Small styrofoam loop - Contructing a loop using a styrofoam block

Thinking about Ideal Loops - Loop antennae have been used from ELF to UHF since the beginning of radiocommunications. At low frequencies, the main problem for loop antennae is to have enough sensitivity; the antenna being very small respect to the wavelength the collected energy is also small. To increase the output level the loop may be made resonant, so loosing it%u2019s intrinsic aperiodic characteristics.

A $20 HF mobile antenna - A few hours of fun with PVC and wire and you’ve got yourself a respectable road radiator. The antenna consists of little more than some PVC pipe topped by a RadioShack replacement whip antenna and a couple of coils made from a small roll of #14 house wire.

Pfeiffer Quads - The Pfeiffer Quad was described in QST and has the desirable feature that it is smaller than a standard cubic quad but does not compromise performance very much. The Pfeiffer design is rather difficult to construct because of the complicated linear loading networks required.

Digital Smart Antennas DiSA - Digital Smart antenna (DiSA) Automatically Adjusts over a wide band of frequencies.

SoftRock-40 - The SoftRock-40 is a small, low-cost, good-performing "software defined radio" receiver that plugs into a computer USB port and delivers I-Q audio signals to the computer's sound card. It was designed by Tony Parks, KB9YIG and Bill Tracey, KD5TFD as an "SDR sampler project" for hams everywhere to easily try out software defined radio.

SmartSmith - A smarter version of the Smith Chart program. It allows you to dynamically generate impedance point plots as you configure each design element of an impedance matching network. Has an extensive Help file with a Wizard that tells you what steps to take in designing a matching network for a given load impedance. Complete Windows installation kit by w9dmk

Morse Maker - MorseMaker is an up-to-date replacement for the Morse Machine shown further down this page. It has been re-written using a different programming language and is now entirely 'stand-alone' requiring no run-time support files. This version also works with Windows XP and can use the soundcard but please note that, unlike its predecessor, it does not split the alphabet into smaller 'learning' blocks and does not incorporate the Morse reader.

RigResident - RigResident is a small program for RIG control, which does allow to set and read data of connected tranceiver (frequency, mode etc). RigResident supports more than 70 TRX models from ICOM, KENWOOD, YAESU and Ten-Tec.

Antenna elevator system for amateur satellites  ^pop - Smart homebrew antenna-ELEVATOR system with linear actuator. The actuator is a cheap and heavy tool with high enough torque, ideal for elevation systems, but in practice it needs quite an effort in order to operate correctly in your homebrew antenna system. This page inform you of the actuator's secrets.
