Re: Elecraft] Does the K3S DSP support LMS noise reduction ?

What is LMS Noise Reduction? I retired when my brain became filled to capacity with acronyms. Any new ones just overflow to the drain. :-)

Re: Elecraft] Does the K3S DSP support LMS noise reduction ?

The simple explanation: LSM stands for "Least Mean Square". It's a
mathematical algorithm used in digital signal processing to implement a
specific type of filter. If you really want the gory details, see here:

https://en.wikipedia.org/wiki/Least_mean_squares_filter

Of course, this doesn't explain how one would select that algorithm within
the K3, as I found no such indication in either the DSP or IF noise blanker
selections. Maybe it's unique to the K3S? Dunno.

Re: Elecraft] Does the K3S DSP support LMS noise reduction ?

For those that choose to use acronyms in their writing or communication,
it is usually deemed proper to identify the details or translation at
the first use of the acronym in any piece. The acronym will then be
most likely understood during the reading of the remainder of the piece.

After all........we are supposed to be "communicators" aren't we? Just
sayin'.

Bob,

You must not listen to 20 SSB much if you consider
hams to be fine communicators :-)

As for LMS, a local suggested Limited Mental
Stability, but I think that has to be op-provided,
not by any rig!

Bob,

Sure didn't mean 40m in vk?

Here you will hear such classic gem's like Rodgy, 10-4, swar, loud n proud....should I go on?

I better not....it's a hoot, but, it does grow old rather quickly.
