Is AO 85 active?
Status. Since December 2018, AO-85 has suffered from dangerously low battery voltage while in eclipse. As a result, AMSAT have disabled all on board transmitters in an effort to extend the usable life of the satellite. Transmitters are periodically turned back on to collect telemetry data.
What frequencies do satellites use?
C-band (4–8 GHz) Primarily used for satellite communications, for full-time satellite TV networks or raw satellite feeds.
Is AO 27 active?
The AO-27 FM satellite is back on the air! AO-27 is an FM V/U Mode satellite that was launched back in 1993. The satellite’s Amateur Radio payload became inoperative about 7 years ago due to an internal communications failure.
Does 64 satellite have frequency?

What frequency is the ISS on?
145.80 MHz
A ground station contains a device capable of both transmitting and receiving radio waves near the 145 megahertz frequency. The ISS radio transmits signals at 145.80 MHz and receives signals at either 144.49 or 145.20 MHz, depending on its orbital location.
Is AO 92 active?
AMSAT-OSCAR 92 AO-92’s transmitter is currently off due to low battery voltage.
What is SatPC32?
SatPC32 displays the audibility-areas of one or several selected satellites within a world-map and shows the results in text-lines below the map. Wisat represents the satellite positions in real-time in list-form. Both programs update their calculations continuously in steps of one second.
What GHz is Starlink?
“The FCC’s proposed rule asks whether or not the 12 GHz band can be repurposed without causing interference with and disrupting services provided by satellites, like my Starlink Internet service. The answer to that question is clearly no,” the pre-written comment to the FCC says.
What band is Starlink using?
Starlink also uses the V band, which is the range of 40-75GHz, as well as dipping into the X band and K band, which are the ranges of 8-12GHz and 18-27GHz respectively.
How can I listen to ham satellites?
All you need is a VHF/UHF FM receiver (like a police scanner) or a VHF/UHF transceiver (like a Yaesu VX-7) and an antenna. Start by visiting Heavens-Above.com to check the orbit of the satellite you want to listen to and specify your location. Check the passes of your specific satellite or the ISS.
How many amateur radio satellites are there?
18
Currently, over 18 fully operational amateur radio satellites are in orbit. They may be designed to act as repeaters, as linear transponders, and as store and forward digital relays. Amateur radio satellites have helped advance the science of satellite communications.
What is Gpredict?
Gpredict is a real-time satellite tracking and orbit prediction application. It can track a large number of satellites and display their position and other data in lists, tables, maps, and polar plots (radar view).
What is the frequency of FM radio on a satellite?

What is the AMSAT FM transponder’s satellite status?
The FM transponder is on no set schedule. For real time updates about which mode the satellite is in, see the AMSAT Live OSCAR Satellite Status Page Satellite is in a low-inclination low earth orbit and not visible north of about 30 degrees north or south of 30 degrees south.
What are the different frequencies of the digital telemetry beacons?
