All, I've asked Steve to get us a room with a projector for Friday evening at 7. He put in a request for us, and will let us know soon. We can start at the happy hour, then migrate over to the room to go over Tom's questions and Bill's specification documents
with my comments. <br>

If you have a chance, please read over Bill's documents before you get there and bring your questions.

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.
