One ran QRSS60, the other WOLF. I think we did the tests for about a week, and found similar results. Neither had a clear advantage over that period. The conclusion was that the effectiveness of WOLF was about the same as QRSS60. While our QSO of yesterday did not fully exercise WOLF's capability, do realize that we were receiving 15 characters in a 20 minute period. QRSS60 can't do that! As originally conceived by Stewart Nelson, the "reference channel" could be used to exchange signal report information. Neither that nor real-time decoding has been realized, however. It does remain an interesting mode, with a number of limitations as listed in Alan Melia's message of this morning. For U.S. Lowfers, bandwidth is not an issue, and the potential for anything but very local interference is limited. I do believe that gps-locked slower BPSK has more potential at LF, and am slowly working on getting set up for that. Underline the word "slowly," though! John Andrews, W1TAG
