Whatch at beacons transmitting in real time. This page contains a self refreshing table that displays every 10 seconds the current transmission schedule of the international beacon project. Tune your radio and check the beacon you are hearing. (by NCDXF)
The fan dipole antenna as an alternative to the paralled dipole antenna, to achieve a larger bandwidth and a better tuning by decreasing elenment influences.A project based on the W6HDG original concept.
NVIS antennas, also known as Near Incident Vertical Skywave antennas have a high angle of radiation. Something on the order of 60 degrees, to straight up to 90 degrees. A portable, easy to setup and cheap nvis antenna project. (by Mike Thompson)
Free windows world map application display current time, sunrise and sunset, greyline map, dx stations, requires windows 7 or higher. The program includes three resized Natural Earth maps which have been resized to 4k or slightly less. By Simon Brown G4ELI better known as the inventor of Ham Radio Deluxe. (by G4ELI)
An inexpensive spectrum analyzer for the radio amateur, with a respectable performance and a quite good dynamic range. Schematic and basic information on how spectrum analyzers works. (by robkalmeijer)
A six meter band 3 element yagi beam antenna project with shortened elements using coax cables with the outer ends stripped and the center conductor shorted in somewhat of a Bazooka antenna. (by KK4ICE)
A very efficient 80 meter Counterpoise antenna designed to reduce ground losses from inadequate radial systems beneath inverted L antennas, a project by DM2GM and DM4IM based on the original K2AV antenna concept. (by DL0WH)
Consider installing a stealth vertical loop antenna if you live in a place with no antenna restrictions. Full wave loop wire antennas allow you to be on the air without installing evidente external aerials. (by KN9B)
This Antenna project is a bit more complex than other omni antennas for satellite use, but it is much easier and cheaper than a standard tower mounted circular polarized azimuth and elevation rotating beam system. (by w6shp)
A home made portable vertical antenna, that with a single 1/4 wave counterpoise wire is possible to achieve less than 1.5:1 SWR on 40, 30, and 20 meter bands. It is basically a center load, shortened ground plain vertical antenna. (by WB9DLC)
This article describes a project of asymmetrical hatted vertical dipole, a portable antenna that can be used for field day operations, sota, campings or even for fixed installations. This is a freestanding 20-10m antenna that is really easy to build, easy to tune and relatively easy to carry. (by John Huggins)
