Antenna adjustment for the reception of time signals
So that the CLOCK77/USB, CLOCK77/PCI or CLOCK77/ISA card can receive a time signal
to be analysed, the antenna must be properly aligned.
Please start the CLOCK77 monitor program. This program displays the arriving signals as
lines. Green lines mean that the signal is Ok, red lines, on the other hand, mean the signal is
weak, bad or disturbed. The antenna should be aligned so that only green lines are
displayed for several minutes. If no lines are displayed, then the reception of the time is not
possible.
In this case it is necessary to correct the position of the antenna. In particular
radiation-loaded computer environments disturb the perfect reception of the
time-of-day. For this reason you should position the antenna as for as possible from
disturbing computers or other disturbing devices. The time-of-day will be reset, as soon as
the time is received correctly three times. Thereby it is excluded that a false time-of-day is
appointed due to reception errors.
