FT4 via satellite using Mac software
FT4 via LEO satellites is becoming more and more popular. With FT4, there is less need for yagi antennas and elevation control, given the (at least) 10 dB gain over SSB communication. Or, with Yagis and elevation, you can reduce power to below 1 W. However, FT4 requires accurate doppler control and a stable transceiver, especially given the fact that many sats have a 70cm uplink. The de-facto standard for doppler control is SatPC32. This is a windows only program, and not really intuitive to configure and use. However, when configured and up and running, it’s a very powerful and accurate program. Since programs suchRead More →
