[Elecraft] K3 & K3S Options Last Time Buy Update (12/02/2022)

[David Gilbert]

Although some will no doubt disagree, I think the short answer for you 
as a casual op is "no" ... depending, of course, on just how "casual" 
you consider yourself to be.

The new synths do indeed give considerably better performance, though 
... you just might not notice them if you are a casual operator.  The 
new synths have much better performance for multiple closely-spaced CW 
signals within the audio passband (which avoids the mush created by the 
old synths), and if you have two receivers the local oscillator signals 
remain sync'd as you tune.   The phase noise is better with the new synths.

Here is a better report:

Personally, I think it was a safe bet to switch to the new synths if you 
ever plan to sell the rig.
