    Notes:
    (1) Fair conditions after hot day. Eventually clouds arrived and then
        heavy mist after which I could barely see the near full moon.
    
    (2) First satellite-Lacrosse 2 - tracked with sun at -12 deg elevation
        so sky very bright.
    
    (3) Does anyone know the story about the time signal on 10 Mhz which is
        about 4 Khz higher in frequency than WWV/WWVH ? I have recently
        noticed that either my precison crystal clock ( vintage mid 1980's?)
        was jumping about 0.5 sec or the radio time signal was jumping.Last
        night I positively confirmed that it was the radio time signal
        jumping. This time signal is not continuous and seems to go off the
        air for up to about 5 minutes at a time even when the signal was
        quite strong. I have a vague recollection that a Russian time signal
        with the callsign "R something something" used to operate around here.
        Is it perhaps still transmitting but not being maintained as it is
        most unusual for a time standards station to have time jumps- it seems
        to occur on the hour and thence every 15 minutes ?
    
    Cheers
    Greg
