Notes and Details
First flight of the BadgerCub and first ever uplink to a payload. Uplink to CC1111 tested. Sacrificial flight to test uplink range. Strong winds carried the payload out to the middle of the channel and uplink was successful to a range of approx. 190km. More details on the uplink method are on the CC1111 page.
We made a scatter plot of successful string uploads plotting range from the ground station against transmit power used. The payload antenna was a 1/4 wave whip with 4 radial grounding elements. The ground station had a 7-element yagi and an IC-7000 with maximum transmit power 35W. A couple of times during the flight we attempted to see the power minimum for successful uplink and these can be seen as the vertical arrangements of points in the plot.
