Full Duplex: When unchecked, transmitting on this radio will mute the receive
audio. When checked, receive will not be muted. Use for satphones or other full-
duplex devices or radios where the user must hear setup tones before speaking,
or to hear transmit sidetone from the radio.
Mute All RX on TX: When checked, transmitting on this radio will mute receive
from ALL radios that also have “Mute All RX on TX” checked. Use in situations
where radios have RF interference with each other that cannot be solved by other
means.
Sidetone Generator: When checked, the P139-HD will provide transmit sidetone
for this radio. Use with “Full Duplex” unchecked to silence any interference from
the radio.
When a setting is changed, the web page updates the hardware with the new
setting. While this is happening, the website will prevent further changes (Figure
7).
