Overview • Test Experiment Design • Testing Measurement Data • Demonstration • Kit Issues • Solutions
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 270º 90º 180º
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
Testing Measurement Data Note: One data sheet for each kit. Time and location will be determined from measurements from both kits
Demonstration • “Beeline Big Beacon” • Programmable 440 MHz beacon • Adjustable frequency for package dissemination • Morse Code reads: W1WSU Command
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
Solutions • Functional rigging persists • Utilize instructional videos • Documentation provided from Ramsey Electronics is vague • Further testing will continue with CW beacon source
Yagi Antennas • Reconfigured RG58 connection point
Sponsors • The Ohio Space Grant Consortium (OSGC) • Wright State University Curriculum Development Grant • National Science Foundation (NSF)
