Galaxy DX959 "swing" help

[rabbiporkchop]

There is one reason and one reason only on God's green earth to reduce your carrier and enhance the radio's 'swing' on AM transmit.

An amplifier.

All linear amplifiers tend to exaggerate the carrier and diminish the peak power. Modding the radio to bring the carrier down so the amplifier isn't straining is half what's needed. Preserving the radios full peak modulated power when the carrier is reduced serves to counteract the amplifier's tendency to suppress those peaks.

Set up right, the radio should sound as good amplified as it does barefoot.

But for a radio you will use barefoot? Waste of time.

If the waveform is altered through the amplifier that means it's a nonlinear amplifier. Saying that all amplifiers are non-linear is patently untrue.

True but I have yet to find a cb amp that is linear without some work.

Chris Smit makes a nice AB biased amp with thermal tracking. I knew someone that has one and it required no work.

He's good people. One of the few amp builders I will recommend.

The purpose is for a linear. I do appreciate your input NOMAD. Hoping to come see you soon!

Does he have a website? I know somebody that's looking for one of his amps.

There's not a website to buy his amps. Is he still on Facebook? I'd contact him there. I'm not sure if the email I have is personal or business.
