AT1RS – Amateur Radio Field Day 2020

Over the Republic Day weekend of 2020, the hams of Kozhikode took their radios to the sand at Kappad Beach for a two-day amateur radio field day — and put a rare special callsign, AT1RS, on the air to honour the 250th session of the Rajya Sabha and 70 years of the Indian Constitution.

Amateur Radio Field Day at Kappad

For two days the hams set up their stations on the open beach and worked the bands from a temporary site — a hands-on rehearsal of emergency operating.

Why AT1RS

250th session of the Rajya Sabha

The Rajya Sabha, or Council of States, is the upper house of India's Parliament. It can have up to 250 members — 238 representing the States and Union territories and 12 nominated by the President.

It is a permanent house that is never dissolved; instead, a third of its members retire every two years. Its 250th session in 2019 was the milestone the callsign celebrated.

70 years of the Indian Constitution

India's Constitution was framed by the Constituent Assembly, with its Drafting Committee chaired by Dr B.R. Ambedkar. It came into force on 26 January 1950 — the day the country marks as Republic Day — so AT1RS went on air over Republic Day weekend, 70 years on.

What is an amateur radio field day?

A field day takes amateur radio out of the shack. Operators put up antennas and complete stations in the open — at Kappad, right on the beach — power them from portable sources, and try to make as many contacts as they can.

It is part friendly contest and part rehearsal. Working from a temporary site is exactly what hams do when floods or storms take normal communication down, and a public setting lets anyone curious walk up and see how it works.

  1. Set up in the openAntennas, radios and power assembled from scratch on site.
  2. Work the bandsContact as many stations as possible, near and far.
  3. Practise for emergenciesBuild the skills that matter when other networks fail.
