3.2.3.3
PROCESSOR MODE:
Shows the
processor type. The unit can be prepared for FM
or AM stations. This is defined in factory, because
requires some internal changes in the circuit
board; as well as a different programming of the
flash memory with the corresponding constants for
the AM band.
3.3 Adjusting the modulation
This adjustment requires an oscilloscope,
increasing the level of the processor output
(from
Output Setup on main Menu)
.
The output
AM TX
give up to
+12 dBm
in
balanced mode.
The
negative peaks
will have to reach
exactly at
100%
, whereas the positive peaks can be fit
between 110 to the 130% using the asymmetric
modulation adjustment.
Exceptionally some modern transmitters supports
up to 150% of positive peaks, although an so
extreme adjustment generally deteriorates the
sound quality.
