Software Defined Radio Makes Waves at Prominent Illinois Hackspace Meetings

by | Sep 5, 2022 | Security System

Traditional analog radio transmitters are still commonly found inside even the most technologically advanced circuits, but that might soon change. Makers at hackspace labs across the state of Illinois have found that SDR transceivers do the job much more effectively, which is helping to reduce their reliance on legacy equipment. Unlike a conventional transceiver, these devices allow users to set frequencies programmatically. Once technicians have set a frequency, the transceiver won’t drift away regardless of how much the ambient temperature starts to change around it.

Many SDR transceivers have a tuning range that runs from 70MHz all the way up to 6GHz. This gives technicians more than enough space to run sophisticated data communications regardless of how much local traffic is in the area around them. Security researchers who need to regularly scan a wide swath of the electromagnetic spectrum will find this particularly useful since that slice contains almost every channel used by high-speed data transmissions.

Sensors and other gear that needs to periodically pass packets back and forth between a host could be outfitted with one of these small modules. Makers who work in these kinds of ad hoc labs are usually more than comfortable with doing this kind of work. Depending on the types of circuits involved, this might not even require any soldering. As a result, some experts are thinking that they’re soon going to make inroads into the education market.
