simple 4:1 balun

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

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

A Cost Effective Current-mode 1:1 Balun - A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors.

The Guanella 1:4 balun - A cost effective current-mode 1:4 balun can be constructed from two lengths of coax, two ferrite rods, some electrical tape, cable ties, a length of PVC water-pipe and some connectors. This form of 1:4 current-mode balun is named after G. Guanella.

PC Connection Cable for Yaesu FT100 - A simple cable for the yaesu FT-100 or FT-100D and a PC by interfacing audio and serial ports. In Italian

The SWDXer - SWDXer is the one stop resource for shortwave radio information. Articles include antennas and simple electronics construction.

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.

Fox Delta Satellite Tracking Interface Priority listing - A simple PIC16F688 satellite Tracking interface for yaesu ratators.

Relay Driver for Power Amps - A simple but complex relay driver for power amplifiers

Active attenuator - This active attenuator works as a simple mixer by WB2HOL

Simple adjustable passive attenuator - This adjustable passive attenuator works as a "waveguide beyond cutoff." It can be constructed in about ten minutes from parts available locally.

Simple anti-static device - With all the wire you have out, you may run into a problem with static buildup on the antennas. This static may try to make its way into your receiver, causing you major problems and damage that can run into a lot of money.

Small Unregulated Power Supply Project - Here's a simple power supply that can be used in many applications. It is not regulated , so keep that in mind for voltage sensitive devices , and of course you will need to understand how to select the correct amperage and voltage for the AC transformer.
