On June 20 and 21, the Tanusha satellites will be connected to an antenna on the ISS Russian Service Module and transmit voice messages on 437.050 MHz FM with 145.800 MHz FM relay.
The AMSAT-NA website says:
ARISS-Russia, in collaboration with the Southwest State University in Kursk, Russia, are developing a series of educational CubeSat satellites called Tanusha.
Two Tanusha CubeSats were developed by students at Southwest State University and were hand-deployed by cosmonauts during an August 2017 extravehicular activity. These two CubeSats are performing cluster flight experiments through communications links.
A second set of CubeSats, Tanusha 3 & 4 were launched earlier this year and are currently on-board ISS. Tanusha 3 & 4 are planned to be hand deployed by Cosmonauts in August. They will perform even more comprehensive cluster flight objectives than Tanusha 1 & 2.
On June 20, Tanusha 3 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on 437.05 MHz. These FM transmissions will include greetings from students in several languages, including Russian, English, Spanish and Chinese.
On June 21, Tanusha 4 will be connected to one of the ARISS Service Module antennas and will transmit from 0730-1200 UTC on the same frequency: 437.050 MHz.
The ARISS-Russia team plan to also retransmit these signals on the standard ARISS 2-meter downlink, 145.80 MHz 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 145.800 MHz FM.
Note: the Doppler shift for the 437.050 MHz signal will be +/-10 kHz.

Radio Amateurs in Canada — primarily in the Province of Quebec — have mounted a petition drive demanding that members of the House of Commons prompt decisive regulatory action against a Quebec resident who has been causing deliberate interference. The petition does not spell out the particulars of the allegations but says the alleged offender — apparently unlicensed — is already known to authorities. Petitioners claim that the individual’s “malicious intentions” have been “threatening the security of emergency radio communication in the province,” and they called upon Parliamentary lawmakers “to ensure the security” of HF radio communication.
“For 2 years, a Nicolet resident, near Trois-Rivières [Quebec], illegally set up a transmitting radio station and is generating interference on purpose,” the petition recounts. “Amateur Radio operators in Quebec have identified the illegal radio station and brought it to the attention of Innovation, Science and Economic Development (ISED) Canada, and its inspectors seized the individual’s radio equipment.” One of ISED’s functions is telecommunications regulation.
According to the petition, the alleged offender “acquired new equipment right away and returned to jamming the airwaves.” The petition identifies the alleged offender as a male who is “known to police in Nicolet and Trois-Rivières” and “has regular encounters with the law.”
“We are calling on the government to provide more support to the Department of Innovation, Science and Economic Development Canada, so that it can intervene more decisively in this matter,” the petition declared.
Radio Amateurs of Canada (RAC) — the country’s national Amateur Radio organization — was noncommittal. “While we have not had a chance to investigate the specific details of the incidents [that] the petition refers to, we agree with the importance of acting to support the security of high frequency communications,” RAC said this week.
As of June 12, the online petition had gathered more than 625 signatures, primarily from Quebec and Ontario. Canada has more than 50,000 Amateur Radio license
