Jim Moss (N9JIM) called the meeting to order at 5:10 PM.
New Business:
The new 50mhzandup@groups.io email reflector is up and running.
Mt Allison beacon status. The 24, 47 and 80 GHz beacons have been verified to still be working, however the 80 GHz beacon is 40 KHz below the published frequency.
Cambium Networks has asked the FCC to allow shared use of the 10 to 10.5 GHz band using a Automated Frequency Coordination system. This prompted a discussion about what the group should do to respond. The Northern California Spectrum Working Group is soliciting information about current amateur VHF/UHF/Microwave usage with an eye toward developing new band plans for those amateur bands in northern California. Jim Moss will be sending out a survey via the email reflector to gather information about the bands the group members are active on.
122 GHz activity. There was brief discussion of current 122 GHz activity.
Holiday Dinner. A poll was taken to determine if there was interest in a holiday dinner this year. The decision was to hold the holiday dinner. See the announcements section above for location and time.
That ended the formal part of the meeting. This was followed by a round table discussion of attendees’ current activities and projects.
