To attempt to debug the 2Hz noise seen on the kryptons during this project, I have set up part of stn #4 in the lab:
DSM #5
CSAT #0671
GPS for timekeeping
First, I used KH2O #1133 and saw no noise on an output voltage of about 0.21V. I blocked the optical path and saw no noise at 0.00V.
Next, I swapped in KH2O #1394 (the actual krypton used at stn #4. It now outputs 1.43V, but also had no noise. Also no noise when blocked and reading 0.00V.
Next, I added the cradlepoint with a modem back into the DSM. The modem wasn't connected (due to placement in the room), so no data transfer was occurring. Still no noise.
That's it for now. Next steps would be:
- Move to get cell coverage
- Add 2 TRHs
- Add barometer & prop
- Add solar panels
