Now, there are dozens of amateur radio satellites in space, and as a Technician you can make contacts by bouncing your signals off of them. In fact, for a long time, only the downlink had an extended component, with. to operate in the so-called C band, which employs uplink/downlink frequencies of 6/4 gigahertz, or in the Ku band, in which uplink/downlink frequencies are. One for the base station to send down to the mobile, one for the mobile, to send up to the base station (it’s a communication, and thus need two ends. Extended Ku-band is not quite so symmetrical. Answer (1 of 6): In most mobile networks today, base stations and mobile devices use different frequency bands to send data to each other. This is a total of 1000 MHz for uplink and downlink combined 500 MHz each way. It only lasted a few weeks before it dropped into Earth’s atmosphere and burned up, but it secured amateur radio’s place in space. The conventional Ku-band is confined to 14.0-14.5 GHz in the uplink and 11.70-12.20 GHz in the downlink. It carried a small beacon transmitter whose purpose was to study radio propagation through the ionosphere. downlink and uplink: In satellite telecommunication, a downlink is the link from a satellite down to one or more ground stations or receivers, and an uplink is the link from a ground. Most of the amateur radio frequency bands have a satellite allocation sub-band.
#SATELLITE FREQUENCY BANDS UPLINK AND DOWNLINK LICENSE#
For example, one of the other cool things you can do with a Technician Class license is work the “birds,” otherwise known as amateur radio satellites.ĭid you know that amateur radio operators have been sending satellites into space since the early 1960s? The Orbiting Satellite Carrying Amateur Radio, or OSCAR I for short, was successfully launched into a low Earth orbit on December 12, 1961. The most popular bands for these satellites are the 144-146 and 435-438 MHz bands. KSAT Global or customers cannot change the satellite frequency for. This is fun for a while, but don’t get stuck just talking on the repeaters. band uplink (2025 2120 MHz Earth-to-Space) and S-band downlink (2200 2300 MHz. When new hams get their licenses, they generally purchase a handheld transceiver (HT) and get on the local repeaters.
