I think the real issue is being missed there. The real test of non-linearity is the production of harmonic and intermodulation distortion. This means allows measurements of nonlinearity as small as a
But the issue is one of gain "expansion" not of compression. Does expansion produce the same kind of distortion that compression does? 73 Gary K4FMX _______________________________________________ Am
The real test of non-linearity is the production of harmonic and intermodulation distortion. Exactly! The Luxembourg effect!!! (although that is actually cross modulation) 73 Peter G3RZP ____________
Probably, but my guess is that the rate of change is so slow, and the increase in signal is so low that the increase in IM distortion is not noticeable. Richard L. Measures, AG6K, 805.386.3734. www.s
Would CW telegraphy signals be unreadable or simply vanish? That's what I thought until I sold the Plywood Box amplifier and made some on-the-air measurements with a step-attenuator. ________________

But how many reports of the "Luxembourg effect" over the decades have been due to cross-modulation in receivers? We skeptics need to know. -- 73 from Ian G3SEK _______________________________________
But how many reports of the "Luxembourg effect" over the decades have been due to cross-modulation in receivers? We skeptics need to know. The Luxembourg Effect was first noted in the 1930s when Radi
A similar effect was used on a daily basis at the Lohnsfeld Germany receiver site. The transmitter was at Ft. Detrick MD and they would come up along side a strong European broadcast station for the
