[Ground-station] Earth-Venus-Earth reports (next stop, October 2026) and ORI's link budget work

[Michelle Thompson]

Greetings all!

You probably know about our recent link budget work. The Earth-Venus-Earth
event happened this past weekend. Congratulations to Dwingeloo and Stockert
for successful signal detection. This is an achievement that has not been
accomplished in the amateur service since 25 March 2009 by AMSAT-DL at
Bochum Radio Telescope in Germany. Given that the anniversary of this
remarkable achievement is tomorrow, then the news we are able to share is
delightful indeed.

Here are some initial reports:

Here is Dr. Wolfgang Herrmann's Earth-Venus-Earth (EVE) report on the
Society of Amateur Radio Astronomers (SARA) list can be found here

Here is Dwingeloo's report from their website (very nice mention of ORI!)

Deep Space Exploration Society (DSES) attempted detection with a
transmission, but the signal was not received.

If you would like to join the effort to make the most of the October 2026
inferior conjunction, then the time to join is now. The goal is to move
beyond detection into communication. This challenge is very difficult.

ORI's link budget work can be found here:
https://github.com/OpenResearchInstitute/documents/blob/master/Engineering/Link_Budget/Link_Budget_Modeling.ipynb

ORI's goal for this document is to continue its educational and predictive
role for interplanetary communications in space, and to spark interest and
activity in EME and EVE efforts. People that want to do amateur radio
satellite communications need resources that explain the communications
channels of space in an accessible and citizen-science friendly manner.

If you know someone that might want to be a part of this mission, then
please direct them to https://openresearch.institute/getting-started

Or, file an issue or pull request to improve the link budget. We value your
opinions and expertise.
