Handy Guide for Geolocating ‘Amateur Radio Prefixes’ | #hamr

A6CV has a nifty shorthand guide for geolocating any radio callsign. For example if someone is HL1* you’ll know they’re from the city of Seoul in South Korea; or 3ZZ* is from Poland; versus 3XZ* from Guinea; or the former Russian Federation states countries which use prefixes UAA-UIZ including a specific number of them specially reserved for WWII veterans – fascinating!

Radio callsigns for the world are set by the ITU – the UN Agency which coordinates all radio activity. The ITU allocates a block or blocks of prefixes to each country, and all callsigns must begin with the specified prefix. This applies to all radio amateurs, aircraft, ships, broadcast, commercial stations etc.

Check out the entire guide here.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
