100Menu ModeFT-891 Advance Manual16-19 ANTI VOX GAINFunction: Sets the VOX anti-trip.Available Values: 0 - 100Default: 50Description: The sensitivity of the anti-trip circuit may be adjusted so that the VOX circuitdoes not accidently engage due to the sounds from the transceiver speaker.Increase the anti-trip value to the point that sounds from the transceiverspeaker do not engage the transmitter while using VOX operation.16-20 DATA VOX GAINFunction: Sets the VOX GAIN while operating VOX during the sending/receiving of data(PSK31, RTTY, etc.).Available Values: 0 - 100Default: 50Description: Set the data input VOX gain to the point that the data signal reliably engagesthe transmitter, and also releases the transmit when there is no data signal.16-21 DATA VOX DELAYFunction: Sets the VOX DELAY time while operating VOX during the sending/receivingof data (PSK31, RTTY, etc.).Available Values: 30 - 3000 (msec)Default: 100msec16-22 ANTI DVOX GAINFunction: Sets the data VOX ant-trip.Available Values: 0 - 100Default: 0Description: The sensitivity of the anti-trip circuit may be adjusted so that the VOXcircuit does not accidently engage due to the received data while operatingVOX. Increase the setting to a value that the VOX circuit does not engagedue to the received data (the higher the value the greater the operationsensitivity).16-23 EMERGENCY FREQFunction: Enables TX/RX operation on the Alaska Emergency Channel, 5167.5kHz.Available Values: ENABLE/DISABLEDefault: DISABLEDescription: When this Menu Item is set to ENABLE, the spot frequency of 5167.5 kHzwill be enabled.The Alaska Emergency Channel will be fount between the PMS memorychannel “P9U” and the memory channel “01”.Important: The use of this frequency is restricted to stations operating in or near Alaska,and only for emergency purposes (never for routine operations).See §97.401(c) of the FCC regulations.
