Does anyone have any idea what the ~20KHz wide digital mode QRM is at the bottom of 17m? It extends from about 18.054 to 18.076, and is a solid S9 strength here, and appears to be coming from Europe. I wasn't sure if it was local or not, but just had a cw QSO w/ an op in Spain who said it was very strong there as well. 73, Dale WA8SRA
