Specifies the highest deviation that the transmit channel is permitted to have.
The available options correspond to the following channel spacings:
Option
2500 Hz Narrow Band
4000 Hz Mid Band
5000 Hz Wide Band
Specifies the deviation that
frequency. Options are specified both absolutely in Herz and relatively as a
percentage of the selected Max Tx deviation. Gain will be applied to the
CTCSS signalling to cause the deviation specified. If you subsequently alter the
Max Tx deviation, the Herz value of the subaudible deviation will alter, but not
its percentage.
Specifies the gain in dB that will be applied to received audio that is fed into
the transmitter. See "Repeater Options" on page
Specifies whether automatic gain control is applied to received audio. AGC
provides enhanced high signal handling capabilities and receiver
intermodulation protection. When signal levels are high, however, the
minimum sensitivity may be degraded.
AGC is normally enabled, but Tait recommends disabling it when:
The anticipated receive signal strength is < -107 dBm (1 microvolt) and
strong interfering signals (> -30 dBm (7000 microvolts)) are anticipated at
the receiver input.
TIA/EIA or AS-4295 RF performance testing is being carried out.
Transmitter Power Output
In the Add or Edit Channel Profile dialog, General tab, the Transmitter
power output area specifies the output power of the transmitter.
The output power is specified separately for mains-powered and for battery-
powered transmissions. The boxes alongside display the equivalent power in
dBm.
If you specify 100 W and the PA is rated at 50 W, it will run at 50 W. There
is therefore no need to alter this value if you temporarily substitute an amplifier
with lower power, for example, if there is a fault and you don't have a fully
powered module on hand.
