2 Meter 10 Element Quagi Antenna - This antenna was designed by N6JSX Kuby for Transmitter hiding. Fitting the requirements of directionality, high gain, and portability. This antenna was derived from the ARRL Handbook information on Quagi's and Yagi's; in the absence of two meter Quagi information, UHF Quagi dimensions were scaled into 146 MHz use.

6 element UHF Yagi antenna - A standard 6 elements design scaled for UHF application. All material used in this project are easily obtainable tubes and rods which is limited within a total budget of $18.

Antenna Theory - Introduction to Electromagnetics, Maxwell's Equations, Transmission Line, Models, scale modeling, constants

Antenna Tuning Unit - This homebrewed antenna tuning unit also incorporates a 50-ohm QRP dummy load, power meter (1 or 10 Watts full scale), and SWR meter

Dish 802.11 Wireless Networking Antenna - This antenna modification is for the IEEE 802.11b networking protocol that operates at 2.4 GHz. It can be scaled easily to the 5 GHz frequency used by IEEE 802.11a by simply scaling the dimensions on the feed can and the excitation antenna to 2.4/5 = 48% of the dimensions shown above.

Frequency Counter for VHF/UHF - DFD4A for bench top test equipment, has a built-in prescaler good to more than 3 GHz.

NOAA Space Weather Scales - The NOAA Space Weather Scales were introduced as a way to communicate to the general public the current and future space weather conditions and their possible effects on people and systems. The scales describe the environmental disturbances for three event types: geomagnetic storms, solar radiation storms, and radio blackouts.

Home Power Magazine - Independently published since 1987, home power magazine and homepower.com are resources dedicated to small-scale renewable energy and sustainable living technologies.

Meter - This meter scale drawing program is designed to have a computer do the hard work in making a precision scale for a d'Arsonval analog meter. The resulting scales will typically be nicer-looking than those found on many commercial meters.

GcmWin : Great Circle Map  ^pop - GCM is a freeware great circle map plotting software for windows, you can choose colours, scale, meridians, fields and or squares from the maidenhead locator system.

DigiPan  ^pop - DigiPan provides a panoramic display of the frequency spectrum in the form of an active dial scale extending the full width of the computer screen. DigiPan is the result of a joint effort between myself and Nick Fedoseev, UT2UZ, the author of MIXW32, and is intended to make PSK31 operation easier and more enjoyable for everyone.

MiniLog Beta - MiniLog is a very basic electronic amateur radio contact log from palm platform. It is intended for small-scale use, such as back-packing and emergency setups.

Multi-Instrument - Contains a PC sound card based signal generator. It can generate functions, multitones, arbitrary waveforms, burst tones, MLS, DTMF, musical scales, white noise and pink noise, and frequency/amplitude sweep. Fully functional free trial downloadable.
