[Amps] Pre-Distortion Linearizer

[Colin Lamb]

"Transceiver and amplifier manufacturers will continue to give us poor
IMD for exactly as long as the major equipment reviewers (ARRL, RSGB and
DARC... but mainly ARRL) continue to remain silent."

But, these equipment reviewers are not entirely controlled by the advertisers.  They are also controlled by subscribers, and there has been no significant demand by them.  A manufacturer could produce a superior product and then promote those qualities.  The problem is that to do so would admit that their lower priced models were inferior, and they are not willing to do that.  Someone could sponsor distortion measuring events just as the frequency measuring events we had for years.  

At this point, there is only a handful of people "demanding" cleaner signals.  Some contest stations actually want dirty signals to give them greater "clear-channel" bandwidth.  

And, even if the magazines "raised the bar", that would not necessarily improved things.  The breakthrough may be when one manufacturer begins marketing their low end transceiver with a -35 db IMD rather than a -25 db one.  That would give a distinct marketing advantage.
