FEMA Region X (10), headquartered in Bothell, Washington, will exercise 5 MHz interoperability channels, as an option for disasters and emergencies, on the opening day of ARRL Field Day, Saturday, June 23, 1400 – 2000 UTC. Frequencies are 5.330.5, 5.346.5, and 5.403.5 MHz (USB). Stations from FEMA, the Department of Homeland Security, the US Army, Air Force, […] Read more
As part of upgrades to the ARES® program, ARRL will phase out traditional hard-copy report forms later this year in favor of an online system, ARES® Connect — a new volunteer management, communication, and reporting system. The system, in beta testing since March in four ARRL sections with large ARES organizations, will allow ARES members to log information […] Read more
Experimental operations now under way on HF appear aimed at leveraging low-latency HF propagation to shave microseconds from futures market trades and gain a competitive edge in a field where millionths of a second can mean winning or losing. Bloomberg on June 18 reported on a secretive antenna facility near Maple Park, in Kane County, Illinois, and speculated that […] Read more
Each year as ARRL Field Day approaches, state and local governments traditionally take advantage of the opportunity to honor Amateur Radio in the form of various proclamations. This list of those that took part is not necessarily comprehensive. In Alabama, Governor Kay Ivey proclaimed June 18 – 24 as “Amateur Radio Week.” A delegation of radio amateurs […] Read more
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.
