It's 15:20Z, and I have just finished a qso with K2UTC on 15 ssb. We had peaks of 15 over pretty consistently throughout the qso.
This may be a good day to try AM, so I'll keep an ear on 21.425. K2UTC and I talked many times on 10 meter AM during the early 70s. Mike Duke, K5XU American Council of Blind Radio Amateurs
