>Hi all,

>ZL6QH will carry out LF beacon transmission during ZL hours of darkness on
>Friday 27, Saturday 28 and Sunday 29 December.  The same format as previous
>beacon tests will be used, with 120 second dot length, 0.42 Hz FSK, with
>transmission code repeated QQQQQ.... with each Q coded as [hi hi lo hi off]
>:
>
>hi = 137.7890 kHz
>lo = 137.7886 kHz
>
>Timing will be such that the start of a Q coincides with the hour.  It 
>takes
>10 minutes per Q, so there are six Qs per hour.
>
>The DDS exciter has a frequency shift of 0.42 Hz, and the tones should be
>within 0.1 Hz of the declared frequencies.  If the SSB backup exciter needs
>to be called upon, the frequency shift would be 0.4 Hz.
>
>The ZL hours of darkness in late December are nominally 0750 UTC (sunset)
>till 1655 UTC (sunrise).  The beacon will be transmitting from before 
>sunset
>till after sunrise, and close down during daytime.  The only planned
>exception from continuous beacon format overnight is for a 30 minute time
>slot to try for a two-way LF SSB QSO with AX2TAR in VK7, between 1500 and
>1530 UTC on Saturday.
