The Islands on the Air (IOTA) contest is this weekend, from 1200z Saturday to 1200z Sunday. I've always liked this contest, even though it is not all that high volume. The exchange is challenging in that station on Islands (who are the multipliers) will send RST plus a serial number plus an IOTA number (like EU185) while "normal" stations just send RST plus serial number. So, more variable stuff to copy, lots of multipliers to chase, both modes.
