The Sputnix site has some information for radio amateurs concerning the
SiriusSat-1/SiriusSat-2 satellites scheduled for release from the ISS on
15 August 2018.  The following is my translation of part of the following
Russian language URLs (Copyright (C) 2013-2018, SPUTNIX):


Information for Radio Amateurs

We invite all radio amateurs to take part in reception of our signals.
We have prepared a decoder program which will allow you to decode prac_
tically all types of data which will be transmitted from the satellites,
in the first place the beacons, and also a connection to the central
telemetry database db.satnogs.org and the transmission of received
packets to us and all radio amateurs (this option can be turned off).

The satellites will work on these frequencies with the following
call signs:

SiriusSat-1 Call sign RS13S Frequency 435.570 MHz
SiriusSat-2 Call sign RS14S Frequency 435.670 MHz

GMSK 4800 modulation will be used, AX.25 G3RUH standard protocol.

SPUTNIX Telemetry Viewer can be used with standard amateur radio software
typically used for satellite reception, for example, with the combination
of Orbitron/SDRSharp and with UZ7HO's SoundModem.

Telemetry Viewer is connected with the help of AGWPE or KISS TCP inter_
faces.  User settings are accessible in the file resources/config.xml.

All three cubesats are good status. It has the same reception frequency,
but it's transmitting the beacon by waiting the different amount of time.
