[Elecraft] Happy But Very Sad

[Scott Manthe]

I said the K3's transmitter was superior to the FT-5000, not perfect. 
The ARRL review lists the 3rd order TX IMD numbers at -30db for the 5000 
and -29 dB for the K3, but those numbers alone don't tell the whole 
story. Take at look at the ARRL's phase noise numbers and spectral 
display characteristics for the FT-5000's transmitted signal and compare 
them to the K3 and then get back to us. To be fair, the K3 tested does 
seem to have an issue with inferior 9th order IMD numbers, though.

These figures were without the FT-5000's processor turned on, which of 
course, dirties up the 5000's signal quite a bit, unless that "feature" 
has been fixed. If it has, many contesters will be tearing up, because 
that and the key clicks help FT5000 ops get higher scores.

Re: your other post, my K3 is rated at 100 watts output, so I'm sure 
someone running one at 120 watts will notice that the performance does 
degrade. I find the slightly higher PS voltage an intriguing idea.

The FT-5000 is a fine rig, and is fairly clean in class A mode, with the 
processor turned off, but most people don't run them that way.
