4.8.2 TRACKER SOP A
Tracker SOP A is a new version of the original Tracker SOP but without the
need for the SatTalk II audio controller component. The audio operations of
the SatTalk 2 are now included in the Tracker SOP “A” transceiver. This
brings the operational characteristics of the Tracker SOP “A” model to the
same as any remote mounted Comm transceiver. This unit can be operated
with or without an audio panel, and needs no external amplification of the
phone audio.
Most audio panels only support ½ duplex, or push-to-talk communications.
For obvious reasons, this is somewhat limiting for phone conversations. The
reason Full Duplex audio panels are recommended for proper operation is to
retain the full transmission capabilities of your on board communications
transceivers. In a full duplex system, Comm 3 is devoted to the Satellite
phone, while Comm 1 and 2 are the VHF Transceivers. When a call is
initiated, Comm 3 is selected and communications happen as they would on a
phone; without the need to push-to-talk. Meanwhile, the pilot is still able to
monitor his on board radios, and if necessary, key the Mic to allow
conversations on the VHF Transceiver.
In a half duplex audio panel, keying on any transceiver line will cause the
muting of all other sources of incoming audio. Safety of flight can be
compromised in this fashion by muting an incoming call from ATC while
holding down the key to communicate on the phone.
It is strongly recommended that a Full Duplex audio panel such as the PS
Engineering PMA7000B or NAT AMS50 be used when interfacing the SatTalk
II (or the SOP Model “A”) as a transceiver.
4.8.3 SOP DIALER
With both SOP Dialer panels it is recommended that if you do not have a
dimmer circuit that maintains voltage with the dimmer off, that you connect
the lights to a two stage dimmer circuit.
4.8.3.1 SIX POSITION
The six position dialer has been dis continued. Refer to older install manuals
for information on this unit.
