Setup Your Radio For The ISS Crossband Repeater

Programming Your Radio For The ISS Crossband Repeater

ISS (listen) 437.800 MHz cross band FM repeater activated

The new crossband repeater on the ISS has an uplink frequency of 145.990 mHz and a downlink frequency of 437.800 mHz. In order to access the crossband repeater, it requires a 67 Hz tone on your radio. Also this is an FM repeater. The best way to handle doppler is to pre-program the frequencies into your radio

Is the ISS 437.800 MHz cross band Repeater activated?

Initial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.990 MHz with an access tone [CTCSS] of 67 Hz and a downlink frequency of 437.800 MHz. 

As of September 2, 2020, the new FM Crossband repeater on board the International Space Station is activated.  The System activation was observed at 01:02 UTC on September 2. Special operations will continue to be announced. 

Ornge (formerly Ontario Air Ambulance Corporation)

Ornge (formerly Ontario Air Ambulance Corporation) is a Canadian not-for-profit corporation[2] and registered charity[1] that provides air ambulance and associated ground transportation services for the province of Ontario, under the direction of the province's Ministry of Health. The provision of ambulance services in Ontario is governed by the Ambulance Act, which states that the Minister of Health "has the duty and the power" to make sure Ontario is serviced by a "balanced and integrated system of ambulance services and communication services used in dispatching ambulances".[4] Its headquarters are in Mississauga, Ontario, Canada.

Family Radio Service (FRS) Frequencies

FCC Creates New CB on 460 MHz Band

The FCC has created a new Citizens Band service in the 460 MHz band. It's called the Family Radio Service (FRS), and is designed to be an unlicensed, "Very Short Distance Two-way Voice Radio Service." The FCC Report and Order creating the service was released May 15th, and will become effective sometime in June (30 days after publication if the Federal Register).

The specifics:

FRS will permit handheld operation, with 1/2 watt ERP and "rubber-duck" type antennas only, on 14 frequencies in and around the GMRS radio service at 462 MHz. The exact frequencies are listed below.

No external antennas or amplifiers will be permitted.

To avoid interference with GMRS stations, FRS radios will be required to use only 2.5 kHz deviation, half the usual narrow-band FM deviation of 5 kHz. Transmit audio frequency response is limited to 3.125 kHz.

Frequency stability is tight as well -- transmitters must not drift more than plus or minus about 500 Hz (.00025%). You'll find typical ham radios on UHF up to 1000 Hz off frequency.

Subaudible tone and other selective calling methods are permitted. Autopatch or other telephone interconnect is prohibited.

Antennas must be an integral part of the radio, and must be vertically polarized. (I suppose that means you can't hold the radio sideways while transmitting?)

FRS is an unlicensed service, and there are almost no restrictions on the content of FRS communications.

The FRS channel frequencies are:

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.
