One VERY important thing I forgot to mention is the accuracy of your 
computer's clock. All of the WSJT protocols signals start and stop at 
precise times -- JT65 transmits from 1 second after the minute to 48 
seconds after -- and the decoder starts working immediately thereafter. 
If your clock is more than a few seconds off, you'll get fewer decodes 
and fewer stations will decode your signal. As timing errors extend much 
past 4-5 seconds, neither you or the other station is likely to decode.

You CAN set your clock by hand using WWV, but a better way is software 
that uses the NTP protocol to do it automatically.  I've recently been 
using a program called Net Time.
