HAM Lab.
HAM LAB was inaugurated by Mr. Ram Mohan, Director NIAR(National Institute of Amateur Radio), Hyderabad at Vishnu innovation labs, Department of ECE, BVRIT, Narsapur on 28thJune 2018 in the presence of Dr. I. A. Pasha, HOD, Dept of ECE, HOD’s of various departments and Dean’s, faculty and students of BVRIT.
Students have demonstrated the projects based on HAM technology. Some of the projects presented by students include satellite tracking, Fox hunting, Antenna Designing and Software Defined Radio. The guest of honor Sri.Rammohan, motivated the students to enrich their knowledge in communication technology by using amateur radio which will work under any circumstances.
The introduction of TOM made the students enthusiastic. Because of his achievements in HAM, he got a page in the 9th class academic textbook. We proudly felicitated both of the NIAR members.
ABOUT HAM:
| Amateur Radio is a popular hobby and service that brings people electronics and communication together. People use HAM Radio to talk across the town, around the world or even into space. The persons who want to become HAM they have to write HAM examination and get license from Ministry of communications and Information Technology. |
| Amateur Radio operators in their free time use their radio stations and conduct two-way communication and exchange cultural, personal, technical information with other amateurs not only within India but all over the world. The two-way communications using Radio transmitters, receivers, antennae can be either through Voice, Morse Code, Digital (Video & Data) or through Satellites. HF radios hams can talk to other hams in literally any part of the globe. |
OBJECTIVE of HAM LAB
| HAM LAB is the electronics and communication laboratory where the student can work on basic electronics circuits like transmitters and receivers, Antennas development, Satellite communication and signal, image processing etc by using HAM kits. |
WORKSHOPS:
| LIVE SATELLITE TRACKING USING HAM: 12th Dec,2017 |
| Department of Electronics and Communication Engineering, has conducted an awareness program on HAM Radio and workshop on Live Satellite Tracking Using HAM with the help of National Institute of Amateur Radio(NIAR). Mr. Rammohan, Director NIAR is the chief guest for this awareness program. |
| LIVE STELLITE TRACKING program started with 46 students. The students are divided into 6 groups. NOVA 19 is the one of the American weather satellite which is passing through our country on same day at 2:47 PM. The student groups are distributed with Ham kits and Antennas. Satellite sent the frequency in the form of audio. This audio captured in mobiles and converted into weather image by using Wxtoimg software. The satellite tracked totally for 10 mins. |
AWARENESS PROGRAMS:
| NIAR conducted awareness program in BVRIT, Narsapur on 26th Feb,2016. I,II,III,IV year students of ECE participated in the awareness program. Mr.Rammohan garu vice chairman NIAR is the chief guest for this program. |
| Students are got motivation by the activities of NIAR during disasters. Electronics and communication technology improvement through HAM is explained during the program. Total 85 students are participated. |
NIAR VISITS:
| II year and III year students of ECE, BVRITN are visited NIAR on 29th Dec 2016 along with their class teachers. NIAR team explained about Ham activities and Technology behind HAM with some practical experiments. |
| Students learned the Radio transmitters and receivers and Played FOX HUNTING Game by using HAM transmitters and Receivers. Total 54 students are participated. |
HAM EXAMINATION at BVRIT:
| Government of India Ministry of communications and Information Technology with the help of NIAR conducted a HAM examination at our college on 22nd February, 2017. Total 34 UG students from our college are appeared for this exam. |
| Twenty students are cleared this exam and they applied for License, four members got licenses and students purchased HAM kits. |
PROJECTS
| 1. SATELLITE TRACKING: |
| Students can track the satellites like Nova, this is a weather satellite which are moving around our country. By using HAM kit student can listen and save the satellite sound at a particular time. |
| Highlights of this Project: |
| Here the student can learn about different satellites. |
| They can learn about audio to image conversion algorithms.(Audio processing and image processing) |
| 2. HAM RADIO COMMUNICATION SYSTEM DESIGN: |
| Student can able Design the HAM communication system in three modes. |
| UHF- Ultra high frequency HAM radio |
| VHF- Very high frequency HAM radio |
| HF – High frequency HAM radio |
| Highlights of this Project: |
| Here the student can learn about Transmitter and Receiver designs. |
| student can learn about All Frequency and Amplitude modulations. |
| 3.ANTENNA DESIGNING: |
| In this projects students are Design the various types of antennas. Example Yagi antenna. By using these antennas students are able to increase decrease the range of the HAM radios. Many antennas have been invented simply by necessity. |
| The heart of the system of Amateur Radio is the antenna. There are many other misinformed persons stating that power is the ultimate force. Not So ! The heart of any radio station, be it Amateur Radio, Commercial, Business, CB, Personal Family Radio, or experimenters in extremely low power amateur radio ( QRP as it is called ) transmissions IS the antenna! Without good reception, you won’t hear much. Without good antennas for transmitting, you won’t transmit far, even if you apply high output RF power, or if high output watts are used ! Height, length, feedline, balun, insulators, type wire used, or type metal used, what do you want to do with this antenna, how many bands do you want it to perform its work is also important in antenna design. |
