[Elecraft] K2 in SSB - still unbeatable in its price category

[Siu Johnny]

The current KSB2 from Elecraft has already been modified with less ripple 
in the pass band.  My KSB2 is an earlier model and has been modified to 
2.4khz based on a kit supplied from Elecraft. Under the spectrogram, I 
notice that the latest configuration gives a fairy flat response across 
pass band.

I feel the trick of getting good audio is to tune your filter by using the 
spectrogram.  K2 is still a very good rig in SSB though there is a lack of 
IF shift.  However, you need to experiment with different microphones to 
get better audio. With limitations in design, size, K2 in SSB is still 
unbeatable in its price category.  My remarks are limited to RX performance 
in the survival under strong QRM situation like the CQ WW SSB contest.

Clearly, you will miss the functions like manual notch within AGC, IF shift 
etc etc.  K2 is still a very capable rig in SSB mode.  If you install the 
KDSP2, you will need to experiment the change in Denoiser settings to 
lessen the artifacts.

cheers,
