[Elecraft] K3 NB Info

[Ed Cole]

I'm trying to use the DSP NB on local noise to improve my 6m reception 
of very weak signals (i.e. eme signals).

There are three ranges of DSP NB T-1, T-2, and T-3 with level settings 
of 1 to 7.  The levels are self explanatory, but have found no 
description about the three ranges (application, function, etc)

I've inquired of fellow K3 owners that do eme and they say it improves 
SNR with no deterioration of digital signals (specifically JT65 or Q65). 
  FT8 is probably a good test and more widely used.

Opinions and recommendations.

My 6m local noise peaks to S7 in the NE and drops to S2 when antenna is 
rotated to SE thru West.  Elevating 13-degrees also helps, dropping S7 
to S4.

Tnx & 73, Ed - KL7UW
