PTRL NV/3 & RXRL NV/3
9.6.1 Screen #22: Transmission frequency setting
In this screen, you may change operating frequency through two subsequent steps:
first edit the digits to the left of the comma (MHz) and then those to the right (tens and
hundreds of kHz).
9.6.2 Screen #23: Output power setting
This screen lets you set the required output power (Set), which must not exceed
maximum unit capacity or licensed power. Actual output power is shown on the right,
in the second line.
Actual power may be lower than set power when the maximum limits are reached.
Likewise, certain transmitter series have a minimum output power limit that must not
be exceeded.
9.6.3 Screen #24: BF input level setting
This screen lets you set the sensitivity of BF input channels, i.e. the multiplex, right
and left channels. Please note that multiplex signal and right channel use the same
circuits and sensitivity is set to the same value for all audio and multiplex channels,
with a differential error <0.2dB at any level. Maximum setting range is -3.5 ÷ +12.5
dBm.
The upper display line shows actual modulation with the low-frequency signal currently
present, whereas the lower line shows nominal input level for 100% modulation
(75kHz). Increasing nominal input level will decrease modulation accordingly,
modulating signal being equal.
