Congrats on the two QSO's, the UK (G) and Puerto Rico (KP4), by the way.
Regarding a schedule today on 28.400, you call me. If that frequency is busy and you have to QSY, stay close to 28.400, say 28.395-28.405.
Don't forget your radio manners, too. Before making your call, ask if the frequency is busy. You would say, "QRZed, is this frequency busy?" Then listen. Then repeat, then listen. If nothing is heard, then call me three times then give your call. Then listen. Then repeat until we connect.
See you later.
