Just to add a little info, I measured and compared my KX3-SN475 to my
K3-SN4043:
http://www.kl7uw.com/HF.htm Half-way down the page.
KX3 on 6m with preamp on was -127 dBm with 2.8-KHz SSB*
K3 on 6m with ARR Gasfet preamp was -137 dBm*
on 10m the K3+PRE outperformed the KX3, as well
Subsequent to this testing I acquired a PR6-10. I helps the K3
tremendously but not quite as much as using the ARR preamp**.
Subjective impression is the PR6-10 equals the KX3 in MDS.
*Add 7.5 dB for MDS at 500-KHz bw
** Uses mgf-1302 GasFet with 0.5 dBNF and 25 dBG
I don't own a KX2
