X-Beam antennas - Two element X-Beam is a high-performance broad-band antenna that is ideal for Ham radio operators with limited space. X-Beams are inexpensive and easy to build. The performance of the simple X-beam is amazingly similar to larger, more conventional antennas by 4S7NR

Petlowany Three-Band Burner Antenna - The Petlowany Three-Band Burner is a simple, low-cost, trapless short vertical antenna which amazingly works on three HF bands (20, 15 and 10 meters). This web page contains pictures, performance data, and enough construction details so you can homebrew your own.

A wideband 80 meter dipole  ^pop - This worthy antenna is so simple and inexpensive you will want more than one by N6LF

Broadbanding the half-square on 80 meters - N6LF discusses a simple way to broadband the classic half-square antenna to operate in both the CW and SSB DX windows on 80/75 meters.

80 meters Short Dipole - The best antenna is the simple Dipole. If you have height, you even can put up a quarter wave vertical or an inverted, but sometimes you may need shorten version by 4S7NR

Bruce arrays for 80 and 160m - Antennas with gain and bandwidth for 80 and 160 meters band. Simple wire antenna capable of considerable gain

Rotatable Dipole for 40m-6m - This article describes a simple, inexpensive, dipole antenna that will rival the performance of a ten-meter beam.

ExpressPCB - Free PCB software is a snap to learn and use. For the first time, designing circuit boards is simple for the beginner and efficient for the professional.

Grig Radio Control - Grig is a freeware simple Ham Radio control (CAT) program based on the Ham Radio Control Libraries (Hamlib). It is intended to be highly generic presenting the user to the same graphical user interface regardless of which radio is being controlled. Grig supports the most commonly used CAT commands that are implemented by Hamlib, and integrates well with other ham radio programs like Xlog and gMFSK. Grig has been developed on Linux, but has been ported on Mac and Windows OS.
