satellite Mode S is a fascinating mode of operation. With its2401 MHz downlink, it is leading edge technology, yet accessibleto any satellite buff willing to try it. Its popularity has beenincreasing rapidly, with new stations appearing almost daily. Thecrew up there is friendly and always eager to help new ops getstarted and swap info about what works best. It's quiet anduncrowded.
