NSP South Sioux City area
As of today, the NSP is still on the low-band frequencies. The Winnebago tower is the best to listen to here in South Sioux City.
I have been scanning the Fed. freqs, but still have not heard Jones Creek come live yet.

Hope that helps, but like the other posts state, check the new N-Win freqs this week, maybe they will come live. I will program them into my feed as soon as they do as well.
Safe travels!
