Lately, there has been some confusion among our followers as to where they can find the most current operation status of our radio equipment on board the ISS. Here are some links that should help.
The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html
The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html
Hope this helps.
