20m mini loaded dipole - It is very simple to build and you can tune it in your shack room

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

9 band vertical HF antenna by RW3XA  ^pop - Simple vertical radiator with matching box. No traps, no tuner required.

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

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.

B-Log - B-Log is a very simple, free-form logging program that offers useful features for the shortwave or scanner hobbyist, including SWBC listeners, AM-BC listeners, utility listeners, and amateur radio operators. The program is both simple to learn and use, and very powerful.

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.
