- Information related to the G7IZU Radio Reflection Detection page. The detection of meteors, aurora and other phenomena through the use of signals reflected from ionization in the upper atmosphere.
- SignalGen is a free (GPL) Linux (Xwindows GUI-based) utility that generates relatively low frequency signals with the use of a PC sound card. It is an entirely suitable replacement for a hardware signal generator if one doesn't require signals of a frequency higher than about 50 KHz. SignalGen creates any frequency between a fraction of one Hertz and an upper limit determined by your sound card's capabilities.
