Saturday, 21st of August 2021 town of Nizhny Novgorod celebrated it’s 800th anniversary.
In honor of this event, SURA station sent several SSTV images using their huge transmitter site. SURA is similar system as USA based HAARP.
I got all the pictures sent from the SURA, but due to local thunder and lightning some of the images were distorted because the receiver software lost the synch.
Original translation from the Facebook post:

It will be done using the unique SURA scientific device. The heating stand will transmit a greeting card, the reception radius of which will cover half the globe!
The postcard can be accepted by the owner of an FM receiver capable of tuning to a frequency of 4300 kHz, as well as anyone who wishes with the help of one of the network receivers operating on the WEBSDR technology (websdr.org).
