Ken,
Look at

you will see the white door illuminated by a high pressure sodium light.

What color are grow-lights?
The reason I ask is that last night, late, about 4:00 AM, I happened to look
out our upstairs window as I headed to the bathroom, and noticed very
bright, pinkish light emanating from a neighbor's window.
It is on 24/7.
I then listened to two recordings I got from the ARRL's site, and both sound
very similar to what I am hearing on 80 meters, although not quite.
Anyone?
