A few years ago, when I had just passed my General test, the solar cycle was still up to where I could hear 10 meter repeaters all over the east coast. I used to chat with the owner of a 10-meter repeater on the island of Puerto Rico often. The sound of those repeaters were just magic to me. Earlier today there was a brief 10-meter opening. I rushed up the band to see if I could hear any of those repeaters. I was greeted by only one which was way down in the noise. Maybe one day soon they will all be back.
