AMATEUR RADIO STATION
If you operate the transceiver for a VoIP amateur radio
station, select "SQL" from Advanced Menus 20 and 21,
"MSQ/SSQ Output Conditions".
If you use CTCSS as well, to avoid sending noise or
unnecessary signals from the station to the Internet, select
"Unmute" from Advanced Menus 16 and 17, "Muting the
CTCSS tone".
All received audio will then sound from the speaker
regardless of the matching status of the CTCSS frequency.
The received signal is transferred from the ACC 2/USB
port only if the CTCSS frequency matches.
