Hearing now 2141 as digital then Spanish numbers. RS=3-8 using 66' halfwave for 40 meters in Sacramento, California where is is officially near as hot as the inside of a nova today.
QSB significant 3-7 second period.
I ran across it about 20 minutes ago while bandscannng and remembered HF Underground, and after resetting long-unused and forgotten password, logged in to see what it might be.
Sounds like it's HM-01, which I presume is Cuban.
