![]() So, now, I’m eagerly awaiting delivery of the antenna, and hope to work the ISS and other satellites soon. Nearly everyone recommended the Arrow antenna over the Elk, but what really clinched the deal was that Jeff, KE9V, noted that if I purchased the Arrow antenna via the AMSAT website, AMSAT would get a cut of the sale. Not the best timing, as it’s starting to get cooler here in Michigan, but it is what it is.Īfter looking at a number of designs for homebrew antennas, and considering the Elk 2M/440L5 Dual-Band Antenna, I decided to buy an Arrow II 146/437-10WBP Handheld Yagi w/ Duplexer after consulting with the guys on Twitter. I rejoined AMSAT and ordered a satellite antenna. The ARISS-Pi promises operations autonomy and enhanced SSTV operations. 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. 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. It also provides on-orbit redundancy to ensure continuous operations in the event of an IORS component failure. voice repeater and APRS packet), providing diverse opportunities for radio amateurs. ![]() This second system enables dual, simultaneous operations, (e.g. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system.Ī second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. It will enable new, exciting capabilities for ham radio operators, students, and the general public. 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. consists of a special, space-modified JVC Kenwood D710GA transceiver, an ARISS developed multi-voltage power supply and interconnecting cables. Phase 1 of the InterOperable Radio System (IORS), was installed onboard the Columbus module in early September. ![]() Hams are already making use of the repeater. Part of the new radio system includes an FM cross band repeater system that has an uplink frequency of 145.99 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on July 26, 2000. This first element, called the InterOperable Radio System (IORS), was installed in early September in the the ISS’ Columbus module. The ham gear that was recently installed on the International Space Station is generating a lot of excitement in the amateur radio world.
