[Elecraft] K3 DSP - does it use I/Q processing?

[G3XDY]

I may have missed one of the posts or FAQs, if so someone will no doubt put 
me right.

Does the K3 use I/Q processing for the final IF so that the image 30kHz away 
from the wanted signal is suppressed?

I have a high power 23cm beacon on my doorstep at 100dB above noise in 
2.4kHz, and would like to use the K3 as a high performance IF rig for 
distant beacon monitoring, hence my interest. The roofing filter alone may 
not offer enough protection when listening 30kHz away.
