[Elecraft] RX Test (long)

[Larry - K2GN]

Noise or no noise vs opertional ability to hear.
For me the K3 and it's DSP, NR and NB has help me over come the hearing 
problem of being old and with teninous. The tone in my ears is so bad that I 
could NOT pass the CW requirement test for an extra class license. My 
previous radios with all the filter and DSP did not help.
The tone in my head is verified at 1150Hz. It made coping a signal that was 
in normal noise very difficult. It resonanted with my internal tone at about 
15WPM.
I've used one or the other CW encoding programs for years.
I now find that with the K3 CW is getting easier to copy.
I'm looking forward to the Rev D and expect further improvement.
Maybe I'll be able to get rid of the encodeds soon
