[Elecraft] [K3] SN 00128 and comments on DSP version 1.45

[Richard Everitt]

I am pleased to say that K3 serial number 128 is built and working. The 
build process took a little longer than expected (10 hours) but as this 
was my first Elecraft kit I progressed slowly and surely. No major 
issues were encountered and the radio worked first time. I have a few 
photos of the build process and some comments on the radio at

The wait was long but worth it.I am most impressed by the selectivity 
and look forward to using the K3 in a contest.

I started off with DSP version 1.43 and I was very impressed by the 
Noise Reduction facility as I live in an electrically noisy suburban 
area. The NR made listening so much easier on the ears although care was 
needed as too high a NR value would result in weaker CW stations not 
being heard at all! I have now upgraded to DSP version 1.45 (plus MCU 
1.48) and the NR feature seems to not work as well. I have tried the 
higher settings (3 and 4) of all NR 4 modes in CW and the noise 
reduction doesn't seem to be working as well as before. Has anyone else 
noticed this?
