From Static to Signal
or, 'Why I'm Getting into Ham Radio'

Amateur radio is an umbrella term used to refer to usage of the radio spectrum for recreational purposes. It is a diverse hobby that encompasses everything from DXing -- the challenge of contacting distant stations by bouncing signals off the ionosphere -- to space communications, where operators bounce signals off satellites or even the moon. Many modern hams also utilize digital modes, using computers to transmit data across narrow bandwidths or through high-noise environments that would be prohibitive to standard voice communication. Since radio frequency spectrum is highly regulated on the international scale, all transmitters are required to hold a license. There are strict rules governing on which bands you may transmit, what kind of data is transmittable, power limitations, and more. The licensing process ensures you're aware of such gaurdrails and their extent (even if you don't remember every edge-case). The exams also lean suprisingly hard into electrical engineering theory, which I'd guess is mostly a legacy requirement from when "off-the-shelf" gear wasn't readily available and ham's were forced to build their own stations. Luckily, most of the technical knowledge was familiar from my undergraduate degree.

There are three tiers of licenses -- Technician, General, and Amateur Extra -- each of which unlock new portions of the amateur spectrum. I ended up taking all three exams in one sitting, partially because the testing fee is only charged per session, but mostly to stroke my own ego.

I had two motivating factors when deciding to get my Ham license. First, I've been thinking I need some non-athletic hobbies (since I cannot just excercise indefinitely) and radio is about as un-athletic as it gets. Second, I've been looking to get into some type of technical-project based hobby. As a PhD student, I love my work, but none of it is immediately practical without the backing of a large corporation. I miss the fun of building things, trying to figure out which details make them work and why. Still, I've also always found it hard to come up with "side project ideas", probably because I'd consider myself more of a 'hacker' than a 'maker'. I'm not typically interested in making useful things which solve problems, but instead in the act of tinkering itself -- the 'play' involved in constructing and exploring a system. Radio fits well with this motivation. I already have perfectly good communication equipment; my phone and laptop are more reliable than any radio I build will be. Despite this, amateur radio is an endless rabbit-hole of interesting, from the different bands with unique propegation properties to the various transmission modes to the magic of antenna design. Because amateur radio is self-contained (doesn't rely on existing infrastructure), it is a system you can feasibly understand every detail of. In a world of proprietary tech and opaque abstractions, radio offers the rare satisfaction of a system entirely transparent to the curious mind.

My first goal is to build my own transceiver and get on the air. I'm also planning to join my university's radio club and get some advice from veterans, but beyond that, who knows? I'm excited to see where this takes me!
