If you want to optimize your Field day score, consider sending 10 messages from your site via RF for 100 points. Then, receive your ARRL Section Manager's Field Day message via email over a Winlink link, for another 100 points. See the Field Day rules for all the info.
To make things easy, Winlink operators have set up a database of Field Day site stations that will exchange messages with you. Check out the Winlink forums in the support area and search for 'Field Day".
