As you can see in the photos this is a 4 transistor but I couldn’t find any adjustable capacitor in it either. I don’t know enough to properly adjust one anyway. lol I’ve been reading about negative feedback after Nomadradios reply but it’s way over my head. Is it possible to add a negative...

If there is any way to solve the issues I’m willing to give it a try. I just don’t have the knowledge to know where to even begin. I’m decent with soldering but my experience with electronic circuitry is very limited. Any help would be greatly appreciated.

Here are some photos of the amp.

Thank you! I’m pretty new to all this but I’m learning thanks to the help of people like you. I will take the cover off and post some photos.

It’s high just with dk and I don’t see any change with modulation. I put a new Kenwood low pass filter inline both before and after the amp and it didn’t help.

Thank you for helping clear that up for me! I will let everyone know how it goes after I get the low pass filter I just ordered.

Thank you! I haven’t opened up the radio to turn down the wattage yet but I will be soon. I’m still going to put a low pass filter in line even if lowering the dk helps.

That is what I was thinking from the research I’ve done on these types of amps. My question is, do I want a band pass filter or a low pass filter? ICE makes both kinds of filters for 11 meters and they have a cut off of anything above 30 MHz. Any input will be greatly appreciated! Link to ICE...

That mostly makes sense to me. I didn’t think 3.5 watts would be too high a drive for the amp but that may be it. I think I can figure out how to turn the 142 down to whatever it may need to be to make a difference. I am confused about putting a filter between the radio and amp though. I thought...

I’ve used 3 different meters. I don’t have a Bird, just a Dosey and 2 older meters but they all read very close to the same. The meter is between the amp and antenna.

As far as I know this amp isn’t “tunable”. It appears to be patterned after a Palomar Elite 250. I forgot to mention I’m using RG8U coax throughout.

I tested all jumpers as well as tried various lengths. From my understanding of the research I’ve done, coax length doesn’t really do anything but fool the meter into thinking the swr is good. I tried it anyway with no changes.

I’m having high swr issues when I put amp inline and power is on. I’m just getting back into cb radio after many years so I’m far from an expert. I have learned just enough to probably be dangerous. lol I’ve read through numerous threads here and I’m thinking it’s a harmonics issue. The amp is...

Is this amp still running well? Any problems with harmonics messing with swr? You definitely got it at a great price! They seem pretty hard to find at all in the U. S. now. I’ve seen a couple on eBay that are running around $400 used with shipping. I guess that makes it hold pretty true to...

Great information. Thank you!
