VK5BR 20-40 Metre EH Antennas  ^pop - How to construct a very small but efficient Antenna with PVC Plumbing tube and discarded fruit cans. - Just the thing to fit in a small space such as the house attic

I4SBX EH Antennas - Three eh antenna plans for 20 40 meters bands.

Compact Restricted Space 40 Meter Wire Antenna - An inexpensive easy to construct compact 40 meter wire antenna that will fit in a 20 feet by 20 feet space

End-fed vertical j-pole and horizontal zepp vertical - There are many incorrect ideas and claims surrounding end-fed vertical antennas (like the I-Max 2000), end fed horizontal antennas, Zepp, and J-pole antennas. This article describes it.

G5RV multi-band antenna - Multi-band centre-fed antenna capable of very efficient operation on all HF bands, specifically designed with dimensions which allow it to be installed in gardens and other open spaces which accommodate a reasonably-straight run of 31.1m (102 ft) for the flat-top standard model.

Low reactance multiband center feed wires - An antenna system is more easily interfaced to a radio when the input reactance at the feedline terminals is low or close to series resonance

Concealed DSS J-Pole - The idea here is to have my antenna high in the air, in free space, with the dish mounted close by for concealment.

Building the J-Pole Antenna - They're tricky, but they're worth it! By KA1FSB

HF J-Pole antenna - A Simple Nondirectional Antenna for Ten Meters QST February 1950, Easy to build J-Pole antenna for restricted space.

The Moxon Antenna - The Moxon antenna is sort of a two element yagi with the elements folded and spaced to eliminate the need for an impedance match.

OH7SV Matti Hohtola Ham Projects  ^pop - The most modern QRP transceiver in 2004,Direct Conversion HF Transceiver with DDS LO, 50 ohm to 200 ohm HF wide band transformers, Wilkinson splitter for RX measurements, Windom baluns 2001/2004, Ferrite rod antenna for 80 meter, Magnetic Loop Antenna for 80 m, Mascot Switched PSU 9320 modification to 8A peak current, 150W MOSFET linear amplifier for 80m, 80 m HF SSB/CW Transceiver

County Hunter Net Procedures - The main purpose of the county hunter's net is to facilitate the operations of those hams seeking to work all counties in the United State. It is also a useful place for CW emergency communications as there is almost always someone monitoring the frequencies.

PC to RTX interface - Schematics for IC-706, IC-718, IC-756PRO, TS-570, TS-870, and simple universal S.B. interface All three interfaces presented on this page employ galvanic isolation of the transceiver from PC computer. Audio paths are separated by transformers, optocouplers serve to separate the digital paths (PTT and RTTY keying).

QuickRecord - QuickRecord is a compact application for recording and playing sound on a Microsoft Windows PC. It works on Windows 95, 98, Me, NT4, 2000, and XP. Recording and playing back directly to and from disk files, QuickRecord 2 maintains the simplicity of the standard Windows Sound Recorder applet but without the restrictions.

AZMap - Azimuthal maps generator - AZMap is a freeware Windows program for the Windows PC which will generate, display, and print an Azimuthal-Equidistance (A-E) map of the world, centered at any point on the surface of the earth (except very near the poles). The A-E map is also known as a Great Circle map since straight lines from the center point to any other point always fall along a great circle path and represent the shortest distance between the center and that point
