[Elecraft] Elecraft K4 Vs. Flex 6400

[Pete Smith N4ZR]

Interesting question. The Flex 6700 is close to the top of the list with 
some sort of updated hardware, while the 6400 is below the original K3, 
and far below the K3 with the new synthesizer(s).  The difference 
between the 6700 and  the K3 with new synth is only 1 dB in terms of 
narrow spaced dynamic range.  Another data-point in favor of holding on 
to my K3.

73, Pete N4ZR
