| Location | Bay |
|---|---|
| Frequency Range | 426-442Mhz |
| Condition | Xbee ON, Antennas next to each other |
| Notes | Basically the worst case that can occur. Raises noise level to about 75dbm. Happened when antennas were perpendicular to one another. This is why we should keep the antennas away from each other |
