Re: [Elecraft] K3--Too much ALC creates energy on opposite sideband?

So very true.  I'm about as far removed from being an AM/audiophile type of ham as you could imagine, but I've heard guys getting "great audio" reports when they sounded like trash with lots of clipping. It's really sad, and I tend to err on the conservative side because I'd rather give up a

Re: [Elecraft] K3--Too much ALC creates energy on opposite sideband?

I find a lot of the opposite sideband splatter is originated from mis-tuned amplifiers or amplifiers which are driven too hard.   If it isn't "linear" it is a splatter generator.    And linear means just that, linear.  For an amp to be linear, it must amplify all signal levels the same amount. 

Re: [Elecraft] K3--Too much ALC creates energy on opposite sideband?

We've made great technical strides in receivers.    Transmitters, well they are best described still as "out house" technology. Nothing has changed of significance in 25+ years.  In looking at my P3 and SSB signals on the bands, there are lots and lots of really bad signals.   Yet I  most often

Hi Fred (Skip) Sadly, many of those are splattering so wide that you can hear them on the opposite sideband. Unfortunately, a report of great audio does not mean great IMD performance. Don't take this the wrong way, I am not saying you have bad IMD it just that you can't relate the 2 has being

Wes, You make a very good point. The unwanted sideband will not be 0; there will be some "residue" that can be heard if the signal is strong enough. And, a lot has to do with the measurement method at the receiver. Years ago, I was running DSBSC using a Globe DSB-100. I was told that

Although the manual doesn't say so, according to an ARRL review, the K3S is specified to have undesired sideband suppression of >50 dB.  ARRL claims an optimistic >70 dB. So if you are extremely strong at the other guy's place, he might easily hear an opposite sideband, even though your radio
