Horizontal polarized omni directional 50MHz Antenna. This antenna is intented to use in a contest station as a second system beside the stacked yagi beam system. An omnidirectional systeem can be an advantage when it comes to short openings on wich the operator must react quickly.

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.

A very simple experimental short wave radio receiver. This is basically just a crystal radio with two stages of transistor amplification afterwards made with scrap components.

QrssPiG is short for QRSS (Raspberry)Pi Grabber able to process I/Q stream from an rtl-sdr, HackRF or other sdr devices

Sort of similar to the one of the 6m omni. Instead of using twin-lead, this design makes use of a more or less regular double bazooka antenna (coaxial dipole). Your attention shall be drawn to the available standart literature, such as Rothammel. In order to "compute" the dimension, Karl Rothammel mentioned that the total length of the dipole shall be 95% of the free-space wavelength. The short-circuit bridges (closing the folded dipole) are to be placed at a distance-fraction being equal to the velocity factor of the coax cable used, which will be 66% using RG-58 or RG174.

Amplitude Modulation Forever for ham radio operators, shortwave listeners and collectors

When a broadcast antenna is to be placed on top of a building, there are special problems of feeding and grounding. The radiator is usually electrically short, that is, much less than one-quarter wavelength high.

You can shorten a vertical antenna by using a loading coil. This online calculator tells you how the amout of inductance your loading coil will need to have.

It showcases a high-quality world map along with the Sun's position, sunrise and sunset times, the terminator, coordinates, QTH locator, azimuth, azimuth map, current DXCC list, Aurora, and WWV Geophysical Alert Messages. Additionally, it provides the SFI, X-Ray, Kp, and Ap indices.

DL1OFC, operating from Hankensbüttel, Germany, shares insights into the fascinating hobby of amateur radio. While the station has been on hiatus since 2016, the site provides a valuable archive of activities and technical information. DL1OFC was active across various bands and modes, including 145.225 MHz FM, 430.225 MHz FM, 29.600 MHz FM, and DMR via DB0AGM on TS-1 TG-262 DL. Shortwave operations included SSB on the 40m through 10m bands, as well as 6m. The site details regional amateur radio activities in and around Hankensbüttel, offering a glimpse into local field days and community involvement. A notable feature is Die Isetalrunde, a regional amateur radio net covering the area from the Harz mountains to the sea. The site also includes general information on radio technology, tips for obtaining an amateur radio license, and discussions on VHF/HF propagation, including specifics on the 70 MHz band.

A rotary dipole antenna for 30 meters band. Each arm is about 12.5 ft and is constructed from telescoping fibreglass flag/fishing poles and short lengths of aluminium tubing. Two short lengths of glass-fibre rod were used to insulate the arms from the supporting hardware.

Homemade receiver for 80 meters band. The receiver works very well (in fact better than some of its successors), especially the AGC makes listening to 80m QSOs a real pleasure. Sensitivity is not cutting-edge, but on a full-size short-wave antenna it is by fare sensitive enough.
