After every QSO Z60A usually sends: Z60A UP

If Z60A never sends CQ, NA, QRZ, TEST, or UP, Skimmer doesn't recognize 
that they are calling CQ. Skimmer also likes to see the callsign twice in 
a row sent the same way. See my Contest University Presentation: 
https://bit.ly/UsingRBN2017, slide 22 (also linked from my QRZ.COM page). 
I need to update these slides for the 2018 Dayton CTU. 

I never heard of an issue with 0s not being copied well by Skimmer, but it 
makes a bit of sense since it is the longest character that has to be 
copied with no noise or QSB to confuse the CW decoding logic. 

Humans still copy CW better than computers, especially on HF with lots of 
QSB and noise.
