I don't know who your supplier is but if the 520's are knock-offs or imitations that could play huge role here. http://www.vishay.com/docs/91017/91017.pdf

You could try upping the bias of the driver to 3.6 V and the bias of the final to 3.7 V, see if the power comes up, or if the final section just gets hotter! If anything pops, i'm not responsible. Experiment at your own risk, I assume no responsibility for what does or doesn't happen. The...

Hey no worries brother. I just want to leave you with one more tid-bit, I feel it is my duty, because I don't know when or where this radio will be used.. From the comment section, by OP of video: This inherent design flaw is why my EPT3600xx radios sit on the shelf unused. To emphasize...

That's interesting because I don't see R249 mentioned anywhere in the EKL Fet papers. Try this on your test bench, of course use a dummy load: re-install R249 (Limiter) or don't, & add a 1N4148 diode in series @ R238, banded end towards PC board (left side if I remember correctly). See what...

I don't believe so.. I think the radio is doing what is supposed to do, as you increase the carrier the peak output will come up with the carrier, as long as the limiter/AMC is intact, that is the "brick wall" you are seeing, the AMC is attempting to reign in the radio so it doesn't...

I don't want to be offensive so please don't be offended.. but... In a properly configured radio you aren't supposed to see full swing output from 1-2 Watts, that is a separate modification and not one I recommend unless you have a lot of time on your hands and an oscilloscope. "But, LeapFrog...

https://www.gammaraygraphics.com/mobile-radios.html Sells decals for your radio, in virtually any design you want, even custom made, personal ones. You can find chrome covers on eBay (but they seem to scratch real easy) or even vinyl wrap the lids of your radio for a custom look, seeing as how...

Hi Kellin, welcome to the forum! I've never seen a radio from Mr. X CB Shop in person, but from watching his content on YouTube it looks like he specializes in the "llamadores" type of mods, which seem to be audio clips, housed in a noise toy box, wired to many switches. The radios generally...

That depends on what kind of "modification" and who performs the work. I'm not sure what mod you are referring to. If it is the RWOB mod, then I found this on google: Usually SSB can still function, but if the radio gets "butchered for AM", in the process SSB can suffer, removed limiters in...

711 don't build that PCB and expect it to function correctly without some minor modifications, that is a very early PCB, one of the "Alpha" builds and that design is not printed anymore. But with enough time and a solder iron you can make it work, just warning you that, that PCB has errors. ;)...

Yes the LX is basically the same radio as LTD beyond the bezel and weather feature.

*throws up in mouth a little* probably out on probation by now, the "system" is broken..

One more thing, before I create the dedicated thread.... Little over two years ago I couldn't explain what a squelch function was, I had zero experience. I have had no formal post-secondary education, I don't claim to be an expert. I have not had a chance to get my tech license, though I'm...

Yes, no marketing going on. The schematic is being released for everyone. I am typing up a basic install procedure, and a F.A.Q. page. I don't think CB Phreaker is trying to market this either.. I asked him about that some time ago, I don't think he even has any PCB's set aside "for sale"...

I like that NPC board, it is a thing of beauty! And CB Phreaker's board, is really high quality, he made the holes just big enough for the leads, nothing sloppy about his work! Very tight, and very clean! I'm typing up a description of the modification process. This is from my experience and...

That video is not my creation, that was CB Phreaker's work. I am still waiting on regulators to arrive, so the 24 Volt power supply is just sitting at the moment. Once I have it running on 24 Volts I will make a video hi-lighting the details of what is involved. CB Phreaker apparently doesn't...

I don't have shills. If the community disagrees with you, at large, then maybe, just maybe, it is time evaluate yourself. "My reality", please for all the public forum members to see, attempt to describe my SUBJECTIVE state of reality.. please try, i'm waiting for a laugh. This video from...

You can imagine what you want to. You seem to spin your wheels all over trucking and radio forums, I should bypass you. Not all radios are designed the same way, remember that. You must be too busy pretending to know what is going on in someone else's head to acknowledge this simple fact. I...

No one sinned OldTech03. Forgive me for not getting technical in my post, Kopcicle did a great job in his post. I welcome these kind of threads, but who am I.. In the beginning all I knew about modulation was "you want forward swing", and all the locals made sure "set it low and let it swing"...

Very good point, who can listen to such extreme stations and hear everything clearly? I like my SDR for bench testing, having an SDR makes it easy to avoid the diode detector in CB's. Having one setup full time just to listen to Hi-Fi stations isn't high on my list of priorities, though...
