LilacSat-2 (CAS-3H)

Uplink:144.350 MHz FM, no CTCSS/PL
Downlink:437.200 MHz FM, +/- for Doppler


The LilacSat-2 FM repeater is currently planned to be active for 24 hours at a time,starting around 2200 UTC on Mondays, Wednesdays, and Fridays. This schedule is flexible, and subject to change without prior notice.

As with other satellites, full-duplex operation is preferred. This allows you to hear your own signals from the satellite, without relying on others to confirm that. Please listen around the
144.350 MHz uplink frequency before working LilacSat-2 passes, as this is a frequency outside the normal 2m amateur satellite subband at 145.800-146.000 MHz. The 144.350 MHz uplink frequency is a legal uplink frequency per the International Radio Regulations and (in the USA) FCC Part 97, but may conflict with local or regional band plans.

Some operators have reported that receiving the LilacSat-2 downlink using narrow FM, instead of “normal” FM, may improve the downlink audio.
