How to Call Space Station Astronauts on the Radio

A ground station contains a device capable of both transmitting and receiving radio waves near the 145 megahertz frequency. The ISS radio transmits signals at 145.80 MHz and receives signals at either 144.49 or 145.20 MHz, depending on its orbital location.

Some ISS crew members make random, unscheduled, amateur radio voice contacts with earth-bound radio amateurs, often called "hams". They can make radio contacts during their breaks, pre-sleep time and before and after mealtime. Astronauts have contacted thousands of hams around the world. The work schedules of the ISS crew dictate when they are able to operate the radios. The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well.  (The current crew work schedule is published on the NASA website.)

Want to talk to an astronaut in space? Thanks to the Amateur Radio on the International Space Station (ARISS) program, you may be able to. There's a ham radio on board the space station, and about 45 times a year, crew members tune in and hold Q&A sessions with groups of people (usually students) from around the world.

Proper Phonetics!
I have a pet peeve. I wish that amateurs would always use the accepted ITU approved phonetic alphabet when phonetics are used. Hams in all countries generally understand the International Telecommunication Union (ITU) phonetic alphabet. It is used when signing your call or passing information that must be spelled out.

Hams use three-letter Q signals on every mode and even in face-to-face conversation. Here are the Q signals most commonly used in day-to-day operation. Each signal can be a question or an answer, as shown in the Meaning column. A complete list of ham radio Q signals.

Q SignalMeaning
QRLIs the frequency busy?
The frequency is busy. Please do not interfere.
QRMAbbreviation for interference from other signals.
QRNAbbreviation for interference from natural or human-made
QROShall I increase power?
Increase power.



Would you be ready if a call came from your local public service group to provide some ham radio expertise for a day or so?

Radio Amateurs of Canada bandplanning committees coordinate the development of National Band Plans to provide guidance for the usage of the Canadian Amateur bands.  These committees are made up of representatives from all regions of Canada.

The committees prepare interim band plans after consulting with Amateurs across the country. These plans not only take into account the wishes of Canadian Amateurs, but are also coordinated with band usage in other countries through membership in the International Amateur Radio Union. Final versions of the band plans are published in The Canadian Amateur for last minute input and are then submitted to the RAC Board of Directors for approval.

Police radio to go silent as Toronto cops move toward encrypted

They make their living listening to the night.

Screams echo from an apartment. A car smashes into a bus. A man is discovered without vital signs. Another is robbed at gunpoint.

“Any time you hear something about a gun, you take note because it could escalate,” Victor Biro says from the cab of an SUV littered with coffee cups, camera equipment, radios and clothes.

“And if someone is found with no vital signs, you always wait to hear if it’s a murder.”

Biro is a freelance photojournalist, and one of the last of his kind. After the city’s staff photographers have gone to bed, you’ll find Biro in his truck, listening to police, fire and EMS communications on radio scanners so he can chase the news as it happens.
