8 Placing a PTT Call
To ensure an optimal transmission, hold the Microphone in a vertical position at
one to two inches (2.5 to 5.0 cm) away from the mouth. Noisy environments may
require a closer distance or lifting up your voice.
In order to compensate network latency times, leave a short pause after pressing
the [PTT]-key but before beginning your actual voice communication. After your
communication and before releasing the [PTT]-key, do the very same again. In
order to allow other stations to join a conversation, also do not start your
transmission immediately after the other station did release its PTT.
8.1 High / Low power
In Standby Mode, if needed, when the ‘ ’ icon, ‘PTT’ or ‘CTRL’ is shown left to the
current VFO to be set, change radio output power by one of the following two
ways:
1. Press the preset [High/Low Power option]-key to switch between high and low
power. The ‘red’ indicator at the bottom of the screen of the current VFO will
change according to the set power level.
2. Access ‘MENU → Parameters → Power’ through the menu to set the output
power level of the radio. After setting, the ‘red’ indicator at the bottom of the
screen of the current VFO will change according to the set power level.
Notes: High power allows further communication distances. Low power allows closer
communication distances. If you use your radio with a hotspot, set it to low
power. For more details, please check also chapter 13.9 High / Low power on
page 177.
8.2 Select the transmitting VFO
In Standby Mode, long press the [B/E] , the Volume knob corresponding to
the VFO or [A/B]-key to switch between VFO A and B for the desired
transmission, and the current transmitting VFO will have the ‘ ’ icon, ‘PTT’ or
‘CTRL’ is shown left to the current VFO.
8.3 Receive and answer to a digital radio call
Private calls, Group calls, and All calls can be made to the preset contacts on the
current digital channel (All call rights need to be allowed by the Radioddity CPS),
and the methods for initiating and receiving all types of calls are the same. Each
digital channel can be preset using the Radioddity CPS with a ‘transmission
contact’ for Private Call, Group Call or All Call contact. Analog Calls do not require
a Contact or RX-Group.
