I have thrown an example recording of the SuperDARN system on my YouTube channel.

This was recorded on March 30, 2020, at 1449 UTC, on 10500 kHz. The radar was pinging on that frequency for quite an extended period of time. Most often SuperDARN is frequency agile, bouncing form frequency to frequency in a given band. This one, setting on a given frequency for minutes at a time, was a great opportunity to grab and example for the YT channel.

There are different SuperDARN sequences used at different locations and a given location may use different sequences at different times. See the attached from January 2020 from visit to two sites.

Also, your sequence is one of the standard ones using 0T 9T 12T 20T 22T 26T 27T with T=2.4 ms.

Actually, I had that sequence already, but I was missing an important part, the 2.4 ms for T, so it all did not make so much sense. Now that I know T=2.4 ms I get how it fits into my vid. Thanks.

Same T (but different sequence) as Wallops. (Blacksburg used a different sequence but T=1.5 ms in my observation above).
You may want to look at https://plasma.newcastle.edu.au/research/fitacf/acf_tutorial_mcwilliams.pdf
May be you got the sequence from it. It is a 20 MB file so you will need to download from there. The paper mentions some sequences being better for lower HF frequencies.

Actually, not sure where I grabbed it form, maybe here: http://www.tokenradio.net/Radio/SharedFiles/InfoTfer/1025.pdf

Thanks for the link, I will add it to my library.
