[Elecraft] Enhancements and improvements to the K3S

[Phil Wheeler]

Bob,

Good idea to change the thread title!

What in this list will improve TX audio -- other 
than the KSYN3A (which I already have in my K3)?  
Speaker audio improved, yes, but that seems to be 
RX only.

FWIW -- I think the K3 is already a "great" radio, 
but agree that the K3S will be still greater. But 
for me, if I had to choose only one item on the 
list below, it would be the KSYN3A -- and I've 
already chosen to add it to my lowly K3 :-)

Of the other items below, I've already added the 
coverage of 630 m and below, and will likely add 
the new DSP board with its RX audio improvements 
when it comes available.

73, Phil W7OX
