I hesitated posting this morning, but after hearing this dasher again this afternoon (and into the early evening) I think it's worth seeing if others hear it too.
I was tuning around 7065 KHz and came across a dasher just above the noise - 1.5 seconds on, 5 seconds off (timing approximate). This was around 1700Z, and as the day went on the signal improved. Now at 2330z, the signal is clear, maybe an S-unit above my local noise floor.
Anyone else hearing this?
