used to determine the bandwidth you are using on any mode. (Yes, you need

1.8kHz filter for SSB , it is just not necessary. If there is
a signal 2kHz away inside the 2.7 but outside the
1.8 and 100dB above noise you are going to have problems with
their IMDs anyway.
Few people will benefit from narrow SSB filters, but no point
In crowded band conditions, narrow filtering is often helpful. In
particular, for SSB contests, a receive bandwidth of 1500-1800Hz is very
effective. For me, 1500Hz (300-1800Hz) works great on the K3. There is no
intelligibility above 1800Hz that is useful in a contest QSO. If you think
