CROWN: Student-Led Radio Revolution
The Club for Radio Operations and Wireless Network (CROWN) is a student-managed club that seeks to foster the practice of amateur radio communication, radio frequency engineering, and wireless networking among students. It was formed as an attempt to leverage the significance of radio communication technology in modern engineering, emergency services, and global connectivity by serving as a center of technical education and innovative hands-on work in wireless technology.
CROWN combines theoretical knowledge with hands-on experience by allowing students to create actual radio systems, engage in ham radio communications on national and international levels, and gain insights into sophisticated communication systems.
Mission
To provide practical training, workshops, and global participation in amateur radio to impart fundamental knowledge and skills in radio communication, RF technology, and emergency response to the students.
Vision
The student ham radio club of India which trains students in telecom, space communication, emergency services, and radio-based research projects.
Amateur radio (ham radio) acts as an anchor to engineering, emergency communications, and international connectivity.
EVENTS AND ACHIEVEMENT
BeliefSat-0: A Mission by Student Voices Over the Spectrum
BeliefSat-0 is a student-built satellite developed by the passionate members of CROWN — the Club for Radio Operations and Wireless Network — at K.J. Somaiya Institute of Technology, Mumbai. This mission stands as a tribute to 100 years of Amateur Radio in India and serves the global HAM radio community with pride and purpose. Launched aboard ISRO's PSLV as part of the POEM (PSLV Orbital Experimental Module) initiative by IN-SPACe, BeliefSat-0 operates in a 350 km orbit at 9° inclination. It functions as a UHF to VHF FM voice repeater and APRS digipeater, enhancing communication capabilities for HAM radio operators worldwide.
ISS SSTV Image Decoding by Club Members
In an exciting global HAM radio initiative, members of our amateur radio club, including Supriya Bhide (VU3ZJY), successfully decoded Slow Scan Television (SSTV) images sent from the International Space Station (ISS). These images were part of the “NASA On The Air” event, commemorating 35 years of human spaceflight through the ARISS (Amateur Radio on the ISS) program.The students employed antennas, SDR receivers, and decoding software to capture and reconstruct these images transmitted from space in real-time. This endeavor required accurate satellite tracking and a strong grasp of radio operations.Both Supriya Bhide and Umesh Sir...
ARSI National Field Day & Hill Topping Contest 2025
The Crown Club participated in the ARSI National Field Day and Hill Topping Contest 2025, a 31-hour event that encourages hands-on amateur radio communication in isolated locations. This annual event encourages ham radio operators to enhance their technical and communication skills while mimicking real-world emergency circumstances. The crew employed long wire antennas for HF bands (40m, 20m, and 15m) with CW, SSB, Digital, and QRP modes to make contacts across the country. To address previous power supply issues, they used a DC to DC power boost converter.
ARSI National Field Day and Hill Topping Contest 2024
The Crown Club participated in the ARSI National Field Day and Hill Topping Contest 2024, which was held on January 27-28, 2024, under the supervision of Dr. Umesh Shinde. The event's goal was to assess amateur radio communication skills in outdoor settings, therefore teams were required to set up their own radio stations on hilltops. The team consisted of 11 people (8 undergraduate students and 3 seasoned alumni), who chose a hilltop in Satara for their operations. They entered Category A (20m and 40m HF bands) and constructed stacked half-wave dipole antennas using bamboo and insulated copper wires.
QRP DAY 2024
The Crown Club enthusiastically participated in the QRP Contest, which was conducted by the Amateur Radio Society of India. This event improved students' knowledge of low-power amateur radio (QRP) operations, antenna setup, and communication protocols, giving an invaluable hands-on learning opportunity. The event began with expert speeches by experienced ham operators such as Dr. Umesh Shinde, Chandrashekhar Kulkarni, Shrimat Kamath, and Sarla Sharma. They discussed the evolution of ham radio, antenna principles, and the role of amateur radio groups in promoting communication technologies. The 40m, 20m, 15m, and 10m bands received special attention due to their importance in worldwide communication.
ARSI Regional Meet
Following the successful ARSI regional meeting held in Chennai in early February 2023, a similar gathering was proposed for Mumbai, coordinated by the regional team which includes Jatin (VU2KWJ) and Huzefa (VU2HIT) The aim of these regional meetings is to promote awareness of ARSI’s position as the sole member society from India in IARU-Region 3 and to illustrate how contributions from individual members can enhance ARSI’s interactions with regulatory bodies like WPC and improve its status in the global amateur radio community...
CQ Mumbai
The "CQMumbai2022" Annual Amateur Radio Convention in Mumbai City was held successfully on October 9, 2022, at the K.J. Somaiya Institute of Technology and Engineering in Sion. After a two-year hiatus due to COVID-19 limitations, the event drew attendees from Mumbai and other cities, including Hyderabad...
LARC Hyderabad 2017 – Antenna Making Contest
The LARC (Lamakaan Amateur Radio Convention) that took place in Hyderabad in 2017 was a notable occasion designed to promote ingenuity and technical advancement among amateur radio enthusiasts. The convention included a variety of captivating sessions such as antenna construction competitions, technical workshops, and keynote speeches delivered by distinguished hams, making it a standout event in the Indian amateur radio scene. Two representatives from the Crown Club, Akshay Jain and Jatin Bhosale, took part in the Antenna Making Contest, where they crafted a Moxon Yagi antenna for the VHF 145 MHz.
