Made with love on the bench!
I’ve built a vertical antenna for 10m, 12m, 15m, 17m, and 20m. This is accomplished through a series of links which create a resonant quarter wave for each desired band.
As a ground plane, I have put down sixteen 10ft radials. These radials come out to just over two wavelengths on 20m, the lowest band of operation for this antenna.
Current chokes help a random wire antenna greatly. But how much? So much so that they allow for operation on new bands?
How well does a 29ft wire work with a 9:1 unun and an L-match tuner? Which bands are available?
The random wire antenna is among the more popular options for portable operating in ham radio. Here, I scratch build the 9:1 unun and L-match tuner within a single enclosure in order to further explore which lengths of wire are best portable random wire operating.
This basic homebrewing tool kit will allow you to build kits, experiment with antennas, and dip your toes into scratch building your own radios from schematics.
When soldering electronics, it is important that the board that you are working on doesn’t move around on you. Basically, a helping hand set helps you hold on to your soldering projects so that your other hands are free to hold the iron and the solder. At times, I have found that the basic helping […]
A key is a switch that is used for sending Morse code. When you press down on a key, it completes the circuit which sends your signal out into the world. If it is connected to a radio, that is. In the meantime, you can connect it to an oscillator (a fancy word for buzzer) […]
