[Elecraft] CW Transmit Filter Bandwidth

[Don Wilhelm]

Byron,

The K3/K3S is designed to use the filter that is installed "stock" in 
all transceivers, so you need to select the 2.7 (or 2.8) filter for CW 
(or any other mode except AM, FM or ESSB) for transmit.

Requiring a 1kHz filter for CW transmit would require that filter be 
included in the basic package and would increase the price of the 
transceiver.

This sounds like a 'curiosity' question - the K3/K3S works fine with the 
2.7/2.8kHz filter for CW transmit.

73,
