I see. Attention to detail does not go well with ADD.

The picture in that post, does show the correct location to install the resistor.

Thanks! I deleted the prior post to eliminate confusion with the placement.

Here's a picture of the adjustment pots. I wonder what W3 does. Anyone know?

WOW! so glad I did the resistor ALC mod mod(sic). on low power, which I set at 1w, the thing swings to 30. Not much test and verification other than a "loud and clear" radio check done yet.

That's enough forward swing to insure a good amount of negative peak cutoff. On low power I set the carrier to key 6 watts and set the AMC to peak 25 on the Bird 43P. As you can see, the radio can easily overmodulate now, if the AMC is set too high, or the carrier is set too low.

I'll keep that in mind. The idea is to see what it will do with a 2 stage amp on each stage.

Has anyone done a direct inject audio mod to this radio?

Probably not yet, but the fact it uses a series pass modulator, says you can inject outside audio by driving this stage. Results would just be limited by what you feed into it.

Just noticed a unique quirk with the volume control on this radio. When turning the volume all the way down, the number just below one, is not zero. It's 59! When you want to turn it all the way down, the normal action to do that, produces the exact opposite effect of full volume. That was like an instant two coffee adrenaline rush late last night. It also explains why the default knob setting is not for volume and why they configured the power switch as a mute button when momentarily pressed. It is the only way to turn the volume all the way down.

What about a capacitor in the DC supply line? (I have not tried to put this in a mobile yet, just got it )

I've tried that, and a choke. No love. It is a great little radio, but only for stationary use. It picks up too much noise from the vehicle.
Has anyone had any luck correcting this?

My SR84HPC Stryker now performs better than all my other radios after the real modulation modification.

Removing modulation limiters do not always distort every radio theyre removed from somtimes the removal brings a radio to life like the president ronald

Just curious as what you're calling the "real" modulation mod?
