All Stations please monitor 7.268 MHz LSB
04/21/2013, Chicago

Art, NK8X
Good suggestion from Art, NK8X:

We are requesting all stations to please monitor both Marine VHF Channel 16 (156.800 MHz FM) and Ham HF 7.268 MHz LSB after the net - 24/7 over weekends while on the boat or at home.
Local Ch 16 emergency traffic can then be relayed long distance via Ham HF.

This will greatly enhance boating safety on the Lakes by providing more listening ears.
