Of course, you won't get any WSPR decodes when you move out of the WSPR band, but you can use the WSPR program to see the NCDXF beacons. WSPR's panoramic display and clock synchronization make for a nice display of these beacon signals. Here's an example of a WSPR screen when I made the switch from the 10m WSPR band to the NCDXF beacon frequency at 28.200 MHz. I changed the receive frequency of my SoftRock Ensemble II independent of WSPR 2.11 by means of "usbsoftrock" running under Ubuntu. Info on the NCDXF beacons can be found at:
