Around 04:08 "We're going to 10,000 feet right now, i'm going to hold on my shit." "i don't think anyone has weather, what are you looking at?"
"we're locked, we're on the other side of it right now."
there was a siren tone which sounded similar to one i heard before during a military exercise a few months ago: https://www.hfunderground.com/board/index.php?topic=59020.0
i did a search for 5757 khz and came across this post on a forum about Area 51 titled: "Thug flights on HF": https://www.dreamlandresort.com/forum/messages/44981.html
heard mention of going to a military UHF air frequency, 225.275 Mhz but they are still on HF for now.
it should be noted in that military exercise the callsigns were Thug-(number) but tonight the callsigns are "lock" and "flow' sounds like an ongoing op, still listening and recording all of this to post later.
EDIT: here is several hours of audio edited down to 16 minutes by removing the long stretches without comms: https://drive.google.com/file/d/1qgDSk5as3ZHxd1PbEl2OWRkL7kK6-f90/view?usp=sharing

Good catch!
-
as i promised here is the audio of what i picked up last night. i edited a lot of the long pauses between transmissions out so the total running time is around 16 minutes but this took place over several hours of listening:

I believe that the siren is a cockpit alert to notify the pilot of something that needs immediate action.
"Weather from 'KDTA'" is airport in Delta, UT
-
The "siren" you hear is the pilot disengaging the autopilot.
-
I also think they were referring to weather at KDCA, which is Reagan Intl. in Washington DC.
-
One of the players mentions ceiling over Wendover, West Wendover, Nevada, so assume they did reference KDTA airport in Delta, UT and not Reagan. Towards the end seems they're working on ada defense measures such as flares and so on, to include navigational lighting or lack thereof. Wonder if these guys are working with a drone.

Heard callsigns "straight flush" and "95 euchre" used and starting approximately at 9:11 of recording heard "turn left and go high at Wildcat Mountain".

There is also an informative conversation ongoing at the UDXF group regarding this:

Excellent catch! And thanks for providing the recording.

thanks @StrangeBeacons. btw i used to listen to your SDR before and right after i bought my first because you had a magnetic loop antenna and i was looking getting one.

Cool. I swear by magnetic loops, especially because I live where outside antennas are forbidden. The W6LVP mag loop works well with my KiwiSDR (which has migrated from Seattle to Naples, Florida now).
Again, your latest recording is awesome. I tweeted out a link to it on my Twitter feed (https://twitter.com/StrangeBeacons/status/1246104361983492099) and it has been getting a lot of likes. :D

thanks for tweeting that out. the other reason i listened to your kiwiSDR was to hear what was possible to pick up from Seattle. how does your new listening environment compare to Seattle?

The propagation here is absolutely amazing. I am able to pick up so many more signals than what I could with the same setup as I had in Seattle (lots more amateur radio operator traffic, plus signals out of the Caribbean and even Europe).

Nice jasmine, I have not reduced my receptions of this signal to audio yet, they are still in SDR format. I started receiving this around 0320 UTC or so, and the last transmissions I heard were around 0650 UTC or so.
Sounds like aircraft over UTTR.

I think "Straight Flush" was not a callsign, I think it was a threat callout. I also heard them mention "Roland". And I also heard them say something about "unable to track us through the clouds". Both Straight Flush and Roland are radar guided SAMs (Surface to Air Missile) systems. If they were over a training range, say over UTTR, it is very possible there were simulated SAMs on the ground engaging them.

They were definitely talking about ada countermeasures.

Token you are on the mark, the Russian 1S91, NATO designation “Straight Flush” is a fire control and guidance radar....https://www.radartutorial.eu/19.kartei/06.missile/karte011.en.html

Wildcat Mt. is in the southern UTTR range as described on page 95 section 6.....https://books.google.com/books?id=1EXxAAAAMAAJ&pg=PA95&lpg=PA95&dq=southern+uttr+range+wildcat+and+kitty+cat+complex&source=bl&ots=iGe-_8JNiT&sig=ACfU3U1AidU_v3hHf0fPKpBsQLosgjCCSg&hl=en&sa=X&ved=2ahUKEwirlOfChtPoAhWehHIEHQzUD8EQ6AEwAXoECAsQMQ#v=onepage&q=southern%20uttr%20range%20wildcat%20and%20kitty%20cat%20complex&f=false
