What is a satellite repeater?
A satellite repeater for a digital satellite communication system for use on board of satellites. Receivers are provided with respective antennas for receiving radio-frequency signals from a plurality of ground stations. A signal processing circuit switches signals received in synchronism with stable clock timings.
Is AO 91 active?
At 06:50 UTC on November 23, 2017, AMSAT Engineering officially commissioned AO-91 (RadFxSat/Fox-1B). AO-91 also features the Fox-1 style FM U/v repeater with an uplink on 435.250 MHz (67.0 Hz CTCSS) and a downlink on 145.960 MHz. …
What do repeaters do to an incoming signal?
A repeater is an electronic device in a communication channel that increases the power of a signal and retransmits it, allowing it to travel further. Since it amplifies the signal, it requires a source of electric power.
How do repeaters work?
A radio repeater simultaneously receives a radio signal and re-transmits it at a higher power so it can cover greater distances. Repeaters receive radio waves on one frequency, called the “input” frequency, and then re-transmit the information on its “output” frequency.
What are AMSAT’s Satellites?
The satellites carry spectrum monitoring payloads and are currently active. At the request of the Technical University of Budapest, AMSAT hereby designates SMOG-P as Magyar-OSCAR 105 (MO-105), and ATL-1 as Magyar-OSCAR 106 (MO-106).
What new satellites are going to space in 2019?

How does the radfxsat-2 spacecraft bus work?
The RadFxSat-2 spacecraft bus is built on the Fox-1 series but features a linear transponder “upgrade” to replace the standard FM transponder in Fox-1A through D. In addition, the uplink and downlink bands are reversed from the previous Fox satellites in a Mode V/u (J) configuration using a 2 meter uplink and 70 cm downlink.
What is the best satellite guide for beginners?
A perennial favorite, Getting Started is updated every year with the latest amateur satellite information, and is the premier primer of satellite operation. The book is presented in PDF format, in full color, and covers all aspects of making your first contacts on a ham radio satellite.
