The picture on the right shows the starting
screen that is briefly displayed when entering
the ETM memory for SW. In this example,
“E20” indicates that the current listening time
is between 20:00 and 20:59, whereas “ “ indicates that the last time an
ETM scan was done during this time-range the device found 136 broadcasting
frequencies.
Tips:
Time-specific ETM memories are based on the clock time of the radio.
Before initiating an ETM scan, make sure to set the time accurately.
If no previous ETM scan has been done for a specific time-range, the ETM
memory will not show any stations. For
example, the figure on the right indicates
that no ETM scan has been performed during
the 9:00-9:59 hour time-range.
For LW/MW: the internal ferrite antenna is directional, you may need to
adjust the position of the device to improve ETM results. Due to the nature
of radio wave propagation, longwave and medium wave reception is
generally better at night than during the day.
For SW: radio signal propagation depends on the condition of the
ionosphere, which itself is affected by a variety of factors (time of day,
season of the year, sunspot cycles, etc.).
For better ETM results, try to adjust the length of the whip antenna for FM
and SW reception, or rotate the radio for better reception of MW and LW.
Alternatively, try to find a different location within the building and preferably
near a window.
Electromagnetic interference (EMI) from household appliances, as well as
the location within a building, affects ETM results.
