[Elecraft] K3 Data transmission

[Lyle Johnson]

>  What harm would be done by allowing DTF in DATA A?

DTF is a special function for RTTY, and the K3 needs to know that thi 
sis a RTTY application to set it up, enable the decoder, etc.  The K3 
needs to know the tone pair in use.

DATA A is a general purpose mode that is unaware of the type or nature 
of the data being sent.

For special cases, there is always the possibility of making specialized 
features available in the K3 to support the spcieal case, very popular 
modes.  This is how PSK D and FSK (A and D) came into being as special 
cases of the DATA mode.

In general, DATA A assumes an external modem and (or computer+soundcard) 
and simply does its best to pass the data without distortion or 
interpretation.

So, no harm, but potential confusion.
