The IORS replaces the Ericsson radio system and packet module that were originally certified for spaceflight on 26th July 2000. Astronaut Peggy Whitson, Expedition 5 Flight Engineer, holds one of the Amateur Radio antennas prior to installation on the ISS. System activation was first observed at 01:02 UTC on September 2. System activation was first observed at 01:02 UTC on September 2. Initial operation of the new radio system is in FM cross-band repeater mode using an uplink frequency of 145.990 MHz with a CTCSS access tone of 67 Hz and a downlink frequency of 437.800 MHz. Your channel receive setting will be 437.800 MHz. The ARISS team is pleased to announce that setup and installation of the first element of our next-generation radio system were completed and amateur radio operations with it are now underway.

The initial operation of the new radio system is in FM cross-band repeater mode using an uplink frequency of 145.99 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. Supports 32-bit and 64-bit ARM architectures (i.e., armeabi-v7a and arm64-v8a). Colin Butler is a podcaster, journalist, blogger and IT industry professional with over 15 years of IT experience. Special operations will continue to be announced. Capabilities include a higher power radio, voice repeater, digital packet radio (APRS) capabilities and a Kenwood VC-H1 slow scan television (SSTV) system. The new crossband repeater on the ISS has an uplink frequency of 145.990 mHz and a downlink frequency of 437.800 mHz. voice repeater and APRS packet), providing diverse opportunities for radio amateurs. Special operations will continue to be announced. Thank you for subscribing to the ICQ Amateur/Ham Radio Podcast e-Newsletter! In this case, the receiver on the ISS listens for messages on 145.990, then repeats that message on … If I had a 2.5 kHz tuning step on my radio, I would have used that and started talking on 145.9875 MHz before moving up to 145.990 MHz. This Doppler shift will cause the ISS transmit frequency of 145.800 MHz to look as if it is 3.5 kHz higher in frequency, 145.8035, when ISS is approaching your location. ISS crossband repeater geactiveerd Published: 03 September 2020 Kijk, weer een nieuwe mogelijkheid om verbindingen te maken: contacten leggen via het International Space Station (ISS) door gebruik te maken van de nieuwe crossband repeater die sinds kort is ingeschakeld. System activation was first observed at 01:02 UTC on September 2. ARISS–Celebrating 20 years of continuous amateur radio operations on the ISS! The ARISS-Pi promises operations autonomy and enhanced SSTV operations. APRSdroid is an Android application for Amateur Radio operators. 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 Statio. Keep your fingers crossed. Your channel transmit setting will be 145.990 MHz with the 67 Hz encode tone. The downlink being 170 kHz above the downlink frequency is closer than what we see with SO-50's 70cm downlink. More. Sinds 2 september is de FM-repeater van 2 m naar 70 cm ook al actief. 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. ISS Voice Cross-band downlink. In order to access the crossband repeater, … It is a specially modified Kenwood D710-GA VHF/UHF transceiver. -----Original Message----- From: owner-AMSAT-BB@AMSAT.Org [mailto:owner-AMSAT-BB@AMSAT.Org] On Behalf Of Luc Leblanc (VE2DWE) Sent: August 31, 2004 11:34 AM To: Amsat-bb@AMSAT.Org Subject: [amsat-bb] Re: [sarex] ISS repeater 1237 UTC report On 31 Aug 2004 at 5:54, Kenneth, N5VHO wrote: > The cross band repeater operation aboard the ISS … I wonder if the testing will include reversing the uplink and downlink bands, since in the past the ISS cross-band repeater normally operated with a 70cm uplink and 2m downlink. System activation was first observed at 01:02 UTC on 2nd September. It will enable new, exciting capabilities for ham radio operators, students, and the general public. 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. In this mode, the mobile rig is configured as a one-way simplex repeater, receiving a 70cm simplex signal and retransmitting it out on the CCAR 2-meter repeater’s input frequency. Supports popular... Read more, What is APRSdroid? A second IORS undergoes flight certification and will be launched later for installation in the Russian Service module. De installatie van het eerste element van de nieuwste generatie radiosystemen is klaar en operationeel. De ISS 437.800 MHz cross-band-repeater is geactiveerd, zo meldt ARISS. Your transceiver will need to support Cross Band operations. ARISS is run almost entirely by volunteers and with the help of generous contributions from ARISS sponsors and individuals. We may get more opportunities to use the cross-band repeater in the near future. The CX-AUTO... Read more, VA3NCD had the luxury of being able to install 2 50MHz 7el Yagis for testing one against the other. 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. This first element, dubbed the InterOperable Radio System (IORS), was installed in the International Space Station Columbus module. This second system enables dual, simultaneous operations, (e.g. Initial operation of the new radio system is in FM cross band repeater mode using an uplink frequency of 145.99 MHz with an access tone of 67 Hz and a downlink frequency of 437.800 MHz. Downlink 145.800; Uplink 145.200; FM VOICE for ITU Region 2&3: North and South America-Caribbean-Greenland-Australia-South Asia. Also known as One-Way Cross Band Repeat, the range extender mode can be used when an HT has insufficient transmit power to bring up the CCAR repeater during an activation or public service event. With all of that said, it has been fun to have the cross-band repeater to use - both in V/U and (previously) U/V modes. 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. The IORS was launched from Kennedy Space Center on 6th March 2020 onboard the SpaceX CRS-20 resupply mission. This way two stations a long distance from each other can communicate beyond their normal range.
