3.12.1 TRANSCEIVER FUNCTION
In both the set standby and set active commands the “a” field represents the transceiver function:
N = Normal Transceiver receives and transmits on the active.
M = Monitor Transceiver receives on both active and standby, and transmits on active.
0 = Unchanged Transceiver function setting not changed
Hence it is possible for the external equipment (if it supports these commands fully) to change the active
and standby frequencies, and switch the M760Q in and out of monitor mode.
3.12.2 TRANSCEIVER STATUS
The Comm Transceiver Status command contains the “a” field for the transceiver’s status:
R = Normal receive Normal receiver mode – monitor function inactive
M = Monitor service Monitor function active
T = Transmit enabled PTT button is down - transmitting
S = Stuck mic Transceiver transmitting for longer than 45 seconds
F = Comm failure Transceiver inoperative
IMPORTANT NOTE
After 45 seconds of transmission, the M760Q will flash the red LED
TX annunciator. During this period the transceiver status will default
to S (stuck mic).
3.13 PC INTERFACE
The M760Q Frequency Compiler software can be used to connect to a PC or laptop with a
windows operating system (XP or later version).
The user can quickly compile channel lists and write them to the M760Q. Refer to the Microair Avionics
website for full details of the M760 PC application ( www.microair.com.au
