In the previous example, the BFO was set for the same frequency for
all three filters. Figure 8-2 shows the same filters as used on CW
Reverse (opposite-sideband CW). In this case the BFO must be at a
frequency above each filter, so the BFOs settings are all different. The
K2 compensates for these changes in BFO setting, however, so when
you use CW reverse you'll still hear the 1000Hz signal shown in
Figure 8-1, and the filters will function identically.
