A Lowband Antenna that is Almost Free  ^pop - The Shunt-fed Tower, an effective Low Band Antenna, uses your beam as a capacitive top-hat and only needs a simple feed network and a good ground system to work DX on 80M and 160M.

QM7 7 elements 144 MHz Yagi-Uda Antenna - The QM7 antenna is a simple 7 elements Yagi with 3.70 m boom length for the lower 144 MHz SSB/MGM band, used it mainly for Sporadic-E and MS contacts. It exhibits a forward gain of 11.35 dBd; i.e. 13.5 dB forward gain over the isotropic radiator, while the F/R is about 12.5 dB

Portable Yagi for 144MHz - Simple 7 element Yagi is ideal for portable operation.

80M Vertical antenna with capacitance hat  ^pop - Simple wire antenna cheap to make, using readily available materials, Low angle radiation, with rejection of high angle signals Wide bandwidth, with resonance at the 80M DX window (3.790-3.800 MHz); and Maximum height is 40 feet

Setting the SWR of Your Antenna - SWR (standing wave ratio), is a measurement of how efficiently your antenna system will radiate the power available from your radio. In simple terms, your radio would like to radiate all of its power, but can only do so if the other components cooperate

Half square antenna - The elevated half square antenna is a very simple antenna that can be constructed from common materials yet gives significant improvement over a dipole at the same elevation. Ground mounted versions of this antenna are commonly used in amateur radio for 75/80 and 160 meter bands

Win APRS - Automatic Position Reporting System windows program, allow monitoring of real time geographical information such as the position of vehicles, the status of weather, radio direction finding and more.

APRS-Beacon - The purpose of the APRS-Beacon is to provide simple APRS-compatible position beacons for up to three Objects. It is designed to 'stand alone' and does not monitor other traffic on the frequency. It can use a single-port TNC (in 'native' mode), a single- or dual-port TNC in Kiss mode or the AGW Packet Engine in order to transmit on up to four radio ports.(When running with AGWPE, APRS-Beacon will also work with Windows 2000)

WinGrid & DOSgrid - Gridconv.zip contains Wingrid.exe and Dosgrid.exe, DOS and (16 bit) Windows versions of a simple program that converts between NGR, Maidenhead Locator, QRA, and Latitude/Longitude. They are copyright, but freely distributable for no charge.

YG-PSK - Simple PSK31 and RTTY program based on the AE4JY PSK engine. Logging inlcudes 10-10 and VP number. Exports to ADIF and CSV.

Satbuster - SATBUSTER for Windows is especially designed for satellite visual observers and trackers. Its users, mainly amateur astronomers and radio amateurs, appreciate both the accuracy and the simple to use graphical interface.The software is aimed to hobbysts. However a growing number of plain folks are starting to use this tool to recognize and look at the International Space Station and the Space Shuttle during its missions too

SpectraScope - SpectraScope is a simple Windows interface program allowing your computer to view up to two audio waveforms in either the time or frequency domain. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer. The useful frequency of operation is 20 to 10,000 Hz in the time domain and 20 to 20,000 Hz in the frequency domain. The program uses the computer sound card to capture the audio input.

Programming VHF/UHF Radios - Programming a new VHF/UHF radio usually proves to be a frustrating experience for most new amateur radio operators. A new radio must first be programmed for simplex and repeater operation before it can be used to communicate with local hams.
