I calibrated my SDR and these transmissions are on 22.7 kHz. At 5:06 pm PST 2/24 was the same EAM repeated 6 times while an E-6 was out in W260 and it may have been line of sight at the time. FLDIGI was able to do 50 Hz shift and I got a pretty good copy. https://drive.google.com/file/d/0B52Hdc3cbOpxQ2lWU2FJbmRLQmM/view Paul, near Sacramento California
