"7. Skimmers only spot callsigns that are accompanied by certain
keywords, such as CQ, TEST, etc. If I send TU AB7E at the end of a
contact in a run (as I usually do) I probably won't trigger a Skimmer
reaction. There may be other distinctions that have an influence. For
example, while CQ'ing I wonder if "TEST AB7E" or "AB7E TEST" is more
likely to work."
This suggests there may become an explicitly defined "best practice" of
structuring CQ's when running. Just like the specific order of the exchange
elements that is preferred during the Sprints.
