[WriteLog] NA Sprint RTTY messages

[Gary AL9A]

I'm setting up WL for the NA Sprint RTTY this weekend for the first time and 
have a couple of questions.

1.  The NA Sprint RTTY message examples at AA5AU's website shows the 
following suggested message for F8:

    %R%C NOT YET QRZ? DE AA5AU %E

The explanation for this message indicates that the RTTY Sprint rules allow 
dupes on a band as long as there have been 3 contacts since the last QSO 
with that station.  The message means I can't work you yet as I haven't 
worked 3 others since our earlier QSO.  I can find no mention of this dupe 
allowance in the current NA Sprint rules.  Was this an old rule of the RTTY 
Sprint that is now out of date and no longer applies?

2.  I'm using the MMTTY plug in for WL and am wondering about the NET and 
AFC buttons.  Don AA5AU says to NEVER use NET when CQing and NEVER use AFC 
when S&P.  In the Sprint you are constantly changing back and forth from S&P 
to CQ.  How do you remember to keep the NET and AFC buttons properly set 
when there is so much switching between calling and searching?  Or do you 
just turn them both off and go with the HAM setting?
