From VS1 to VT1: British Empire Amateur Radio Prefixes and Their Legacy

Explore the history of British Empire amateur radio prefixes from VS1 to VT1, including Malaya’s VS2 and VS3, and why modern ham radio operators should understand this callsign heritage.

Amateur radio callsigns are more than operating identifiers. They are small fragments of political history, geography, administration, and radio regulation. A prefix printed on an old QSL card can tell us not only where a station operated, but also when that place belonged to a particular colonial system, what authority issued the licence, and how the amateur radio world understood that territory at the time.

Among the most interesting examples are the old British Empire prefixes from VS1 to VT1. Many of these callsigns are no longer issued, but they remain important to radio historians, DXers, QSL collectors, and operators who want to understand how today’s familiar prefixes evolved.

For Malaysian amateurs in particular, this history is close to home. The old VS2 and VS3 prefixes are direct predecessors of today’s 9M callsigns.

A Prefix System Shaped by Empire

During the early and middle decades of the twentieth century, the British Empire covered territories across Asia, the Middle East, Africa, the Pacific, and the Caribbean. Radio administration followed imperial and colonial structures. As a result, many territories used callsign prefixes beginning with VS or VT, allocated under British authority.

These prefixes appeared on QSL cards, station logs, DX bulletins, and award records. Today, they help us identify stations from places whose names, borders, and administrations have changed dramatically.

Some examples include:

Old Prefix	Territory at the Time	Modern Prefix / Status
VS1	Singapore and Straits Settlements	9V1
VS2	Federated Malay States	9M2
VS3	Non-Federated Malay States	9M2
VS4	Sarawak	9M8
VS5	Brunei	V8
VS6	Hong Kong	VR2
VS7	Ceylon	4S7
VS8	Bahrain Islands	A9
VS9A	Aden	7O
VS9M / VS9B	Maldive Islands	8Q
VS9O / VS9E	Trucial Oman	Today associated with A4 Oman and A6 UAE
VS9P	Perim Island	Yemen-related history
VS9S	Socotra Island	Yemen-related history
VT1	Kuwait	Later MP4K, now 9K

This list is not simply a callsign reference. It is a map of how radio followed political change.

Malaya, Sarawak, Singapore, and Brunei

For readers of hamradio.my, the most meaningful entries are naturally those connected to this region.

VS2 was used in the Federated Malay States, while VS3 represented the Non-Federated Malay States. These prefixes belong to the radio history that eventually leads to modern Malaysian callsigns under 9M2.

VS4 was used in Sarawak, now familiar to radio amateurs as part of East Malaysia, where 9M8 is used. VS1 and one use of VS8 are connected with Singapore and the Straits Settlements, today represented by 9V1. VS5 belonged to Brunei, now using V8.

These changes remind us that amateur radio in this region did not begin with the modern prefix system. It passed through colonial administration, wartime disruption, independence movements, federation, and national telecommunications development.

Every old VS QSL card from this region is therefore more than a contact confirmation. It is a document of Southeast Asian radio heritage.

The Middle East and the VS9 Series

The VS9 series is especially fascinating because it covered several territories around Arabia, the Gulf, and the Indian Ocean.

Aden used VS9A. The Maldive Islands appeared as VS9M and VS9B. Trucial Oman, before the formation of the modern United Arab Emirates, was associated with VS9O and VS9E. Other rare or historically significant locations included Kuria Muria Islands, Kamaran Island, Perim Island, Masirah Island, and Socotra Island.

To a DXer, these names are exciting because some represent rare geographic entities. To a historian, they show how amateur radio reflected imperial shipping routes, military stations, protectorates, island dependencies, and strategic outposts.

Why Modern Operators Should Care

It is easy to think of old prefixes as collector trivia. They are much more than that.

First, they help us read old QSL cards accurately. A card marked VS2 is not just “old Malaysia” in a general sense. It belongs to a specific administrative period and geographic context. The same applies to VS6 Hong Kong, VS7 Ceylon, or VT1 Kuwait.

Second, they improve DX history. Many award records, deleted entities, and historical country lists depend on understanding how prefixes changed over time. A serious DXer benefits from knowing that a modern prefix may have older predecessors.

Third, they connect amateur radio to world history. Callsigns changed because countries became independent, colonies were reorganised, territories were renamed, and international allocations were updated. The logbook becomes a quiet record of political transformation.

Finally, this history strengthens our identity as radio amateurs. We are part of a technical hobby, but also a cultural one. Our signals cross borders, and our callsigns carry the memory of those borders.

The QSL Card as Historical Evidence

Old QSL cards are among the most valuable sources for this kind of history. They often show the callsign, operator name, town, colony, equipment, frequency, mode, and postal route. Some cards include maps, flags, colonial emblems, or handwritten notes that reveal how operators understood their location at the time.

For Malaysia and neighbouring countries, these cards preserve details that may not appear in official radio documents. They show real stations, real contacts, and real operators keeping the amateur spirit alive under very different circumstances.

A VS2 or VS3 card is not merely nostalgic. It is part of the documentary record of amateur radio in Malaya.

Preserving the Prefix Trail

Modern amateur radio should not forget these prefixes. The hobby is moving quickly into SDR, digital modes, remote stations, satellites, and internet-linked systems. Yet the foundation remains the same: a callsign, a signal, and a contact between people.

Knowing the history of prefixes such as VS1 to VT1 gives today’s operators a deeper appreciation of the callsigns we use now. It reminds us that 9M, 9V, V8, VR2, 4S7, A9, 8Q, and 9K all sit on layers of earlier radio history.

For Malaysian amateurs, the story of VS2 and VS3 is part of our own inheritance. It connects the present-day 9M community with the earliest organised amateur activity in Malaya and the wider British-administered radio world.

The next time you see an old QSL card bearing a VS prefix, pause before treating it as just a collectible. That small prefix may carry a whole chapter of radio history.
