2. Overview  Test Experiment Design  Testing Measurement Data  Demonstration  Kit Issues  Solutions

3. Experiment Design Red dot represents handheld CW beacon Person in car drives in oval formation around operator Corresponding LEDs light up in the direction the signal is coming from accordingly System will be utilized in foxhunting upon completion 0º 270º90º 180º

4. Experiment Design

7. Testing Measurement Data Measurement data for the small scale testing will be mostly qualitative data Testing will focus on relative accuracy and consistency of the system This data will reflect the usability of our system at the CW beacon frequency (146.565 MHz, 2- meter band) and further calibration techniques

8. Testing Measurement Data Note: One data sheet for each kit. Time and location will be determined from measurements from both kits

9. Demonstration “Beeline Big Beacon” Programmable 440 MHz beacon Adjustable frequency for package dissemination Morse Code reads: W1WSU Command

10. Issues First Kit Issues Finding the CW Signal Audio signal sporadic Second Kit Assembled, not functional Pending functionality of first kit Once problems are diagnosed, second kit will become functional quickly

11. Solutions

12.  Functional rigging persists  Utilize instructional videos  Documentation provided from Ramsey Electronics is vague  Further testing will continue with CW beacon source

13. Yagi Antennas Reconfigured RG58 connection point

14. Sponsors  The Ohio Space Grant Consortium (OSGC)  Wright State University Curriculum Development Grant  National Science Foundation (NSF)

15. Summary  Test Experiment Design  Testing Measurement Data  Issues  Solutions
