SID Data Grabber

The SID Data Grabber is an application to help prepare an AAVSO SID report file from your Stanford/SARA superSID monitor log files. It offers a zoomable graphical view of the log data where you can click the graph to grab the times then puts them into the AAVSO format report file, ready for submission at the end of the month.

SID Monitoring Overview

So, what are we looking for? Here are a couple references of SID events and their influence on the ionosphere:

Capacitor Characteristics

The capacitor used to tune the Loop Antenna can be of various types. Depending on the type of capacitor you use you will see varying degrees of tuning sharpness. This is due to a parameter called the Q of the capacitor. The Q value refers the quality of the component as far as energy loss is concerned. Stated verbally, the Q of a component is the ratio of the energy stored to the energy lost.

A Minimal Gyrator II VLF Receiver

Arthur J. Stokes N8BN

The Gyrator II VLF receiver is described in another section of the SID equipment. The Minimal Gyrator II receiver described here is an attempt to show a lower parts cost receiver for solar monitoring that would be a suitable school project. The number of parts has been reduced to the essentials.

A Note About PC Board Layouts

Gyrator I & II - Parts Layout Mistake Resolution

The articles in section 2 and 3 of the SID Equipment list both show PC Board layouts that contain an error concerning the polarity of the power supply diodes and in the case of section 3, the output rectifier diodes. The following descriptions summarize the changes that should be made.
