If a Cospas-Sarsat frequency is entered, the value will be automatically converted to an input
in the 8.33 kHz grid (s
.
6.1.2.5).
The inputs will be set to the following values:
406.025000 MHz = Channels: A (
406.022 MHz
), B (
406.025 MHz
), and C (
406.028 MHz
)
406.033333 MHz = Channels:
D
(
406.031 MHz
),
E
(
406.034 MHz
) and
F
(
406.037 MHz
)
406.041666 MHz = Channels:
G
(
406.040 MHz
) and
H
(
406.043 MHz
)
406.050000 MHz = Channels:
I
(
406.046 MHz
),
J
(
406.049 MHz
) and
K
(
406.052 MHz
)
406.058333 MHz = Channels: L (
406.055 MHz
), M (
406.058 MHz
) and N (
406.061 MHz
)
406.066666 MHz = Channels: O (
406.064 MHz
), P (
406.067 MHz
) and Q (
406.070 MHz
)
406.075000 MHz = Channel:
R
(
406.073 MHz
) and
S
(
406.076 MHz
)
Corresponding Cospas-Sarsat channels for the entered Cospas-Sarsat frequency are shown
in the right lower corner of the “Standby” frequency field. They are also shown for the active
frequency.
Note
The squelch level is set to 30% by default for the first input of the “Standby” frequency.
After changing the squelch level, the new value is stored together with the corresponding
frequency (active frequency with squelch / standby frequency with squelch).
For Cospas-Sarsat frequencies the squelch is set to “Auto” by default.
For more information about squelch s. 6.5.3.
6.1.2.4 Input of Channels
Generally, channel input works the same way as frequency input: the input dialog is divided
into a section for the active channel and a section for the new channel (s. Fig. 8, fields A and
B).
With the “swap” function the “standby” channel can be set to “active” and the currently active
channel becomes “standby”.
