Experimental Station WL2XUP is transmitting WSPR on 40.662 MHz in the 8-meter band.

WL2XUP is an FCC Part 5 Experimental station operated by Lin Holcomb, NI4Y, in Georgia. It’s licensed to operate with up to 400 W effective radiated power (ERP) between 40.660 MHz to 40.700 MHz.

A 2019 Petition for Rulemaking (RM-11843) asked the FCC to create a new 8-meter amateur radio allocation on a secondary basis. The Petition suggests the new band could be centered on an industrial-scientific-medical (ISM) segment somewhere between 40.51 and 40.70 MHz. The spectrum between 40 and 41 MHz is currently allocated to the federal government and, as such, within the purview of the National Telecommunications and Information Administration (NTIA).

ARRL member Michelle Bradley, KU3N, of Maryland, filed the petition on behalf of REC Networks, which she founded and described in the Petition as “a leading advocate for a citizen’s access to spectrum,” including amateur radio spectrum.
