RAFT satellite to use PSK-31 mode next weekNext week, we will enable the PSK-31 transponder on RAFT. This transponder is 28.120 USB MHz PSK-31 SSB uplink and 2 meters FM down. Both RAFT and ANDE (and PCSAT-1 this week) are working fine on orbit for those with a big enough OSCAR satellite array to hear the weak 2 meter downlink. PCSAT-1 is much stronger and has passes that are almost 15 minutes in length and can be worked horizon to horizon with a good beam. ANDE and RAFT are only usable above about 10 to 15 deg with a good beam for only a central 3 minutes or less. RAFT packet-to-voice mode has been enabled for the first 3 weeks and
several stations have made contact... See web page: Next week starting Tuesday 16 Jan, we will enable the RAFT The transponder will time out after 1 minute (maybe later we can extend that time depending on usage). Remember that the footprint of RAFT is an order of magnitude smaller than PCSAT-1 and so it is hard to hear except when a high pass and the duration is only a few minutes. With PCSAT-1 fully alive this week and next, we are seeing over 80 different stations (the maximum depth of the live capture page http://pcsat.aprs.org) in under 8 hours. Just today another satellite was launched onto 145.825 so now there are
5 satellites there! Bob Bruninga AMSAT-UK
