Use the K3 utility to save the config from the "Good" K3, then use the same utility to save the config from the "suspect" K3. Finally use the K3 Utility to restore the config from the "good" K3 into the "suspect" K3 and retest.
If that doesn't fix the issue then I'd start double checking the connections per the assembly manual.

Gents, in spring I made an upgrade to my K3 (#59xx) with the internal ATU KAT3A. After this I guessed that there is a noise drop on all bands from 160 up to 10, but was not 100% sure. The strange thing: neighbor stations with similar setup always gave much better reports than me, at least 10 dB better. I was struggling a lot with my antennas, checked coax every now and than etc. but everything was o.k. At that time my main RX became suspicious. Last week I bought a K3/10W (#39++) from a local ham as a backup here in my shack. Comparing both rigs shows a huge difference in sensitivity. Very weak signals, almost in the noise on 10 Meters are clearly audible in the freshly bought K3 while there's almost nil on my old one. So i fired up my HP8664A signal generator today and found my old K3 to be at least 9dB worst compared to new one. This is for the main RX in my old K3 while the second RX iny my old K3 is almost similar to the new K3 when fed through the AUX input (not through ANT 1!!). So whats going on here? Something broken in my old K3 when I made the upgrade with KAT3A? Wrong wired? I have no idea, perhaps you got one?
