yeah sounds legit, I'm going to take a stab at this weekend, with adjusting L8. The white noise on SSB on my 2995 DX is terrible sounding. Wish I could get it to sound more like my Cobra 2000.
Some folks put a 100uf capacitor in parallel with the speaker. You should probably use a non-polarized type, but one fella swears a normal electrolytic with the polarity marked on it works fine.
Will definitely cut the higher audio frequencies.

ok 100 uf electrolytic I have a bunch of those but what voltage rating is the best for that cap across the speaker?
ok buddy, thanks so much for your time. going to tackle this in a little while, also going to put in a on/off switch for the rear amp and also tune that L8 for a little better recieve. 73
Please do let us know how you make out ! So often, people ask questions here on WWDX, get answers from folks, and then we never ever hear from them again and are left wondering whether our helpful advice, er, helped !
ok did a little work on the 2995 DX. In the photo you can clearly see the black wire going to the positive terminal on the speaker. Don't know why the wires are reversed. Put a 100uf 16v cap across the terminals and it did help some. It's just temporary right now. Might try and go with a 150uf tomorrow. Also messed around a little with L8, really didn't do anything but loose my recieve when turned. Pretty much the same with L11 and L12 not really anything help to get rid of the white noise. All 3 receiver adjustments go with the white noise. Guess I'm stuck with this crappy receiver on this 2995

I had to adjust L8 on my 2995dx because the noise interference was bad. L8 makes a huge difference in the noise it receives. Just mark it before you start to turn it. I had to turn mine down counter clockwise to get it to work. I am totally now satisfied. I did the speaker mod years ago and all it does is change the tone of the speaker noise.
Adding the hi-cut filter to this chassis is almost a must and especially when operating ssb. It's a simple jumper or in my case I've added a 3 position switch to have a low and high. It's a pretty simple mod that's completely worth it.
I did the hi cut on the circuit board also. But I still like the L8 adjustment best.
You would think so, but not in practice. This is a routine mod for truck driver radios that have acoustic feedback howl from the talkback. Doesn't seem to result in audio-chip failures that we see.
