This PDF File desscribes how to homemade a multi-band end-fed trapped wire antenna resonating on the low bands of 160 80 and 40 meters. Contains trap design instructions and some construction tips. (by G0CSK)
The antenna was designed for installation in a field conditions or limited space. Antenna may be installed at a low- height mast. Antenna does not required guys and takes small room for installation. (by UA6AGW)
A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into. (by G8ODE)
Current HF band conditions online report and graphs. This site provide 24-7-365 actual ( REALTIME ) band condition information to CW QRPp, QRPe and CW / SSB Contesters interested in increasing their scores. It can also be of benefit to other Radio Amateurs to determine band condtions for Nets and casual QSO (by K5BIZ)
WSJT-X - Weak Signal Communication, by K1JT - offers specific digital protocols optimized for EME (moonbounce), meteor scatter, and ionospheric scatter, at VHF/UHF, as well as for LF, MF, and HF propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals more than 10 dB below the audible threshold. WSJT-X incorporates nearly all popular capabilities of programs WSJT and WSPR, while adding comprehensive rig control and many other features. Open-source, download latest version for Windows, Linux, Macintosh OS X. (by K1JT)
A project of a 5 Antennas Relay Switch Box, all Switches & Relays have both contacts wired in parallel to improve reliability of operation, to prevent static build up, when an antenna is not in use the feeder coax is grounded. (by EA5AVL)
The HF ham bands can be mysterious. Some work at night, some during the day. Some seem to be good for long distance contacts while some are better for nearby contacts. Even worse, they change tremendously from hour to hour and day to day. An overview on operating on HF amateur radio bands (by N0GW)
The CQ WW is the largest Amateur Radio competition in the world. The 2018 CQ World-Wide DX Contest CW is November 24-25. The goal of making as many contacts with as many different DXCC entities and CQ Zones as possible.
