Depending on MODE the following Xtal-filters (analogue filters) and passband
shifts are available (using WIDTH and SHIFT control):
Width
1.8 / 2.0 / 2.4 / 2.7 / 3.1 / 6.0 kHz
Shift
100 Hz - 600 Hz in 100 Hz steps
The 2.7 kHz filter is the allocated roofing filter for SSB
Width
0.5 / 1.8 kHz
Shift/Pitch 400 Hz – 10000 Hz in 100 Hz steps
The 2.7 kHz filter is the allocated roofing filter for CW
Width
6.0 / 15 kHz
Shift
n/a
The 6.0 and 12.0 kHz filter are the respective roofing filter for AM
Width
6.0 / 7.5 / 15.0 kHz
Shift
n/a
The 6.0 / 7.5 and 12.0 kHz filter are the respective roofing filter for FM
For 7.5 and 15.0 kHz the 10.7 MHz Xtal filters are bypassed.
For FM the "bandwidth" is related to the audio response only; RF-bandwidth
remains always 6 or 12 kHz respectively
Depending on MODE the following bandwidths (through the combination of
digital and analogue filters) and passband shifts are available (using WIDTH
and SHIFT control):
Width
1.0 / 1.2 / 1.4 / 1.6 / 1.8 / 1.9 / 2.0 / 2.1 / 2.2 / 2.3 / 2.4 / 2.5
2.6 / 2.7 / 2.8 / 2.9 / 3.0 / 3.1 / 3.2 / 3.3 / 3.4 / 3.5 / 4.6 / 6.0 kHz
Shift
0 Hz – 600 Hz in 50 Hz steps
The 2.7 kHz filter is the allocated roofing filter for SSB
Width
50 / 100 / 200 / 400 / 500 / 600 / 800 / 1000 Hz
Shift/Pitch 400– 1000 Hz in 50 Hz steps
The 2.7 kHz filter is the allocated roofing filter for CW
Width
4 / 5 / 7 / 8 kHz
Shift
n/a
The 6.0 and 12.0 kHz filter are the respective roofing filter for AM
Width
2.4 / 2.5 / 2.6 / 2.7 / 2.8 / 2.9 / 3.0 / 3.1 / 3.2 / 3.3 / 3.4 / 3.5
4.6 / 6.0 / 7.5 kHz / 8.0 kHz (Bypass)
Shift
n/a
The 6.0 and 12.0 kHz filter are the respective roofing filter for FM
For > 4.6 kHz the 10.7 MHz Xtal filters are bypassed.
For FM the "bandwidth" is related to the audio response only; RF-bandwidth
remains always 6 or 12 kHz respectively
