In response to a user request, have tested and checked in enhancements to 3.0.2.4 which add support for the feature you requested which runs the quickest wsprd on those 'noise level only' bands like WWV_10.  You can see the noise level charts produced for those bands like WWV_10 at: http://wsprdaemon.org/graphs/NorthernUtahSDR/

In your conf file schedule you can explicitly define  mode 'W0"  (that is a zero) , e.g. "00:00 KIWI1,WWV_10,W0"

But W0 is now the default mode for those bands, so "00:00 KIWI1,WWV_10" defaults to W0.

Since this mode is a pure enhancement of  the functionality of 3.0.2.4 and (I think) the NortherUtahSDR (KA7OEI-1) site is the only user of those WWV_x bands, I haven't incremented the version number.

So if you run 'git pull' on a WD directory in which 'git checkout 3.0.2' has been run, you will see several files updated.  But if you don't have one of those WWV_x bands defined in your schedule, there should be no change in the operation of your site.
