Table 2 Active Transceiver View Indicators
Indicator Description
RX Indicates transceiver is receiving. Only visible when receiving.
TX Indicates transceiver is transmitting. Only visible when transmitting.
M Indicates transceiver is muted. Only visible when muted.
90%
Placeholder for current volume level. Always visible. Valid values range
from 0% to 100%.
DIR
Indicates transceiver is in direct mode. Only visible when transceiver is in
direct mode. When not displayed, transceiver is in repeater mode. This
indicator should automatically appear for preset channels whose transmit
and receive frequencies are identical.
PVT
Indicates transceiver is in private mode, i.e. encryption is enabled. Only
visible when transceiver is in encrypted mode. When not displayed,
transceiver is operating in the clear.
SCAN
Indicates transceiver is in scan mode. Only visible when transceiver is in
scan mode. When not displayed, transceiver is not scanning.
SIM
Indicates transceiver is participating in a simulcast. Only visible when
simulcast mode is active and the transceiver is participating in the
simulcast. When not displayed, transceiver is not participating in a
simulcast.
RLY
Indicates transceiver is participating in a relay. Only visible when relay
mode is active and transceiver is participating in the relay. When not
displayed, transceiver is not participating in a relay.
PTX
Indicates transceiver is associated with PTT-X. Displayed in reverse video
(as shown) when transceiver is the active transceiver for its PTT group.
Can change if transceiver is participating in a simulcast, in which case the
simulcast trigger PTT will be displayed.
The Transfer-Button is a soft button that allows the operator to flip-flop the active and standby
channels. The Transfer-Button shall only be visible when the active transceiver is operating in standby
tuning mode.
The Active-Channel-Field is always visible and displays the channel to which the active transceiver is
currently tuned. When operating in Tactical-Mode the Active-Channel-Field shall display the channels
number and alphanumeric identifier if tuned to a preset channel. In SCAN mode, this field will display
the active channel. When Paused or Delaying in SCAN mode, this field will display the channel where
the pause or delay occurs. If tuned to a manual channel, the number shall be displayed as ‘..M’ and the
channel’s receive frequency shall be displayed in place of the alphanumeric identifier. If the PTT is in
effect, the alphanumeric identifier shall change to the transmit frequency of the channel, and if the
channel is being encrypted, the encryption key shall be displayed to the right of the transmit frequency.
If the channel is for receive only, the alphanumeric identifier field shall display “RX ONLY” during an
attempted PTT. When operating in ATC-Mode the Active-Channel-Field shall display the channel’s
receive frequency.
The Standby-Channel-Field is only visible in standby tuning mode, and displays the channel to which the
active transceiver will be tuned when the Transfer-Button is pressed. When operating in Tactical-Mode
the Standby-Channel-Field shall display the channels number and alphanumeric identifier if tuned to a
preset channel. If tuned to a manual channel, the number shall be displayed as ‘..M’ and the channel’s
receive frequency shall be displayed in place of the alphanumeric identifier. When operating in ATC-
Mode the Standby-Channel-Field shall display the channel’s receive frequency.
The Transceiver-Function-Menu is always visible and displays the functions available for the active
transceiver. Different types of transceivers have different functions. Only functions applicable to the
active transceiver shall be made visible. Functions that are applicable but not available shall be shown
but disabled. The following table lists the transceiver functions and their applicability.
