[Elecraft] K3 filtering

The variable roofing filter will have no impact on transmit 
bandwidth as the K3 always transmits through the 2.7 or 2.8 
KHz filter (until ESSB is available and uses the 6 KHz filter). 

However, you can accomplish modest tailoring of the transmit 
bandwidth using the equalizer to cut highs/lows as needed or 
desired.
