This map shows real-time radio propagation from stations operating on 11 bands between 1.8 and 54 MHz in the amateur radio service. The display shows world-wide activity from the last 15 minutes and is automatically updated about every minute. Data for the map is gathered from several online sources: WSPRnet, Reverse Beacon Network (CW, FT4, FT8), PskReporter, and DX Cluster.
Schemaric diagram for a 80m, 40m, 30m, 20m EFHW Antenna Antenna Tuner. The tuner has been designed for an antenna length of 41m and the counterpoise 7.5m.
Maybe not state-of-the-art technology but the author offers a quick and easy project for a Morse code practice oscillator using a 555 timer chip
Online DX Cluster provided by URE Union Radioafocionados Espanoles Provide current band status, propagation map, solar indices and dx spots with several filtering functions
The MSF radio signal is a dedicated standard-frequency and time broadcast that provides an accurate and reliable source of UK civil time. It is available 24 hours a day across the whole of the UK and beyond. The signal operates on a frequency of 60 kHz and carries a time and date code that can be received and decoded by a wide range of readily-available radio-controlled clocks.
In this project, we blend old school and new school tech to create a Morse code oscillator that you can use to practice keying Morse code. We start by milling out a double-sided board on the Bantam Tools Desktop PCB Milling Machine, then we solder on a series of components, and finally test our skills of yesteryear communication
This is an easy afternoon project to switch multiple cw keys between several rigs. If you’ve ever wanted to change keys on one rig or use one key on several rigs, this gadget makes it easy. Plug keys into the box inputs, and plug each of the box outputs into a rig. No need to fumble around behind the rigs to move a key from one to another or to swap paddles for a bug.
