I rarely venture into the LW bands but the dog had me up at 0930 UTC (11-8-13), so since the Mr. Winter is starting to creep in, I did the Radio Limbo and found a few:
198 KHz DIW - Dixon, NC
216 KHz CLB - Wilmington, NC
245 KHz ALP - Elmira, NY
250 KHz UL - Montreal, Quebec
260 KHz PYA - Penn Yan, NY
272 KHz YQA - Muscoca, Ontario
These sigs came to the R8 only through the dipole cut for 6900 KHz. Nothing special, I know, but it sure made getting up at that hour worthwhile!
