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.

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?

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

    Sorry to hear you troubles, he is famous around here for his scams.

    My first thought was the i.r.s. may be interested in a long term money making scam without proper taxes being paid..probably more than electronics involved.
  • @ Toll_Free:
    My first thought was why hasn't someone paid him a visit. I mean, his address is posted above.
  • @ beakster1715:
    Good news! I opened an appeal case after eBay sided with superhawkwss6. I also opened an IC3 case & sent that information to eBay. Within an hour they responded, reversed their decision and returned all of my money. Unfortunately, superhawkwss6 stole my CB radio and eBay will likely not suspend or close his account, but rather allow him to continue his criminal activity. I think I'll still file a report with our sheriff's dept (the sheriff is a friend of mine) though I know this type of crime isn't worth their time. This guy needs to be stopped and I'm certainly going to do my best to make that happen.
