Quantum Antennas - 146/446 Mhz Dual Band, High Gain vertical Antenna

IPS - HF Systems MUF maps and prediction charts - These pages provide general propagation advice for HF communicators. Information available includes inferred global propagation conditions, real time HF fadeout coverage charts, regional ionospheric vertical MUF maps and Hourly Area Prediction charts for Astralia and Asia, Europe and North America

Tower - Windows program for analyzing vertical antennas. This program shows the resistance and reactance to be expected looking into a cylindrical metallic tower over a perfect ground. It gives a useful approximation of the values to be expected in a real-world situation.

DTMF decoder - A very easy to use program to decode DTMF dial tones found on telephone lines with touch tone phones. The DTMF Decoder is also used for receiving data transmissions over the air in amateur radio frequency bands.

ATPDEC - Atpdec is an open source program that decodes images transmitted by POES NOAA weather satellite series. These satellites transmit continuously, among other things, medium resolution images of the earth on 137Mhz. These transmissions could be easily received with an inexpensive antenna and dedicated receiver. For more information about receiving POES satellite images consult the rig site.
