5,D6,D24,D10,D12,D9 Part number 2-2AP261 Germanium Diode D4, 2AP34A Germanium Diode. Can anybody clarify the real part numbers for these Diodes, I am not familiar...

Lost my green light on TX, is it a possible Transistor? Thanks,,,

Hello,Cobra 25 LTD ST, I have 10 Volts at TP2, where I am to turn it down to 3.5 Volts, the radio is making a Pulsing humming noise, and blew up 3 Capacitors as I wanted to diagnose the problem. Has any body had this problem, I replace both Transformers in the CB, and the CB keeps knocking my...

Hello,I need a bit of help to wire a Shure CB44 to a Kenwood TS-520S. I opened up the mike,and the wiring is there,but the coating of the green and white wire have disintegrated,but I was able to still tell what is what color.I am told to use the green wire for the High Impedance to the Rig. As...
