[RTTY] Getting spotted by RTTY skimmers

[Lee Sawkins]

Starting your call macros with a couple of spaces does as well as <CR><LF>
and has he added benefit of not causing the text to scroll down the screen
if you press your callsign button several times.  All macros should start
with something other than a printable character as many times they get
tagged onto garbage characters and do not get decoded as intended.  Sending
your callsign twice with no leading and ending non printing characters will
result in no callsign being decoded without extra characters.  This slows
things down as the receiving op has to manually enter your call with the
keyboard.

Start your macros with <CR><LF> .... that will make sure you don't get
picked up with the trailing CW or TEST from the previous station.
