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.


Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
