The Radio Amateur Society of Thailand (RAST) has announced that
JAISAT-1 is scheduled for launch on July 5, 2019 by a Soyuz 2.1

meteorology satellite along with a total of 34 satellites from
twelve countries.
The telemetry downlink is 435.325 MHz and the telemetry format is
4k8 GMSK Mobitex (CMX990 Mobitex format). The telemetry format is
