work from late 1998 to mid 1999. Mostly centered on the rotor and
antenna build out. Rotor Servo Problem 12/26/98, Move Rotor to
the Pole 12/28/98, Ready Antenna and Control Box 12/29/98, Antenna
in place and working 1/22/98, Antenna Monitor AS Of 1/29/99, Feed
Horn and LNA AS Of 1/25/98, FFT AS Of 1/15/99', Scope Repair
AS Of 1/25/99, Giant Leap Forward 3/2/99, More Rotor
Problems 3/14/99, Horn and LNA Installed 3/30/99, First
Drip 4/2/99 |

I
picked up a radio for the system at the Dayton Ham Fest and spend most of
the time working on it. WiNRADiO installed 9/5/99, WiNRADiO
receiving the Weak Signal Source 9/13/99, SETI Net Dynamic Address
9/27/99, RF Test Range 10/10/99, WiNRADiO
1500 AGC Defeat 10/14/99 |

I
decided that someone should look at unifying the data collection process
and started designing SML. Data Format
FITS & XML 10/27/99, Baseband Output,
Phase Noise Measurement, Software in Progress - (1/15/2001), |

During
testing I ran into a lot of noise in the system. This prompted the
design of a front end filter. Comb Line Filter
- (1/21/2001), 20 KHz
receiver Bandwidth Modes - (3/15/2001), Filter
Installation - (3/25/2001), Enclosure |

More
concentration on the software side of the system in this chapter. I
was able to lock the antenna to a point in the sky using the SETI Net
Clock software Antenna
Position Lock ( 6/15/2001) and was able to integrate a sky
map to show just where the antenna is pointed Integrate
the sky map (7/9/2001). I was also able to create the
first waterfall image of the sky when locked and tracking Waterfall
(9/9/2001). The recording and playback of the data stream
proved to be a daunting task only partially solved during this period Recording
and Playback of Raw Data -(11/1/2001 ) and finally I tackled
the ever-present problem of making the waterfall display presentable in Normalization
of the receiver band pass (12/7/2001). |

Receiver
chirping and the decision covering receiver integration is covered in this
chapter. Also contains one of those rare items - an epiphany
I must look for myself

This
chapter covers advances in SML, the Antenna Rotor repair
task and the development of an Audio subsystem block
diagram |

Chap. 8 |
During this period I managed to get a working SML and WAV file connection
moved SETI Net to a commercial server |

Chap. 9 |
The initial steps toward a SETI database was started
Database development
for SETI data (2003-12-05 2004-02-11) and then continued
Database development
for SETI data (2004-02-12 to 2004-04-06).
I did a fair amount of
thinking about the database
Thinking Out Loud (2004-04-06 to
2004-05-24 ) But little actually got done. Returning
from a long RV trip I found that the rotor had failed. This required
a YARR (Yet
Another Rotor Rebuild (2004-05-24 to 2004-07-08)) |
|
Chap. 10 |
I finished another antenna software rebuild
(Antenna Software Rebuild (2004-07-09 to 2004-08-01)).
This chapter also contains a block diagram of the sound system in
Windows computers and is needed to understand how to configure it for SETI
work. The SETI File Archive was put in place in a prototype
condition (2004-08-01 to 2004-09-03) |
