Notes from the workshop
An irregular log of projects: radio, SDR, TETRA and whatever hardware is currently spread across the bench. No fluff — what I'm building, why, and how it turned out.
AeroDock — aerial patrols with no pilot on site
SKADAR detects other people's drones. AeroDock is the flip side of the same coin — it flies your own, autonomously, straight from a hangar in the field. The drone launches itself on an alarm, streams live to the dispatcher's browser and returns to the dock to recharge. With no pilot standing in a field.
ReadSKADAR — hearing a drone before you see it
For many months our team has been building SKADAR — a passive drone detection system. There is no radar and no jammer in it: the system simply listens. A modern drone introduces itself over the air long before you can see it — you just need to know which frequencies it uses and what language it speaks.
ReadWhat's really inside AZART — and why the “indestructible” radio failed
Part two. In the first part I worked out what it costs to build an AZART equivalent. Now I take the original apart: what's inside, why a “fully Russian” radio is full of Western chips, and why a network advertised as unbreakable turned out to be jammable within months.
ReadBuild your own AZART — what hardware do you actually need?
Russia's AZART R-187P1 radio was sold as “unbreakable”. Units captured in Ukraine told a different story. I took its spec apart piece by piece and worked out exactly what hardware — and at what price — it would take to build an open equivalent, reusing what we already have in TetraPoland.
