Another Northern California listener here on the SF Peninsula. I also copied AZ by ear, local afternoon ~1500 PST (+DST), over the course of about 1 hour.

I was pleased to hear this signal, as it had not made it here for quite some time.

Nice report Exo. Over the weekend, I was able to copy AZ, and also a number of the beacons clustered around 13,555.xxx. The slower mode signals visualise nicely using Spectrum Lab in QRSS3 mode. I have a screenshot, but need to work out how to include it in a post...
