Six meters is the band he is pointing at, and the reason is a date. Sunday is an activity day his friend Mike is trying to fill, because the usual problem with 6 meters is that you can listen and hear nothing.
He wants the date to be obvious. May, the fifth month. The 25th day. The 25th year. He lines that up with 6 meters and says he hopes to hear people Sunday, one way or another. A link to Mike’s own video is in the description. If you are going to call, he wants a comment with where you are and when you will be on, so someone can try to reach you.
