The Amateur Radio on the International Space Station (ARISS) team is currently celebrating the silver anniversary — 25 years — of Amateur Radio operations from space. According to ARISS International Chairman Frank Bauer, KA3HDO, the crew on the International Space Station (ISS) has configured the radio to support cross-band repeater operations. They have also supported some SSTV downlinks and participated in a special test of 9600 baud packet radio operations on the simplex frequency of 145.825 MHz. After December 19, Bauer said he expects the ISS ham radio system to be on the 145.825 MHz frequency supporting 1200 baud packet. If PCSAT is configured during the week, he said double hop APRS is possible.
