[Elecraft] Macro for setup of K3S for WSJT

[Don Wilhelm]

Dick,

While it is true that the input *can* be Line In for DATA A - it is not 
the default (like on a Factory new K3 or K3S, when you first go to DATA 
A mode you must use the MIC SEL to set it to LINE.  After doing that, it 
will be 'sticky'.

FT8 uses a very wide bandwidth (if available), and using the 13kHz 
filter, you can stretch the K3/K3S bandwidth to 4kHz.  The bandwidth is 
limited to 4kHz because there is a low pass filter that takes away the 
high frequency hiss and noise that is present on the bands, and several 
hams find quite objectionable when listening to it for a significant 
period of time.

While that high frequency "crud" is not a problem for digital modes, 
there is not a way to turn off the LPF.

73,
Don W3FPR
