Commitment is one thing, experience is the other. It is no good being committed if you are not aware of what is happening. Knowing what to listen for is mandatory if you are not miss the one and only chance of working that DXpedition. Listen on 28.885 and 3.718 for who's where and when. Always try and find out the facts - when, where, times of operation, beacons, callsigns etc .
Every bit of information helps.
They all start early morning, peaking at 0852z. Very rarely they start earlier and sometimes they can go onto 1200z, but 0900z is the best time to listen. Beam headings are usually non-great circle but I would suggest that a heading of 60 degrees be used as a starter. Headings vary between 30 and 129 degrees. The first thing to listen for is strong video coming up from the LF part of the band.
