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 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.

Sergei Prokopiev and Oleg Artemiev.

SiriusSat-1 (SXC1-181) RS13S beacon 435.570 MHz
SiriusSat-2 (SXC1-182) RS14S beacon 435.670 MHz
Tanusha-SWSU-3 (RS-8), 437.050MHz 1k2 AFSK, FM voice

Signal Report  SiriusSat-1  SiriusSat-2  Tanusha-3  Tanusha-4

(DK3WN Blog)
On 20 Jun 2018, Tanusha-3 will be connected to one of the ARISS Service
Module antennas and will transmit from 0730-1200UTC on 437.050MHz.
These FM transmissions will include greetings from students in several
languages, including Russian, English, Spanish and Chinese.

The ARISS-Russia team plan to also retransmit these signals on the
standard ARISS 2-meter downlink, 145.800MHz using the JVC Kenwood D700
radio that is still on-board ISS. All are invited to listen to the
CubeSats from ISS on 437.050 and/or 145.800MHz.

Tunusha-3(437.050MHz FM)⇒ ISS(受信:437.050MHz FM)内蔵レピーター
  ⇒ ISS送信(145.800MHz FM)⇒ 地上アマチュア局受信(145.800MHz FM)

地上局は 437.050MHzと145.800MHz 両方が受信出来る。しかし ISSのレピーター
が稼働しているので、ISSレピーターへ 437.050MHz FM でのアップも可能だった、
ということだと思われます。(18 Aug 2018)
