CQ100 is a VOIP system that requires all users to be licensed. Some laugh at it and say it isn't real radio. That said, when 75 meters goes bad in the evenings and our net can no longer continue - we switch to CQ100 and can continue on. We also have a section of the net that is only CQ100, to include net members that have moved south and/or can no longer have antennas. Call it "not real radio" all you want. However, it provides a form of ham radio that fills several needs. More info at: http://www.qsonet.com/index.html It is cheap entertainment for the ham. I use it as another mode.
