Morse key and buzzer project for Scouts
Ham Radio/Radio Scouting
This morse key and buzzer design only requires parts that one may already have or are easy to find on the web. There is nothing critical except that the contacts must meet when the key is depressed.
Spiral Dipole Antenna for 40m
Antennas/Spiral
This antenna is an off-center fed spiral dipole for 40 meters. The spiral dipole is very compact, making it well-suited for limited space (like an apartment patio), while the off-center feed gives the antenna some multiband capability.
Microvert Antenna for 40m by ON7IR
Antennas/Capacitive
A mircovert antenna assembled for the 40m version of the DL7PE antenna.
A one meter long aluminum tube with 24mm diameter is used for the base (element 1) and a 50cm aluminum tube with 20mm diameter for element 2 (the extention). A pvc pipe, 34cm long and with a diameter of 38mm, is used to wind the coil on (1mm enamelled copper wire).
A 7 elements 144MHz yagi antenna
Antennas/2M
A home made project for a 7 element yagi antenna for the two meters band based on the DK7ZB original desing.

End fed half wave antenna 40/30/20m
Antennas/End-Fed/End Fed Half Wave Antenna
For my SOTA activities, i recently bought a QRP transceiver QRP SW-3B, which is a three-band QRP CW only for 40/30/20 m.
So, i needed an antenna that would allow to use these 3 bands in SOTA portable activity.
Already having some experience with the EFHW antenna, i decided to build one for 40/30/20m.
RX Loop antenna
Antennas/Receiving
This loop antenna is intended to be connected as an antenna for receivers that do not have a built-in antenna such as an HF set or an old tube radio. This square barrel is wound on a wooden frame.
It consists of two windings that are galvanically isolated from each other, a main and a coupling winding. The diameter is about 40 cm.

Radio Scouting K2BSA
Ham Radio/Radio Scouting
Radio Scouting is the intersection of Scouting and amateur radio. As such it introduces Scouts to the fun, technology and magic of amateur radio. It does this through the power of the world’s largest Scouting event, Jamboree on the Air, with over 700,000 Scouts engaged in connecting with one another through amateur radio the third weekend of October.

Radio Scout Frequencies
Ham Radio/Radio Scouting
Information on frequencies suggested as Scout amateur radio frequencies. These were initially suggested by the World Organization of the Scout Movement and their Jamboree on the Air organizer. As with all amateur radio frequencies they are a shared resource. If someone else is already on that frequency, move up or down to find a clear frequency for calling.
