</div>1. Need cost estimates for the Clock, DE, RF, and Magnetometer modules.<br>2. What is the schedule for the modules, testing, prototypes?<br> a. Data Engine<br> b. 2-chan RF receiver<br> c. GPS Clock<br> d. Magnetometer<br> e. Other ? SBC, Power supply, etc.<br>3. Each module will have a unique manufacturer serial number based on some PROMs that have this capability. Any issues with the number or format?<br>4. Do we need to create any videos describing what the project is, what the objectives are, status, or other?<br>5. Only a little discussion so far on power supplies. General agreement on +11 to +15 VDC source. We need to come up with the general supply</div><div dir="ltr">distribution scheme before board design and layout commences.<br> a. Have the DE or Interconnect board condition all power.<br> b. Have each module condition any critical power it needs.<br> i. Voltages feeding critical analog circuitry (Clock Module, RF Module).<br> c. Have an external power conditioning module.<br>6. HAMSCI 2020<br> a. Any more information on the location?<br> b. Should we plan a demo of TangerineSDR or the completed parts?<br>7. Receive Antennas. Mike Pappas has acquired a calibrated filed strength meter, we discussed seeing if DX Engineering would let us measure a</div><div dir="ltr">production lot of antennas (10?) to determine the field strength sensitivity and variance.<br>8. Do we need a test plan for the system?<br>9. Upload data compression appears feasible (3:1 ?). Do we need any study or proposals of how much data we are asking folks to upload? Or is</div><div dir="ltr">this better to determine experimentally?<br>10. Discuss and review the Local Host Functional Specification.<br>11. Discuss and review the Central Control Functional Specification.<div>
