I just had a look at the K2 block diagram in the K2 Power Point set in
preparation for a local presentation of the K2 in Oslo. In the block
diagram there seems to be an IF output, although it is no longer in the
block diagram on the web site 
(http://www.elecraft.com/manual/Appendix_C_blk.PDF ). The output was
shown right after the noise blanker and before the T/R switch and
crystal filter

It would be interesting to hear if there was previously a plan to bring
the IF out. It could be used for a PC-based spectrum display, FM
demodulation etc.
