VA3LK received by G3XDV
28 January 2001


0353UTC: "LK". Note that the AGC in the software (Argo) puts gaps in the received signal when there is a noise burst (see the effect on the Loran line at the top).
The double trace just below the Morse is on all night and stops abruptly at about 0720UTC.


0641UTC: A 'Q' from the 'CQ'?


0723UTC: Another 'Q'.
