APRS Frequencies by Country - 2026 Reference

Last reviewed: July 2026 - every row re-verified against current sources; HF dial conventions corrected, LoRa APRS added, coverage expanded to 43 countries.

If you are travelling, ordering a new radio, or moving across borders, the first practical question is always the same: what frequency does APRS run on here? There is no single global answer. The Automatic Packet Reporting System uses different VHF frequencies in different parts of the world, governed by International Amateur Radio Union (IARU) bandplans and by each country's national radio society. This guide gives you a sourced reference table, an explanation of why the frequencies differ, and the right way to confirm the local frequency before you hit PTT.

If you are new to APRS in general, start with our pillar guide: What is APRS?. If you want to see live activity on whichever frequency your country uses, the aprs.world live map shows the planet in near-real time.

Why APRS Frequencies Vary

The IARU divides the world into three administrative regions, each of which sets its own VHF/UHF bandplan:

Region 1 - Europe, Africa, Middle East, the former Soviet Union. APRS is most commonly described as operating on 144.800 MHz in Region 1 ¹.
Region 2 - the Americas. APRS is most commonly described as operating on 144.390 MHz in Region 2 ².
Region 3 - Asia and the Pacific. Region 3 has more national variation; common values include 144.390 MHz, 144.640 MHz, and 144.660 MHz ³.

Within each region, the national amateur radio society - for example ARRL in the U.S., RSGB in the U.K., DARC in Germany, TRAC in Turkey - publishes a country-specific bandplan that occasionally re-tunes APRS to a different channel for local reasons (interference, repeater spacing, harmonisation with neighbours). This is why even within Region 1 you will find a handful of countries that diverge slightly from the 144.800 MHz default.

A few things to notice. First, the 144.800 MHz "European default" is consistent across nearly every Region 1 country - that is the IARU's deliberate harmonisation effort, and it means a single radio configuration covers continental Europe end to end. Second, the 144.390 MHz "Americas default" is similarly consistent across the U.S., Canada, Mexico, and most of South America. Third, Region 3 is genuinely fragmented; if you are travelling in Asia-Pacific, do not assume - check the local bandplan.

Countries Not in the Table

We deliberately stopped at 43 rows. Many other countries have active APRS communities that we have not yet listed - India, the Philippines, Vietnam, most of the Middle East and Africa, and dozens more - but for several of them we could not find a single primary source documenting the APRS frequency in 2026. Rather than fabricate, we recommend:

Visiting your national amateur radio society's website and searching for "bandplan" or "APRS".
Asking on a local repeater or club Discord/Telegram.
Listening on 144.800 MHz (Region 1) or 144.390 MHz (Region 2/3) as a sensible first guess and tuning until you hear traffic.

HF APRS

APRS is not just VHF. The protocol works on HF too, at much lower data rates and over much longer distances - useful for ocean voyagers, polar expeditions, and anyone outside the reach of a VHF digipeater.

The workhorse HF APRS band is 30 m, and its frequency is quoted two ways that mean the same RF signal - a classic trap ¹¹ ¹²:

Legacy convention: dial 10.151 MHz LSB - the 300-baud AFSK tones sit below the dial, putting the actual signal at roughly 10.1492-10.1494 MHz, safely inside the 30 m band (10.100-10.150 MHz).
Modern equivalent: dial 10.1476 MHz USB - same signal on the air, friendlier for radios and soundcard modems that default to USB for data.
Robust Packet Radio (RPR), the modern OFDM-based HF APRS mode, runs at 10.1473 MHz USB alongside the 300-baud channel.

(Do not tune 10.151 MHz USB - that would put your tones above the dial, outside the band edge.)

Lower-band activity exists too: RPR gathers on 7.0473 MHz USB (40 m, mostly Europe) and around 14.103 MHz LSB / 14.1033 MHz RPR (20 m), though both carry far less traffic than 30 m. HF APRS uses 300-baud AFSK (or RPR) rather than VHF's 1,200-baud Bell 202 tones - slower throughput, intercontinental reach.

Bear in mind that HF amateur band edges and digital allocations vary by country far more than VHF does. Always check your national bandplan for the exact data sub-band before transmitting.

LoRa APRS

The fastest-growing corner of APRS runs not on 2 m FM at all but on LoRa - cheap ESP32 boards with LoRa radios beaconing APRS at milliwatt-to-hundred-milliwatt levels, with iGates to match. Because LoRa trades speed for sensitivity, these tiny trackers routinely cover tens of kilometres. The de-facto worldwide standard ¹³:

433.775 MHz - the main LoRa APRS channel (70 cm band), with the standard radio parameters BW 125 kHz, SF12, CR 4:5. Used across Europe and adopted in much of the rest of the world.
439.9125 MHz - the alternative channel used in the United Kingdom, where 433.775 clashes with the local band usage.
In North America, 433.775 MHz is common as well; some communities also experiment in the 902-928 MHz band. Check locally before deploying an iGate.

LoRa APRS packets enter APRS-IS through LoRa iGates exactly the way VHF packets do, so aprs.world and every other visualizer shows them side by side with classic 1200-baud stations.

Satellite and ISS APRS

The International Space Station has carried an APRS digipeater on 145.825 MHz on and off since 2007 ¹⁴. The callsign you are digipeated by depends on which onboard radio is active - RS0ISS (the Service Module station, the usual packet digipeater) or NA1SS (the Columbus module station) - not on who is aboard. The frequencies are:

Uplink (Earth → ISS): 145.825 MHz FM
Downlink (ISS → Earth): 145.825 MHz FM - same frequency both ways: a simplex digipeater, not a repeater with an offset.

When the ISS digipeater is active and the station is overhead (free pass-prediction sites such as Heavens-Above or N2YO tell you when), a 5 W handheld with a small Yagi can put a beacon into space and have it heard across an entire continent's footprint. Swap your terrestrial path for the satellite alias: WIDE1-1,WIDE2-1 becomes ARISS,WIDE2-1 - many radios let you save a separate "satellite" preset for this.

Other amateur satellites occasionally carry APRS digipeaters too - check AMSAT for currently active payloads.

How to Find Your Local Frequency

The single most reliable workflow:

Open your national amateur radio society's bandplan page. Search for "APRS" or "data".
Cross-check on aprs.fi by clicking nearby active stations and inspecting their frequency tag in the raw packet - many radios broadcast their TX frequency as part of the beacon. Paste any raw packet into our APRS Packet Decoder to see the frequency and every other field broken out.
Listen first. Tune to the candidate frequency in FM mode for two minutes. If you hear short bursts of "modem chirp" every 10-60 seconds, you are on the right channel.
Beacon at low power once - with your callsign and an appropriate APRS symbol set. Then check that you appear on the aprs.world map or aprs.fi within a minute or two. If you do, you are golden.

For travellers crossing IARU regions in a single trip - say, driving from the U.S. into Canada and back, or flying from Europe to Asia - set up two presets in your radio: one for 144.390 MHz and one for 144.800 MHz. Most modern APRS radios let you label each preset (APRS-NA and APRS-EU are popular), so swapping is a single button press.

What About Mobile Apps?

If you do not own a radio at all and are using a smartphone-only APRS workflow over the Internet - for example, the APRS World mobile app configured in "APRS-IS only" mode - frequencies do not apply to you directly. You are connecting straight to a Tier 2 server over TCP, bypassing RF entirely. The frequencies in this guide are only relevant when there is RF involved (a radio beaconing on VHF, an iGate listening on VHF, an HF link, an ISS pass).
