The CB Radio spectrum is broken up into 40 channels with CB frequencies ranging from 26.965 to 27.405 MHz. Channels are generally spaced 10 MHz apart. While these channels are open to everyone, some have commonly agreed upon purposes, which are noted in the table below. Examples include Channel 9 (reserved for emergency communications) and Channel 19, which is mostly used by truckers. If you want specific information or want to share messages on these channels, you are welcome to do so or just switch over for a listen. A fair warning though: truckers have their own handles and slang, and chatty visitors are not always welcome. So be prepared and know what you’re in for if you jump on 19 as an outsider.

What is a Repeater
A radio repeater re-transmits a radio signal. In telecommunications, a repeater is an electronic device that receives a signal and re-transmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.

The X-COM Mobile RF Recording and DF/Geo-Location System (MRS/DFGS) can continuously record large segments of the RF spectrum for hours or days while simultaneously determining the direction of arrival and geo-location of emitters of interest.

Canadian Table of Frequency Allocations

Canadian Table of Frequency Allocations

The Canadian Table of Frequency Allocations (Canadian Table) assigns the electromagnetic spectrum and establishes the frequency allocations available for radio services in Canada. The Canadian Table is based on the provisions of the Final Acts resulting from the various World Radiocommunication Conferences (WRC), including the 2015 WRC, convened by the International Telecommunication Union (ITU). 
The Canadian Table and the associated general information will, from time to time, need to be revised. Such revisions occur when changes to the ITU Table of Frequency Allocations (ITU Table) are made as a result of World Radiocommunication Conferences or particular Canadian radio service requirements. The Canadian Table reflects international changes while taking into account Canadian requirements to ensure that government, commercial and private users have full flexibility to develop new radio applications and systems.
The Canadian Table is intended to respond to Canadian domestic spectrum requirements, and consequently reflects Innovation, Science and Economic Development Canada’s (ISED) spectrum allocation and utilization policies developed through public consultation. It should be noted, therefore, that the Canadian Table differs, where necessary, from the ITU Table.

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.
