Receive and Transmission Operation

The VHF transmitter provides operation in two modes:
-

Receive Mode

-
Transmission Mode
3.4.1 Receive Mode
If /PTT input is inactive and PTT key is not pressed, the transceiver
stays in Receive Mode.
In Receive Mode the headphone output, if enabled, can provide a mixed
signal consisting of:
- received signal from antenna,
- intercom signal from intercom circuit (if intercom is active),
- signal from auxiliary input (if enabled).
In Receive Mode the speaker output, if enabled, can provide a mixed
signal consisting of:
- received signal from antenna on operating frequency,
- signal from auxiliary input (if enabled).
The signal from the auxiliary input can be automatically muted under
specific conditions.
Refer to chapter 3.10 for details.
3.4.2

Transmission Operation

If /PTT input is active (PTT key is pressed) the transceiver switches
into Transmission Mode. Microphone(s) signals can modulate the
transmitter.
The "TX" symbol in the left upper corner of the display indicates the
AR6201-(X0X) is in Transmission Mode.
In Transmission Mode, the most user actions (changing Frequency
Selection Mode, Channel Spacing Mode etc.), normally allowed in Receive
Mode, are blocked. As an exception, in Standard Mode the "Preset"
Frequency may still be changeable, even during transmission.
No intercom operation is possible in Transmission Mode.
