ISS Cross Band FM Repeater Activated

At 01:02 GMT on September 2 a cross band FM amateur radio repeater with a downlink on 437.800 MHz was activated on the International Space Station.

The Amateur Radio on the International Space Station (ARISS) announcement reads:

The ARISS team is pleased to announce that set up and installation of the first element of our next generation radio system was completed and amateur radio operations with it are now underway. This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on July 26, 2000.

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. System activation was first observed at 01:02 UTC on September 2. Special operations will continue to be announced.

The IORS was launched from Kennedy Space Center on March 6, 2020 on board the SpaceX CRS-20 resupply mission. It consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS developed multi-voltage power supply and interconnecting cables. The design, development, fabrication, testing, and launch of the first IORS was an incredible five-year engineering achievement accomplished by the ARISS hardware volunteer team. It will enable new, exciting capabilities for ham radio operators, students, and the general public. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system.

A second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. This second system enables dual, simultaneous operations, (e.g. voice repeater and APRS packet), providing diverse opportunities for radio amateurs. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure.

Next-gen development efforts continue. For the IORS, parts are being procured and a total of ten systems are being fabricated to support flight, additional flight spares, ground testing and astronaut training. Follow-on next generation radio system elements include an L-band repeater uplink capability, currently in development, and a flight Raspberry-Pi, dubbed “ARISS-Pi,” that is just beginning the design phase. The ARISS-Pi promises operations autonomy and enhanced SSTV operations.

ARISS is run almost entirely by volunteers, and with the help of generous contributions from ARISS sponsors and individuals. Donations to the ARISS program for next generation hardware developments, operations, education, and administration are welcome — please go to https://www.ariss.org/donate.html to contribute to these efforts.

Additional Linking for VE3RWN Repeater

Linking Update:

Daily, between 6am and 9pm the 145.150 repeater will be linked to:

VE3TJU Picton
VE3QAR Belleville
VE3KFR Campbellford

You will hear the morning net at 10am daily, and the Tuesday evening Bay To Bridges Net at 7:30pm.

This is intended to provide wide-area Hwy 401 coverage from Oshawa through to Belleville and Picton, and to join together amateurs in Quinte and Northumberland.

VE3TJU http://www.peradioclub.ca/
VE3QAR https://www.qarc.on.ca/
VE3KFR http://tcarc.ca/

Note: The link is programmed to shut off at 9pm allowing for the evening Rag Chew to commence.

VE3OBI DMR is back online!

[UPDATED] The VE3OBI DMR is back online on 442.1375 (CC1) and my DMR page has been updated. Based on conversations so far, it seems OBI will be on the BrandMeister network and is located in the Raglan, ON area. 

Currently, there are no repeaters in the Durham area, that are on the DMR-MARC network, as the Toronto repeater has been turned off, due to jamming.

A quick update. It looks like OBI is now connected to the BrandMeister Network.

For more information on local DMR repeaters, visit my local page here.

HAM Radio Operators Still Have Role To Play

ANNE FARRIES – The people who keep communication lines open when disaster strikes are looking for new talent.

That’s amateur radio clubs, and they’re increasingly filled by people above the age of 50, who would like to prepare the following generation to help in a crisis, says Mike Johnson, emergency management co-ordinator for Cumberland County.

“We have so much technology that we rely on, and when it’s taken away, it creates a problem,” Johnson said Thursday. “There’s no question we need new blood.”

Once licensed, amateur radio operators — or HAM operators — can “set up a radio with a 12-volt battery and transmit to the world, to let them know how things are,” Johnson said.

In a crisis, if the servers that look after cellphone and landline transmission are down, “getting hold of emergency responders gets to be difficult, because people who live in, say, a 661 prefix can’t call a 667 prefix, so they can’t get through to the emergency service,” Johnson said.

So in Cumberland County, for example, “ (HAM) radio members go to the various fire departments where we’ve already arranged equipment,” Johnson said.

“We broadcast to the public: If you have an emergency, please call the local fire department. From the local fire department that information is passed on to the amateur radio member, who relays it through to a central location where the appropriate organization — ambulance, fire, police — is able to respond to the incident.”

That system was formalized in 2008, after a backhoe on the side of the Trans-Canada Highway in Amherst cut the fibre-optic cable, Johnson said.

“All digital communication east of that point to Newfoundland went down. ATMs, all 1-800 numbers, 911 — even TMR (trunk mobile radio, used by police and fire services) linking is done by Internet, so the communication between TMR towers went down.

“It was a major communication loss.”

During that incident, fire departments radioed emergency calls to a central location, where the appropriate agency was notified.

That led to amateur radio clubs agreeing to provide service to several fire stations in Cumberland County and now, “they’re deeply entrenched with us,” Johnson said.

“They have offices in here . . . with high-frequency radios for worldwide communication, as well as VHF for local communication.

“We purchase equipment, they maintain the process. So we get a lot of free work out them and they get some equipment out of us. It works out very well.”

There are about 35 people in the Westcumb Amateur Radio Club, one of 29 clubs in the Maritimes. Members share technical tips and run field days, including fox hunts, where a low-power transmitter is hidden and the person who finds it first wins a free radio.

They also help in fundraisers, such as athletic races through areas where cellphone service is not available.

“We have a very active organization here, a forward-looking group of people, and we have a great relationship with the municipality,” Johnson said.
