Students practice using the charts and band plans.

Amateur radio log books

Station operating position with log bookStudents learn about keeping a log book of all their on-air contacts. This activity combines many other skills including call signs, RST codes, amateur radio bands and Coordinated Universal Time.

Students create an amateur radio log book and use it to log information about stations heard including their on-air contacts. SARC members submit their log books when applying for SARC award certificates like the SWL-10 Award and the QSO-10 Award for monitoring or working 10 stations.

Amateur radio operating procedures

SARC station, computer, radio and keyStudents learn about amateur radio operating procedures. Simple things like the need to listen on the frequency or channel first to see if it is clear before making a call. How to make a call and respond to a call. How to call CQ to anyone who might be listening. How to keep a log book. Things to talk about (and not to talk about) on the air. How to keep the conversation interesting. Where to look up on-line information about a station. Where to find information about on-air contests and events.

Students practice making and receiving calls using call signs and operating procedures. They enter the date, time, call signs, frequency, mode, readability, signal strength, name, location and comments into their log book.

Amateur radio operation

Radio front panel controls layoutStudents learn all about radio operation. How to set up a radio and how to adjust the controls.

Students practice tuning the radio receiver including selecting the band, frequency and mode.

Amateur radio HF communications

SARC HF communications groupStudents learn about communication on the High Frequency (shortwave) amateur bands: How radio waves propagate around the world and how the propagation changes during the day and night. They learn how to adjust the radio controls for the best reception of USB, LSB and CW transmissions.

Students practice tuning around the HF bands looking for activity. They log any stations they hear and check online databases for more information about them. They take it in turns to make contact with a station and have an on-air conversation.

Amateur radio VHF/UHF communications

VHF/UHF repeater siteStudents learn about communications on the Very High Frequency and Ultra High Frequency amateur bands: How propagation is largely limited to line of sight. How operating frequencies are channelized and how to adjust the radio controls for the best reception of FM transmissions.

Students practice tuning around the VHF/UHF bands looking for activity. They log any stations they hear and check online databases for more information about them. They take it in turns to make contact with a station and have an on-air conversation.

Amateur radio repeater communications

Repeater operation chartStudents learn about repeaters and how to use them correctly. How their transmit and receive frequencies are split. They learn that repeaters can extend line-of-sight communications to hundreds of kilometres.

Students practice tuning in repeaters looking for activity. They log any stations they hear and check online databases for more information about them. They take it in turns to make contact with a station and have an on-air conversation.

Amateur radio satellite communications

SARC satellite communications groupStudents learn about space, amateur radio satellites, orbits, antennas, latitudes and longitudes, azimuth and elevation angles.

Student practice using computer programs that show the location of orbital satellites. They can hold an antenna and manually track a satellite or they can use an antenna rotator to automatically track a satellite. Using a solar powered satellite tracking station they can listen to satellite beacons or to other stations up to several thousand kilometres away when the satellite passes overhead.
