On Air Nets and Meetings

On the Air Nets

Peridically we have an on the air net on the RMHAM 449.225 MHz (141.3 CTCSS tone) machine in Denver. This net starts at 7:00 PM when scheduled.  This is not an reoccuring net but may be in the future when we can locate a net control operator. 

Here is the script used to call the EOSS net:

Face to Face Meetings

Edge of Space Sciences (EOSS), on the second Tuesday of the month, hosts a scheduled planning meeting to discuss operations on past and future flights.  Everyone is invited to attend.  The meetings are held at one of two locations to accommodate members who live north and south.  Meeting locations change each month. See the schedule below to find the location for the meeting you wish to attend.

For those members unable to attend, we host online meetings using the ZOOM video conference service so members that cannot attend in person can participate.  Login information is usually posted on the EOSS mailer on the day of the meeting.  Look for the authentication credentials and web address (URL) on that date.

Meetings start at 19:00 hours unless a specific exception is posted here and on the location directions page.  People often arrive 30 minutes before the meeting start time to socialize a bit before we get down to business.

It is also common for folks to pre-arrange an impromptu dinner at a restaurant near the meeting location. These dinners usually start around 90 minutes in advance of the meeting (17:30 hours). Information about this location is shared on the EOSS email reflector the day of or perhaps the day before the meeting.
