Thanks for all of the comments. I had an early experience in ham radio
with satellites, AO-10 and AO-13, at frequencies 144, 430, 1.3 Ghz and 2.4
Ghz. Because of those frequencies N-connectors became a way of life. So I
automatically think of N-connectors when I am working with those
frequencies. If Elecraft offered the directional coupler with
N-connectors, I would buy it and pay extra for the connectors.

Please note that changing the connectors from SO-239s to N's will
uncalibrate the W2's directional coupler as you go higher in frequency -
especially on 432 MHz, leading to less accurate SWR indications. It may
also affect wattmeter accuracy.
We included additional compensation components in the coupler design to
cancel the reluctance of the SO-239s, flattening the coupler's frequency
response.

Yes Paul, the connectors on the sending units are easily changed.
All mine have been changed using kits from Morse Express that
come with nicely-done interfacing plates to compensate for the
pattern change. I've also changed the three antenna connectors
on my K3 using these neat little kits.
A caution ... take note of the TRANSMITTER and LOAD labels and
the positioning of the cover. You have a 50-50 chance of reversing
the labeling if you reverse the cover. The labeling is on the -cover-
and not the unit itself.
