Allow at least 20 seconds between turning the key click on and off.
Split Mode
The PAC24 has a flexible split mode, which allows one pilot to use one
transceiver while the other can communicate on another. There are dif-
ferences in the Split Mode in a single, or a dual audio panel installation.
Note:
Due to the nature of VHF communications signals, and
the size constraints in general aviation aircraft, it is
probable that there will be some bleed-over in the Split
mode, particularly on adjacent frequencies.
PS Engineering makes no warranty about the suitability
of Split Mode in all aircraft conditions.
Split Mode, Single panel
The split mode can be activated at any time by pressing the desired
combination of XMT buttons. For instance, to activate a Com 1/Com 2
split, press and hold the Com 1 button, and then press the Com 2 button
while holding the Com 1 button. This places the pilot on Com 1 and the
Copilot on Com 2.
Split mode for Com 5, in normal (not TEL/Duplex) is possible.
Pilot on Com 2, with copilot on Com 3, Com 4 or Com 5, is also possi-
ble.
Note: Split Mode does not turn off other (Nav, ADF, etc.) selected audio to pilot.
Copilot does not hear other selected radios. Passengers will hear the pilot’s audio se-
lection
Split Mode, Dual Panel
In a dual panel installation, both pilots have access to any combination
of transceivers. Because there is cross communication, each PAC24
knows the other unit’s transmitter selection. The audio panel designated
as “Pilot’s” will have transmission priority over the panel designated as
copilot’s, when both panels are keyed for transmit on the same radio.
It is not necessary to activate the split mode by holding the buttons in a
dual installation.
