275 - SETI Database On The Web - 2012-05-14

Now that the Control Panel, and all its modules that make it run are finally cooking along I can turn my attention back to making the database visible on the web site.  This is the short term goal:

  • Demo - Build a demo application using the RAD PHP tool set,

  • Grid - Populate a simple grid control

  • LocalHost -  Have it show up on the local web site. 

This is a cook book for that first task (click on the thumbnails):

     
Connect to dB   Open Connect

274 - False Positives - 2012-05-12

The system is working well - might be too well.  I'm getting a lot of hits as I scan L4 this afternoon.  About two an hour.  When I go back to falsify the hits I'm having trouble seeing them in the waterfall and the detection logic is not re-finding them either. 

 

One just came on.  Lets look at it:

Waterfall clearly shows two signals.  One at 1375,796,590 the other at 1375,796,809 - 220 HZ apart.  When I go out of Alarm mode and restart the SpecAna and Waterfall I cannot find the signals again.  I don't think the receiver or the antenna changed during the switch over.

What could be causing this?

 

273 - Operating Better Than Ever - TO DO List 2012-05-11

The changes I made in the Spectrum Analyzer and the Control Panel have smoothed out the operation greatly.  There are still many to do items:

  1. State Change - Moving from Alarm state to OFF should NOT shut off Spec Ana and Waterfall. Needed for falsification.

  2. Defaults -  SpecAna to 32 K, 16mV, 10 Seconds

  3. Move on Falsification - After a hit is falsified the receiver must move ahead by 10 KHz

  4. Water - Change where the waterfall starts on the screen

  5. Power Point - Pickup background for PowerPoint

  6. Antenna Com Port - Fix Antenna stumble on first click

  7. Button - Make buttons on Receiver a bit larger

  8. Sky Map Go To - Fix the Sky map drive to button on the Control Panel
