Conditions of the Licence

Annexure I to the 1978 Rules is thirteen conditions long and carries more marks in Section B than any other single document. It is also the part of the law you actually live inside: what your station may be used for, who you may talk to, what you may say, how clean your signal must be, and the exact words you use to call, to hand over and to sign off. The 2024 Rules carry the same conditions forward in their Annexure A with very little changed, so unlike the fees and ages in the previous lesson, almost everything here is both what the examiner wants and what is true today. Work through it in its own order; the paper tends to follow it.

I. Use of the station

This is the definition of the amateur service restated as a condition, and it is the root of everything below. Without pecuniary interest is wider than “unpaid”: it bars anything from which you or the other party derive a commercial benefit, so passing a shopkeeper’s stock enquiry is out whether or not a rupee changes hands. Note too that a club station is more tightly limited than an individual’s — technical investigation and training only.

The station may also be used to receive the Standard Frequency Service, so that you can check you are inside your band. And condition I(3) forbids you to assign, under-let or otherwise dispose of the licence, or to admit any person to participate in its benefits. The licence is personal: you cannot lend your station to an unlicensed friend and call it his.

II. Messages — whom, and what

Whom you may work

Radio communications may be exchanged with other stations similarly authorised — that is, with other licensed amateur stations, anywhere. A commercial, military or broadcasting station is never a valid contact. There is one geographical bar, and the exam likes it: you are forbidden to communicate with amateur stations of countries whose administrations have notified the International Telecommunication Union of their objection to such radio communications. It is the objecting administration’s notification to the ITU that closes the door, not your own government’s opinion of them.

What you may say

Three filters, all of which must pass. Plain language rules out private codes and ciphers — the published Q codes and operating abbreviations are fine precisely because their meanings are public. Directly concerned keeps the traffic yours and your correspondent’s. And the last clause is the one candidates miss: the remarks must be unimportant enough that using the telephone would not have been justified. An amateur station is not a cheap substitute for a real telecommunication service. One narrow technical permission sits alongside: special recordings of a sinusoidal tone or tones in the audio range, constant or steadily changing in frequency, may be transmitted — test tones are equipment, not entertainment.

What you may not say

The last line surprises newcomers. Handing on a message for somebody else is ordinarily forbidden outright, and it follows from the personal aim of the service: your licence is for your communication, not for carrying other people’s. What is permitted is a description of the aerial experiment you carried out that afternoon, a signal report, the weather at your end, and remarks of that unimportant personal kind.

The one third-party exception

Condition II(3) lifts the third-party bar in exactly one situation, and every limb of it must be satisfied at once. Learn all four.

Read gate 3 carefully; it is where most candidates lose the mark. It is not enough that the telephones are down and a cyclone has come ashore. The traffic must originate from and be addressed to a competent civil authority, namely a District Magistrate, Deputy Commissioner or Collector of the district, or any other officer authorised by them. A message that starts or ends with a private individual, a relief agency or a club official falls outside the exception however genuine the distress: in an emergency the Indian amateur is a link between officials, not a public message service. Gate 4 then makes the exception self-reporting — a letter to the licensing authority on each such occasion.

III and IV. Frequencies, emissions, power and measurement

Condition III is short: the station shall be operated on frequencies within the bands authorised to its category of licence, and on such classes of emission and power not exceeding those specified. The table itself lives in Your Bands, Your Power, Your Emissions.

Condition IV puts teeth in it. The transmitter must be tuned as accurately as possible so that no energy is radiated on any frequency outside the authorised bands, and the licensee must keep at the station a reliable frequency measuring equipment and use it each time the frequency of the transmitter is changed, and whenever else a check is needed. Keeping that instrument itself accurate is also your duty. This is the condition that makes Measuring Frequency an examinable topic rather than a hobbyist’s interest: your licence requires the instrument.

V. Non-interference and a clean signal

The station must be designed, constructed, erected, maintained and worked so as not to cause interference with any wireless telegraph service inside or outside India, or with the signalling of the Indian land, naval or air forces. Two duties follow. First, before you transmit at all, you must take precautions to ensure your emission will not interfere with transmissions already in progress; if it is likely to, you do not start until there is an appropriate break. Listening first is a legal requirement, not merely good manners. Second, if your station is causing interference you must discontinue or restrict transmissions, pending adjustment of the equipment, on request from the Central Government or any land station — not on the request of any amateur who complains on the air, though courtesy usually settles those anyway.

The rest of condition V is about signal quality. The licensee shall deploy all necessary means to ensure the radiated frequency is free from harmonics, key clicks, hum and other forms of spurious emissions; shall ensure the transmitter is not over modulated; and — flatly — the use of class B emissions (damped waves) is forbidden. A damped wave is the output of a spark transmitter, a decaying oscillation that smears energy across an enormous bandwidth. The ban is absolute: not limited by band, by grade or by duration.

VII. The apparatus itself

• The station shall be equipped for reception as well as transmission — a transmit-only station is not a lawful amateur station. The exception is the Short Wave Listener’s licence, which is receive-only.
• The apparatus and accessories shall be arranged so as not to endanger the safety of the licensee or of other persons.
• It shall be kept in a safe condition and housed so as to preclude access to unauthorised persons. A rig anyone can key is a rig you remain answerable for.
• The transmitter shall be of a type having frequency stability comparable to that of crystal control.
• Meters of standard accuracy shall be installed to measure the DC power input to the anode circuit of the final radio frequency stage. That is why the Indian power limits are input figures rather than output ones.
• The aerial shall be erected, fixed or placed so as not to cross above, or fall on to, any power, telegraph or telephone line.

The aerial rule has a companion in condition XII: the licensee shall indemnify the Central Government against all actions, claims and demands in respect of any injury arising from any act licensed or permitted by the licence. If your mast comes down on a neighbour, the claim is yours to answer. The licence grants you permission to operate; it is not the Government’s liability cover.

VIII. Secrecy of correspondence

If a message you are not entitled to receive nevertheless reaches you, you shall not make known, or allow to be made known, its contents, its origin or destination, its existence or the fact of its receipt to any person — and shall not reproduce it in writing, copy it, or make any use of it. The prohibition reaches further than the words of the message: the mere fact that you heard it is covered. The only permitted disclosure is to a duly authorised officer of the Central Government or to a competent legal tribunal.

IX. Procedure on the air

Identification

Ten minutes is a hard limit inside a single period of transmission, not a guideline. If you have been talking for fourteen minutes without sending your call sign you have breached this condition, even though you identified correctly at the start. The same paragraph adds that prolonged calls and transmissions shall be avoided, and that when you need to spell out a call sign, a difficult word, an abbreviation or a figure, you use the phonetic alphabet and figure code of the Convention — drill those at the phonetics trainer.

Calling and replying

For a general call, CQ replaces the called station’s call sign in that same structure. A reply to a call is the mirror image: the caller’s call sign up to three times, DE or “This is”, then your own up to three times.

If nobody answers, the timing rule bites: the call may be sent three times at intervals of two minutes; thereafter it shall not be repeated until an interval of 10 minutes, during which the operator shall listen on the frequency band in which the call was made. The silence stops a fruitless call from occupying a frequency, and the listening makes sure you notice if the other station comes back or if the channel is now in use.

Keep AR and VA apart, because the paper pairs them deliberately. AR, or “Over”, ends the transmission of a message and invites a reply. VA, or “OUT”, ends the work between the two stations altogether, and each station sends it. “Over and out”, beloved of films, therefore contradicts itself.

Tests

Test signals for adjusting a transmitter or a receiver, or for any experiment, shall not continue for more than 30 seconds. They shall consist of a series of VVV followed by the call sign of the station emitting them in radiotelegraphy; in radiotelephony the VVV is replaced by the figures 1, 2, 3, 4… spoken in the figure code, still followed by your call sign — an unidentified test is an unidentified transmission. For tests exceeding 30 seconds an artificial aerial — a dummy load — shall be used, so the energy goes into a resistor instead of on to the band. And separately: emission of a carrier wave is forbidden unless it is subjected to intelligible modulation. Whistling a steady unmodulated carrier while you tune up is not a lawful option in India.
