[time-nuts] ES100 suddenly more sensitive in summer!

[Taka Kamiya]

Paul,
I live in Central Florida, which is pretty much the furthest point WWVB in Colorado is expected to serve.  My house is all LED.  Street lights in my area are about 50% LED.  Amazingly, my Casio watch still syncs up.  Using measuring receiver, I was also able to hear what must be the WWVB signal.  I forgot where you were, but you may be pleasantly surprised.  I am disappointment with La Crosse branded "atomic" clock though.

I'm stuck in a wormhole....  Hello, worms!

I plan to listen for the Swedish station SAQ on Sunday at 17.2KHz. So
testing the equipment.
What I am seeing is that LED lighting in general is covering the low
spectrum with lots of noise. In fact in our town they just replaced every
street light with a bright harsh white LED Fixture.
So as a theory I wonder if what we expect at night, isn't true anymore
since the street lights are on all night.
I have not taken a listen yet to wwvb. But fear it will be some bad news.
