List of MMSI numbers

I wanted to list my MMSI number so other boat owners could call me. I entered Tony s, Phil and Mike's numbers on my radios. Mine is
338068038
I want to try it out. when I enter a position request it goes to chanel 70 and will try to send the request to the person I entered. After 30 seconds or so it stops sending the request... No one was available today, oops, forgot the antennas are down and I am at my house. Send me a note if you want to try it out. I live in Lemon Grove and when I turn my radios on, I can talk with people at San Clemente and Ensenada. I live on top of a hill. Talk to you later.
