[Elecraft] K3 to IC-7800 Comparison?

[Walter Underwood]

A couple of operators have posted comparisons between the IC-7800 and K3 recently. Look at these e-mails.

I've gathered ARRL Lab test data for a selected bunch of modern rigs and published it in a form making it easier to compare the rigs as TRANSMITTERS.  My report is at http://k9yc.com/TXNoise.pdf

The new synth board reduces both TX and RX phase noise quite a bit (I've heard numbers in the range of 10 dB).
