[Elecraft] K3 Keying and NR No Effect Here

[Chris Page]

Thanks Stewart.

I loaded the latest firmware this morning (I was using 2.20) but 
before I did that, I tried monitoring my transmitted signal on 
another receiver, on the same 80m frequency that I did the test with 
my UK friend yesterday morning.  I cannot tell any difference to the 
keying between having the NR switched in and switched out.

After loading 2.23, my signal sounded exactly the same on my other  
receiver and a report from a European station on 20m said the keying 
was "perfect" and there was no sign of any clicks.

I now intend leaving well alone and am putting the experience down to 
one of the mysteries of life!
