[RTTY] "DE" is dead

[Iain MacDonnell - N6ML]

I think it's already been stated, but including " CQ " at the end of
your CQ and TU messages is a good idea anyway, as it allows someone
who tunes across your signal during the message to learn that you are
soliciting a new call without having to wait for your next CQ, so...

" CQ RU N6ML N6ML CQ "

would be my recommendation... so someone tuning across me sees "ML
N6ML CQ " and can jump right in...
