From AMSAT-UK:
In June 2022, Her Majesty The Queen becomes the first British Monarch to celebrate a Platinum Jubilee after 70 years of service.
AMSAT-UK has decided to send a special Platinum Jubilee greetings message via FUNcube-1 (AO-73). Anyone who receives this message and uploads it to the Data Warehouse using the Dashboard can generate a certificate to remember this historic event.
AO-73/FUNcube-1 is transmitting the Jubilee Fitter message on the BPSK Telemetry beacon which has a nominal frequency of 145.935 MHz +/ Doppler.
Note!
The link to the certificate web site can be seen in the fitter message.
