Question: When was the Indian Prime minister who was also an amateur radio operator (VU2RG) born?
Context: An amateur radio contact, more commonly referred to as simply a "contact", is an exchange of information between two amateur radio stations.  The exchange usually consists of an initial call, a response by another amateur radio operator at an amateur radio station, and possibly a signal report.  A contact is often referred to by the Q code QSO.  It is often limited to just a minimal exchange of such station IDs.  Stations who have made a contact are said to have "worked" each other.  An operator may also say that he has "worked" a certain country.  Amateurs use the slang expression "ragchew" or "ragchewing" to refer to an extended, informal conversation, a variation of the common idioms "chewing the fat" and "chewing the rag".  Sometimes, a contact in person, between two ham radio operators, is humorously referred to as an "eyeball QSO". In the United States, amateur radio licensing is governed by the Federal Communications Commission (FCC) under strict federal regulations.  Licenses to operate amateur stations for personal use are granted to individuals of any age once they demonstrate an understanding of both pertinent FCC regulations and knowledge of radio station operation and safety considerations.  Applicants as young as five years old have passed examinations and were granted licenses.  December 2012 marked one hundred years of amateur radio operator and station licensing by the United States government. "Ham radio" is a popular term for amateur radio, derived from "ham" as an informal name for an amateur radio operator.  The use first appeared in the United States during the opening decade of the 20th century—for example, in 1909, Robert A. Morton reported overhearing an amateur radio transmission which included the comment: "Say, do you know the fellow who is putting up a new station out your way?  I think he is a ham."  However, the term did not gain widespread usage in the United States until around 1920, after which it slowly spread to other English-speaking countries. An amateur radio operating award is earned by an amateur radio operator for establishing two-way communication (or "working") with other amateur radio stations. Awards are sponsored by national amateur radio societies, radio enthusiast magazines, or amateur radio clubs, and aim to promote activity on the amateur radio bands.  Each award has its own set of rules and fees.  Some awards require the amateur radio operator to have contacted other stations in a certain number of countries, Maidenhead grid locators, or counties.  Because amateur radio operators are fobidden by regulation to accept financial compensation for their on-air activity, award recipients generally only receive a certificate, wooden plaque, or a small trophy as recognition of their award. Q15X25 is a communications protocol for sending data over a radio link.  It was designed by amateur radio operator Pawel Jalocha, SP9VRC, to be an open communications standard.  Like all amateur radio communications modes, this protocol uses open transmissions which can be received and decoded by anyone with similar equipment.  Q15X25 is a form of packet radio.  It can be used to interconnect local VHF AX.25 packet networks over transcontinental distances.  Anyone can design or adapt the open-source software to develop their own Q15X25 system. Amateur radio or ham radio is practised by more than 16,000 licensed users in India.  The first amateur radio operator was licensed in 1921, and by the mid-1930s, there were around 20 amateur radio operators in India.  Amateur radio operators played an important part in the Indian independence movement with the establishment of illegal pro-independence radio stations in the 1940s.  The three decades after India's independence saw only slow growth in the numbers of operators until the then Prime Minister of India and amateur radio operator, Rajiv Gandhi (VU2RG), waived the import duty on wireless equipment in 1984.  Since then, numbers have picked up, and as of 2007 , there were more than 16,000 operators in the country.  Amateur radio operators have played a vital role during disasters and national emergencies such as earthquakes, tsunamis, cyclones, floods, and bomb blasts, by providing voluntary emergency communications in the affected areas. A DOS application written by Sheldon Shallon (W6EL), Miniprop is used to predict the probability of a high frequency (HF) radio signal path between two points on the Earth's surface.  For example, if an amateur radio operator or a shipboard marine radio operator with an HF radio wanted to estimate which frequencies might reach a shore-based station, she could enter data into the program.  The software would estimate the best frequencies for the operator to use based on mathematical models. An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service.  Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation.  As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication.  There are about three million amateur radio operators worldwide. Rajiv Ratna Gandhi ( ; 20 August 1944 – 21 May 1991) was the 6th Prime Minister of India, serving from 1984 to 1989.  He took office after the 1984 assassination of his mother, Prime Minister Indira Gandhi, to become the youngest Indian Prime Minister at the age of 40. An amateur radio station is a radio station designed to provide radiocommunications in the amateur radio service for an amateur radio operator.  Radio amateurs build and operate several types of amateur radio stations, including fixed ground stations, mobile stations, space stations, and temporary field stations.  A slang term often used for an amateur station's location is the shack, named after the small enclosures added to the upperworks of naval ships to hold early radio equipment and batteries.
