In recent years a number of UK schools have made contact with the space station thanks to volunteers from AMSAT-UK. This high speed makes radio signals appear to shift in frequency, a phenomenon called Doppler Shift. C…. Commander William Shepherd, KD5GS, made the first Amateur contacts in November of that year. The amateur radio station on the ISS can be received using very simple equipment. Its members are involved in the construction of new Amateur Radio satellites and in running the stations used for ISS school contacts and. You should never transmit on 145.800 MHz. Sorry, your blog cannot share posts by email. Hand-held rigs all seem to have a single wide filter fitted as standard. Event runs from 00:00 GMT Saturday 1 August ARISS hardware manager Lou McFadin, W5DID, is asking for help characterizing the signal from the ISS. (Note: Packet digipeater is no longer active), Astronaut Susan Helms KC7NHZ having a contact. images: We may not be able to display every image because of quality or duplication. During the 10 minute pass the frequency will move lower shifting a total of 7 kHz down to 145.7965 as the ISS goes out of range. We've placed some restrictions on the upload of - 435.150 – 435.130 MHz Uplink LSB Check the N2YO site to see when the ISS is in range https://n2yo.com/?s=25544&df=1, Much of the time the Space Station equipment operates in “automatic mode”. until 23:59 GMT Tuesday 22 September. International Space Station NA1ISS contact with GB4YOTA; Building a 70MHz quarter wave ground plane; Receiving SSTV images from the ISS – ARISS 20th Anniversary; 1/4 Wave Antenna Calculator; A long break… My first 23cm 1297MHz contact! It needs no tuner on 40m, 20m and 10m. 3. Please submit only "clean" images with no added callsigns or other text. Using this antenna to make a contact that was 250 miles away moving at 17,000 MPH is probably the best testimonial I can give:) 73 Almost any 144 MHz FM rig will receive the ISS, you can even use a general coverage VHF scanner with an external antenna. You can receive the ISS outdoors using a 144 MHz hand-held with its helical antenna but a 1/4 wave whip will give far better results. Large 144 MHz colinears are not as good because the radiation pattern is concentrated at the horizon while the ISS is above 15 degrees elevation for most of a pass. The first Amateur Radio equipment was delivered to the International Space Station (ISS) in September 2000 and an Amateur Radio station was established onboard for use by Astronauts who are licenced Radio Amateurs. Please fill in the demographic data as completely as possible. Passband may be up to 15 kHz higher depending on on-board temperatures Radio Communications Subsystem The "rubber duck" antenna on your HT as if comes from the factory actually is a poor excuse to tack the word "antenna" on! You CAN Do It! • Inverting SSB/CW transponder 300 mW PEP Talk to the ISS with just 2W? NOTES ... 1. Select a Frequency of 145800.0 kHz and Mode FM: When the astronauts put out a CQ call they also use 145.800 MHz FM but operate “split” listening for replies 600 kHz lower on 145.200 MHz. • Listen to the ISS when it is over Russia with the R4UAB WebSDR http://websdr.r4uab.ru/, Receiving ISS Slow Scan Television https://amsat-uk.org/beginners/iss-sstv/, How to work the ISS on APRS Packet Radio https://amsat-uk.org/beginners/how-to-work-the-iss-on-aprs-packet-radio/, The IZ8BLY Vox Recoder enables you to record the ISS on 145.800 MHz FM while you’re away from home http://antoninoporcino.xoom.it/VoxRecorder/, Amateur Radio on the International Space Station (ARISS) http://www.rac.ca/ariss/oindex.htm, John Heath G7HIA’s article  ‘Getting started on amateur radio satellites’ can be downloaded from https://amsat-uk.org/beginners/radcom-getting-started-on-satellites/, ARISS Amateur Radio on the International Space Station, OSCAR News, is full of Amateur Satellite information and free to members. Les antennes verticales. Most Yagi's and verticals can be homebrewed with lots of savings in money. Only gif, jpg, and png files are allowed. A ¼ wave ground plane has a high angle of radiation and works well. It is an off centre fed dipole, with 10 feet of vertical radiator. ATV is used for non-commercial experimentation, pleasure, and public service events.

It is best to work "full-duplex" - more about that throughout the site. The ISS is in a very low orbit and so is only in range 5 or 6 times each day and then only for a maximum of 10 minutes on the best orbit. The ISS amateur radio station is used for school contacts. History The first Amateur Radio equipment was delivered to the International Space Station (ISS) in September 2000 and an Amateur Radio station was established onboard for use by Astronauts who are licenced Radio Amateurs.

Ham Radio operators have enjoyed making contact with the ISS for many years. The holy grail has always been talking to ISS … To get maximum signal you ideally need a radio that tunes in 1 kHz or smaller steps to follow the shift but in practice acceptable results are obtained with the radio left on 145.800 MHz. Ham radio programs for satellite tracking category is a curation of 53 web resources on , JSatTrak - Satellite tracking program, STSPLUS, RS41 Radiosondes Tracker. You can join online via the AMSAT-UK website. Educational Telemetry beacon is 300 mW during day and 30 mW at night. He requests that you submit signal strength, AOS, LOS, antenna gain, preamp gain, estimated cable loss, and FM sensitivity ( microvolts or dBm) of your radio. It also works fine on all bands above 40m with a tuner, and even below 40m on 60m, and 80m, although the coax losses will be higher. Transponder is only active during night passes and at weekends In the UK we use narrow 2.5 kHz deviation FM but the ISS transmits using the wider 5 kHz deviation used in much of the world. You can check the current mode of operation on the AMSAT Satellite Status page. Here is my home HF antenna. Use a high gain outside antenna if at all possible. ISS SSTV project a hit ... Do NOT attempt to work Fox 1-E right now! The International Space Station is traveling around the Earth at over 28,000 km/h. webmaster.

The Amateur Satellite organisation in this country is AMSAT-UK. Most rigs can be switched been wide and narrow deviation filters so select the wider deviation. The aim to start with is simply to listen to the sounds from the satellite. If you have problems or questions you may email the As far as the antenna is concerned the simpler the better. SSTV An HT with antenna improvement can get you in to the world of FM satellites! - 145.950 – 145.970 MHz Downlink USB What equipment do you need to hear the ISS ? It can act as an AX.25 APRS Packet Repeater, voice repeater or transmit Slow Scan Television (SSTV) pictures. This means you need to make sure you’re listening at the right time to hear it.

If you are lucky and hear them calling CQ just remember to activate your rigs repeater shift to ensure you reply on the correct frequency. Your participation is very important in assuring a place for ham radio in human spaceflight! The amateur radio station on the ISS can be received using very simple equipment. The location information you submit should be latitude and longitude, please. These educational contacts enable students to communicate directly via Amateur Radio with the Astronauts and ask them questions. Use a minimum of a 3 element Yagi or try a Slim Jim style antenna. There are a number of websites that tell you when to listen such as the N2YO site. IT CAN BE DONE! If adjusting for Doppler shift manually try tuning the uplink frequency while transmitting to keep the downlink frequency constant.
