[RTTY] Getting spotted by RTTY skimmers

[Joe Subich, W4TV]

CR/LF is fine for the *beginning* of a macro as it does not move
your call down the screen.  It *ending* a macro with CR/LF that
causes chasing the call up the screen.

On a proper scrolling display, CR/LF at the beginning of the macro
will put your call at the left edge of the bottom line of the RX
window ... generally right under the mouse cursor unless the user
is making some rather gross mouse movements ... and where the user
does not need to search for it in the garble at the end of the line.

73,

    ... Joe, W4TV
