Primarily because the books I've read on noise reduction tend to emphasize autocorrelation as the technique with the main variations being the selection of the time delay and judging the results to a

That's a feature, not a fault, so it can't be cured. Lets you audibly match the sidetone pitch with the received signal to be zero beat when you respond to save on band usage (and in a thickly piled

But an FIR or IIR filter can't compare coherent signal to incoherent noise and enhance multiple signals while suppressing the noise between them. -- 73, Jerry, K0CQ, All content copyright Dr. Gerald

Something the ear and spectrum analyzer may show is the character of the attenuated noise. I'd expect an adaptive bandpass filter to have a considerable depth to the skirts and the noise left to be s

My point is that the residual noise from filtering will sound like the original noise but at a reduced level. The residual noise from autocorrelation doesn't sound like the noise that went in. Whethe

The fact remains that for weak signal work based on human skills, not on computer software of questionable reliability, CW is still the most effective mode. It works for VHF aurora propagation modes,

Average power may NOT be talk power. The fundamental problems come from two things: 1. the PA has a peak power limit that if you try to exceed that you get splatter. ALC works to prevent that over dr
