Getting Started with the FM Satellites If you can program split-frequency memories in your dual-band radio, or your dual-band radio has two VFOs, you can work an FM satellite.
The primary FM voice mode for SO-50 is workable with dualband HTs! For the normal V/U FM voice mode with these two satellites, the UPLINK frequency – where you transmit – is 145.850 MHz.
The DOWNLINK frequency – where you receive – is around 436.795 MHz.
First, you need to know when and where the satellite will be passing over your location. There are several computer programs that will tell you that. Some are free, and others are available for purchase, through the AMSAT web site http://www.amsat.org/.
Most programs are easily updated with current satellite tracking data that is available on the Internet. Using your longitude and latitude coordinates (or your grid locator – generally available from QRZ.com and many GPS receivers), you can access amateur satellite pass information – and a lot more information!
