[Elecraft] K3 deaf on 6m comparing to a FCDP+ ?

[Larry Phipps]

I'm a little late to this thread because I receive the digest version of 
the reflector, but I thought I would weigh in anyway ;-) I don't know if 
it matters that much on 6m, but the blocking IMD of the FCDP+ doesn't 
compare in any way with the K3. My tests show about 80dB before onset of 
blocking (at least on HF where I tested). That's probably about 40dB 
worse than a K3 with high quality preamp.
