EOSS Grid:

Suggested N�LP Grid Calculator Reference Point:

Since Punkin Center is located on a predefined (scoped by trackers with GPS) latitude Longitude you might consider using that as your reference point.

The lat/long is:

• 38.852083 decimal degrees north
• 103.70053 decimal degrees west

And that would be associated with Marty's X/Y coordinates of 25,10 as shown above

Notes:

HF Radio

Our regular net control station is unavailable this weekend due to prior commitments. We may or may NOT have an HF net. All I can say is ... tune it to the frequencies below and see what you hear.

We try and start an HF net approximately 45 minutes prior to launch on 7.228 MHz. If that frequency is busy we try 7.235 or 7.240 MHz.
