It looks like Tanyusha 1 was activated on schedule today, as I heard
it on 145.800 MHz as the ISS passed over the western USA around 1918
UTC today. This was a very high pass over central Arizona, maximum
elevation of 62 degrees. As I tried (unsuccessfully) to work stations
on the 145.825 MHz packet digipeater with my TH-D74, I used the audio
recording function on the HT to capture the signals on 145.800 MHz.
My recording would momentarily cut out whenever the HT transmitted,
but I only missed the identification before one of the 3 messages I

According to the ARISS press release from last week, Tanyusha 1
transmits messages in Russian, English, Spanish, and Chinese. I copied
3 of those 4 messages, missing only the Spanish message. Before each
message played, the satellite would identify itself in English, "Romeo
Sierra Six Sierra".

I have posted links to the recordings I made in a post on the QRZ
satellite forum earlier this afternoon. That post can be found at:


The MP3 files with each of the messages, the RS6S identification, and
the WAV file from my TH-D74 can also be found in my Dropbox space at:


(look in folder "20170704-ISS_on_145.800_MHz")

I'm not sure if I'll be able to get much from the other satellite
once it is activated, since pass times aren't very convenient for my
work schedule later this week. It would be nice to get the Spanish
message, to go with the other 3 I copied earlier today.
