As ARRL president, [Rick Roderick, K5UR] spends a significant amount of time proselytising the hobby. He has a standard talk about amateur radio that involves tales gleaned from his many decades ...

Amateur radio is the only hobby that offers its licensed operators the chance to legally design, build, and operate high power radio transceivers connected to unlimited antenna arrays for the ...

Amateur radio operator [KE4FOX] wanted to build his own 2M fox hunt transmitter for use at conventions. It would be contained in a 1020 Pelican micro case and attached to a person who would walk ...

The NRF24L01 is a cheap RF module that can be easily integrated into many microcontroller projects. Though there are Arduino libraries for driving the NRF24L01, [Necromat] decided to make a port ...

There used to be a time when amateur radio was a fairly static pursuit ... There is an Ethernet module and an Mbed microcontroller board on a custom PCB, which when assembled produces a few ...

For example the electronic music pioneer [Bob Moog, K2AMH], which most of you will recognise as an amateur radio callsign. Every licenced radio amateur is issued one by their country’s radio ...

For amateur radio operators, the quest for the perfect antenna never seems to end. Perhaps that’s because our requirements are always changing. We never quite seem to get to one design that can ...

The hardware is all off-the-shelf, packaged in a pretty cool 3D printed package designed to make it look like the hand held radio that it is. At its heart is the ESP32 based TTGO T-BEAM V1.0 which ...

There was a time when a ham radio set up sported many dials and switches and probably quite a few boxes as well. Computers have changed all that. Some transceivers now have just a few buttons or ...

Disappointing results perhaps, but that’s how science is supposed to work. Amateur radio often gets a bad rap, derided as a hobby for rich old dudes who just like to talk about their medical ...

In many ways we live in a much simpler world now, but in the amateur radio world one group is looking to bring this esoteric technology to the airwaves and [saveitforparts] is demonstrating one as ...

AI is currently popular, so [Chirs Lam] figured he’d stimulate some interest in amateur radio by using it to pull call signs from radio signals processed using SDR. As you’ll see, the AI did ...
