1.4 Equipment Characteristics
•VHF communication transceiver with 6W output power in 2 ¼” format
•Frequency range 118,000 to 136,975 MHz
•2 microphone inputs (auto detection standard or dynamic)
•Dual-watch technology, simultaneous monitoring of two frequencies
•Auxiliary audio input
•Digital output for signaling reception
•Digital output for runway lightning
•Memory for 20 user-definable named frequencies
•Easy recall of the 10 last used frequencies
•High contrast LCD display 128x64 dot matrix
•Wide range power supply 11 –30 VDC
•Configurable energy saving mode
The FSG80 is only certified as ground radio. It has no
certification for on-board usage in an aeroplane. For this the
almost identical ATR833-II is available.
To avoid unintentional permanent transmission, the
transmitter automatically stops transmission after 35 seconds
of uninterrupted operation.

2.4 Frequency Setting

FSG80 / P/N FSG80-(xxx)-(xxx)
Operation and Installation
10 Dok.-Nr. 01.145.010.71e / Revision 1.00
1. Entering a new standby frequency to the desired value, and then
2. Interchanging the new standby frequency and the previous active
frequency by using the swap button  . .
Entering a new standby frequency can be done by
a) Manual input,
b) Recall of previously stored frequencies from the user memory
(memory locations 1-20), or
c) Recall from the list of the last 10 used frequencies.
2.4.1 Automatic Selection 8.33 / 25 kHz Channel Bandwidth
Whether a frequency is used with channel width 8.33 kHz or 25 kHz, is
automatically determined by the value of the frequency entered, and
requires no additional user activity.
The numbering scheme that is used for distinction of the two channel
widths is internationally standardized by the ICAO, and consistently used
in official documents (like e.g. VFR navigation charts) as well as in the
voice phraseology used by ATC radio communication.
Channels used with 25 kHz width are entered in multiples of 25kHz:
123.500, 123.525, 123.550, 123.575, 123.600 etc. These are compatible
with the old 25 kHz-only radios. To use the same frequencies with
8.33 kHz width, the frequency values entered are increased by 5kHz:
123.505, 123.530, 123.555, 123.580, 123.605 etc.
For more detailed information please refer to chapter 5 –but as said
above, for correct channel width selection this knowledge is not required.
2.4.2 Manual Frequency Input
The standby frequency is input by
•Selecting with the ► button which part of the frequency to change,
and
•Changing the selected part with the FREQ rotary knob.
•The swap button  interchanges the newly set standby frequency
and the former active frequency.
In order to speed up the entering of new frequencies, it is
possible to configure the radio to allow entering of those
frequencies only that are used with 25 kHz channel width.
Please refer to chapter 3.1 for information on this
configuration.

2.4.3 Recall a Frequency from the User Memory
To access the user memory frequency list, press MEM once, and select
one of the 20 memory entries with the VOL/SEL turn knob.
The selected memory entry is shown instead of the standby frequency.
In the lower row of the display, the number of the memory entry selected
is indicated by [MEM xx] (with xx = 1to 20); if a name has been provided
by the user for this memory entry, it is displayed next to the memory entry
number.

A push on the swap button  replaces the Active Frequency, a press on
the SET button the Standby Frequency with the selected list entry.
If no input is done for 10 seconds, the device returns to the standard view,
too.
2.4.4 Recall a Frequency from the List of the 10 Last Used
The radio automatically keeps track of the last 10 used active frequencies.
To access this list, press MEM twice, and select one of the 10 list entries
with the VOL/SEL turn knob. The selected memory entry substitutes the
former standby frequency.
The number of the selected list entry is given in the display’s lower row.

2.4.5 Storage of a Frequency into the User Memory
The active frequency can be stored into any entry of the user memory.
This is achieved by a long press of 1,5 seconds on MEM. The previous
memory entry will be be overwritten.
The following example stores the frequency 124.350 MHz of KONSTANZ
(EDTZ) into the user memory 7:
List entry “1“ contains the last standby frequency from the

The return to the default display (VOL) is carried out by a short press on
the Dualwatch button DW or happens automatically after 10 seconds of
inactivity.
The chosen setting can be adjusted by the VOL/SEL rotary knob.
2.5.1 VOL –Volume
Turning the VOL/SEL knob adjusts the volume of received radio signals.
The higher the value, the louder the reception of radio signals.

2.5.2 SQL –Squelch (noise barrier)
By shortly pressing the SET key once, with the help of the rotary knob the
squelch level can be adjusted.
This is a threshold that has to be exceeded by radio signal levels from
other transmitters, in order to activate the reception circuitry. The higher
the number, the stronger the radio signals have to be in order to be
received.
The VOL setting controls the volume of received radio
signals only, not the volume of the external audio input –
these are set separately with EXT.

The settingfor the squelch depends ondifferent factors, like environmental
noise. A lower number means higher input sensitivity.
This allows reception of weaker signals (radio stations at higher distance),
but can also result in pickup of radio interference sources (power supplies,
engine, strobe lights).
2.5.3 ST1 –Volume Sidetone Headset 1
The sidetone is a self-hearing or back-hearing function during
transmission. The audio signal picked up by the microphone is fed directly
to the headset,which is normally perceived as pleasant.In this menu point
the volume of the sidetone for the headset at connection 1 can be
adjusted.
