T6T 300 Watt VHF Transmitter Page 26 Specification
Residual FM
Both modes For a test signal of 1 kHz set at 80% modulation depth applied to the
line input of the transmitter, the unwanted peak frequency modulation
does not exceed ±500 Hz.
VOGAD
AM-Voice mode The VOGAD has an operational range of 30 dB with the threshold
level set at 10 dB below the average speech line level setting. Within
the VOGAD range the modulation depth remains at the set level
±10%. It has an attack time of less than 20 ms and a decay time of
greater than 2 seconds, both measured with a 10 dB step to 15 dB into
VOGAD.
AM-MSK mode The VOGAD is disabled.
Mute
AM-Voice mode The mute level is set at 15 dB below the average speech line level
setting. The mute can be disabled.
AM-MSK mode The mute is disabled.
Differential Group Delay
AM-MSK mode There is less than 60 µs differential group delay for signals in the
range 1200 to 2400 Hz.
Transmitter Control
Audio Inputs
Audio can be connected to the transmitter via the front panel microphone connector or via the 600 ohm
balanced line inputs. Line level setting from -30 to +10 dBm.
PTT Time Out
The time out period is adjustable from 2 to 510 seconds in 2 second steps or it can be disabled.
