Yes, I do, I tried to tune this last night with no avail, I will give it a try again, but with no voltage change, I watch my Peak to Peak last night and went off of that, and nothing, I even turned it on this morning and still nothing. You van hear the hum or a sound of a speaker when it is just...

Hello, thanks for the possible repair, the only thing is, on the Oscilloscope, I do not get any voltage or peak readings, the peak may move 1 Millivolt, but the rest 9f the cans, both RX and TX, when u go to adjust that can, no voltage change. How do I align this when you have no voltage change?

Hey, good idea for a CB shop, sell CB parts from your living room, I like it. Who would think of something like this, oh, someone who likes to stay home and sell electronics, this Dude is on top of his game. Nothing like getting a CB final in the middle of nowhere, gotta love this guy...

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...

I am so sorry and embarrassed, I was looking at the manual for a Cobra 25 LTD with the weather band in it. As far as I can tell, yes, D20 takes the IN4148,and in this 25 there are only a handful of Diodes, the one with the weather bands takes a boat load of Diodes. Well, I appreciate all the...

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...

Sorry for the late reply, the 10.240 Crystal was bad , I could not get down to that freq, installed the new one, and bingo, had it in no time. Then I got the POP, and everything just started to work, had the tune the transmit6 a bit, and receive was pretty darn close. Thank you for the tips...

Hello Tampa,,it was the 10.240 Crystal or a bad solder. I replaced this Crystal, and reinstall the other Filter or Crystal, it has the 10.695 writing on it, either one it us back in the board. Now the 10.240 and the 27.1185 stays one, may drift a few re adjusting the receive, but not as bad as...

One more thing, nice to meet you Rob, I just looked at your first name on the ARRL website. I appologize if I have it wrong, there were only 2 with that call, and one was not registered, so I figured this was you left,LOL..I took a stab at it and called you Glen, and I am sorry if I offended you...

Yes, I have all the necessary equipment, I will have to look again, I am certain when I took that out, it had a 10.695, and I kept it separate from my other Crystals, but this has it's own markings on it. I added the pic of the Crystal. I am going to finish the yard and get on the radio, I will...

I believe the name is Glen, thank you for the link, I have been through that alignment, what I need is,the way to set the frequency's on the Crystals. I know if you to the alignment that the frequencies get really close to the settings, I was wondering if there is a different way to do this if...

Yes, It has 2,10.240 and 10.695,this is the LCD screen 29,with the Bluetooth,and you can change the colors of the front panel.It just seems that I cannot get the frequency to stay. I peak out the first 2 cans, set the 3.50 Volts,then align the receive, and then go to the transmit. I do use a...

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...

David, thank you ,l I did a quick eBay search and I did not find this issue, they were all sold out of that issue. I will go look again, or I will go to Sam,s web site and pay the $20.00 for the download, then I can print the Service Manual after I get it. Thanks for the heads up, I thought...

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...

Thank my friend, I am thinking it is the 47uf, that is stuck around in my brain for some reason. I have a boatload of SMD's, I been rtebuilding HR2510 PLL boards, as I am stuck with 3 of them and and all 3 don't work. I need to get on them, do you know much about these? I am having problems with...

New York to Virginia coming into Chicago area

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...

Thank you very much, now I will have my eyes checked? How in the world did I miss that,,WOW, where is my mind at...... Thank you very much, now I can continue with the radio, have a great day, appreciate your time,, mark, KB9GTB,,,,,,,,,,,ENJOY
