Fig. 14 Input of a new COSPAS-SARSAT frequency
With hotkeys “Frequency” or “Channel” (s. Fig. 14, positions 1 and 2) the corresponding
variant of the input dialog is selected.
As a result of the 8.33 kHz grid of the AU, after selecting any channel group, the indication on
the “Bearing” page will be as follows:
▪
“406.025 MHz” for Channel ABC
▪
“406.033 MHz” for Channel DEF
▪
“406.042 MHz” for Channel GH
▪
“406.050 MHz” for Channel IJK
▪
“406.058 MHz” for Channel LMN
▪
“406.067 MHz” for Channel OPQ
▪
“406.075 MHz” for Channel RS
The corresponding Cospas-Sarsat channels for the entered Cospas-Sarsat frequency are
shown in the right lower corner of the “Standby” frequency field. It is also shown for the active
frequency.
6.1.2.6 Memory Dialog
The memory dialog (s. Fig. 5, position 5) provides a list of stored frequencies (channels),
which facilitates restoring any frequency from memory to the active bearing mode.
Selection of the frequencies works by using the “up” and “down” arrows. Recalling the marked
frequency into the active bearing mode is accomplished by pressing the button “OK”.
Furthermore, each frequency can be marked for the function “fast channel scan”, which
means that by activating this function, the marked frequencies will be used for scanning. The
fast scanning function itself is limited to a maximum of eight frequencies, so there is also a
maximum of eight frequencies which can be marked for scanning in the “memory” dialog.
