I'm guessing this is from the U.K. as others have mentioned. Signal is just above my local noise floor, ie: weak but copyable.
BTW, my local noise floor averages about S6 on my FT817ND using my 20 meter vertical. I tried a horizontal dipole after hours (when everyone was asleep) but it didn't lower the noise enough to make it worth the bother. Living in apartments isn't much fun for me :-(
