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. The amateur radio station on the ISS can be received using very simple equipment. Most of the astronauts on the International Space Station are licenced Radio Amateurs and sometimes during their spare time they talk to other Radio Amateurs back on earth.

NASA already provides this space-to-ground communication with commentary during space shuttle missions. Sorry, your blog cannot share posts by email. If adjusting for Doppler shift manually try tuning the uplink frequency while transmitting to keep the downlink frequency constant. 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. 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. Listening Online. Lower power will also work well.

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. Hamming it Up on the ISS 04.06.04 Amateur radio, also called ham radio, has become a fun way for average folks to communicate with International Space Station astronauts. Please use a maximium uplink power of 5 watts to a 7 dBi gain antenna (25 w EIRP). Hand-held rigs all seem to have a single wide filter fitted as standard. Transponder is only active during night passes and at weekends Almost any 144 MHz FM rig will receive the ISS, you can even use a general coverage VHF scanner with an external antenna.

The group produce a quarterly publication OSCAR News that is full of information on the Amateur satellites. Astronaut Sunita Williams KD5PLB on the ISS. You can check the current mode of operation on the AMSAT Satellite Status page. Commander William Shepherd, KD5GS, made the first Amateur contacts in November of that year. • R4UAB WebSDR when ISS is over Russia http://websdr.r4uab.ru/ There are a number of websites that tell you when to listen such as the N2YO site. The streaming station and shuttle mission audio is available on the following NASA sites: This means you need to make sure you’re listening at the right time to hear it.
Radio Communications Subsystem 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”. 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. NASA - National Aeronautics and Space Administration, Image to right: Logo image for the Amateur Radio On The International Space Station program. Select a Frequency of 145800.0 kHz and Mode FM: The International Space Station is traveling around the Earth at over 28,000 km/h. The ISS amateur radio station is used for school contacts. Passband may be up to 15 kHz higher depending on on-board temperatures Educational Telemetry beacon is 300 mW during day and 30 mW at night. As far as the antenna is concerned the simpler the better.

There is a special thrill in talking to an astronaut out in space! To unsubscribe from this mailing list, send a blank e-mail message to hqnews-unsubscribe@mediaservices.nasa.gov. NASA already provides this space-to-ground communication with commentary during space shuttle missions. 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. • Listen to the ISS when it is in range of London with the SUWS WebSDR http://farnham-sdr.com/ • Inverting SSB/CW transponder 300 mW PEP Select a Frequency of 145800.0 kHz and Mode FM: • Farnham WebSDR when ISS is in range of London http://farnham-sdr.com/ • R4UAB WebSDR when ISS is over Russia http:// websdr.r4uab.ru / Voice and SSTV transmissions take place on 145.800 MHz FM, the AX.25 packet may be heard on 145.825 MHz FM.

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. If you know your browser is up to date, you should check to ensure that Anyone with a scanner can listen to the communications that take place between Earth and space, and if you have a transmitter, you can take part in the conversations. The Amateur Satellite organisation in this country is AMSAT-UK. HOUSTON - Conversations between astronauts aboard the International Space Station and flight controllers on the ground now are available for the public to hear live, 24 hours a day, seven days a week on NASA's Web site, www.nasa.gov . 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. These educational contacts enable students to communicate directly via Amateur Radio with the Astronauts and ask them questions. • 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.

The streaming audio of space-to-ground communications includes NASA commentary during specific station mission events and regularly scheduled space station commentary on NASA Television Monday through Friday at 10 a.m. Central time. You should never transmit on 145.800 MHz. The aim to start with is simply to listen to the sounds from the satellite. A ¼ wave ground plane has a high angle of radiation and works well. Satellite Tracking https://amsat-uk.org/beginners/satellite-tracking/, N2YO tracking site (click Draw Footprint) https://n2yo.com/?s=25544&df=1, You can use online radios to receive signals from the International Space Station: It can act as an AX.25 APRS Packet Repeater, voice repeater or transmit Slow Scan Television (SSTV) pictures. 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. What equipment do you need to hear the ISS ? The streaming audio of space-to-ground communications includes NASA commentary during specific station mission events and regularly scheduled space station commentary on NASA Television Monday through Friday at 10 a.m. Central time. Event runs from 00:00 GMT Saturday 1 August This high speed makes radio signals appear to shift in frequency, a phenomenon called Doppler Shift.
