[Elecraft] Difference between a K3 and a K3S

[Tom Azlin W7SUA]

I agree.

My sort of early K3 ( s/n 17xx) simply has received every possible 
upgrade put including the new synth board and the new I/O board. So is 
pretty close to the K3S seems to me. If I was unlucky enough to have 
purchased the last K3 I would have simply put in all the upgrades. Both 
are worthy radios. My K3 is a field day veteran on a 4A club and did 
very well with nearby K3 stations ( we did an all Elecraft FD with a K2 
and multiple K3s. With antenna gain on 40 and 20.)

73, tom w7sua
