Utility / Possible COVID19 Case-Air Transat 785 w/New York 13348 khz 19:11Z MP3 recording

i just picked up what sounded like a possible case of a passenger on a flight from Malaga, Spain to Montreal, Quebec, Canada suffering from the COVID19 coronavirus. i could mostly only hear the ground station and phone patch because i'm in Seattle. what alerted me to hit record was mention of the passenger coughing, having a high fever and at times unable to breathe. the crew presumably put her on oxygen. the ground station advised isolation from other passengers, they said they needed to give her her own bathroom and that upon arrival the pilot contact the port health authority to organize medical assistance. i edited the audio to take out any identifying information including the reference number. here is the MP3 of the audio https://drive.google.com/file/d/1Nkfsf7gT1LKac7ysZJdX3CuAvCsug0XI/view?usp=sharing

"Мода, Мода, Мода я 06542, приём" being translated is "mayday mayday mayday, I'm 06542, copy". Russian naval air employs 5 digit ids to aircraft, dunno if this is related to their tail numbers or a per mission id.

While I doubt this transmission is related, last week USAF and CANFORCE fighters escorted Russian sub hunters as they skirted the Alaskan coast.

We have sub hunters too;

that's fascinating!

i also have a ton of loggings of US Navy P3s and P8s going up and down the pacific coast of washington and oregon from my 1090 MHZ ADS-B set up using a $20 RTL-SDR USB thing from Amazon and a $3 circuit board antenna from Alibaba.

Ok i found that SDR# does allow for audio recording so i pulled the IQ wavs into there and made these two audio recordings.

because there is no ability to just record audio in SDRUno and because an IQ recording is superior. one can do their own processing on the signal. besides, it's 2020, don't most people here have SDRs? it's not like you need one in order to download the software. SDR apps are free.

This must be a proprietary format for SDRuno.  I'm hearing only static bits.

it's not proprietary. it's not an audio wave but an IQ (spectrum) recording.

download any SDR application (SDR#, HD SDR, etc) and open the .wav with it and tune to 6689 khz USB

Utility / Mayday transmission on 6689 khz USB 15:27 UTC-12 March(incl SDR IQ & AUDIO .wav)

« on: March 12, 2020, 1605 UTC »

i was listening to hear what was coming in on 6689 khz USB as that was no frequency i had associated with air traffic and i often pick up interesting things in the 6-7 Mhz range out of asia, the pacific, australia, new zealand and even the indian ocean most mornings. today i heard something different.

can anyone tell me what this is? i think the language spoken is russian with the only english word heard: "Mayday! Mayday! Mayday!" 
there are two recordings which i recorded straight as IQ .wavs from SDRuno. the first one is what i think is the "mayday" transmission. the second is a transmission i recorded not long before it to try to figure out what language was being spoken.

Recording 1 "Mayday!": https://drive.google.com/file/d/11iolyMq9xru-tZRx15M_tUzhF1oOWm9l/view?usp=sharing

Was this a plane or ship in distress?

Utility / Cobra 55 and Reach 485 working San Francisco 6655 USB 13:30 UTC 28 Feb

« on: February 18, 2020, 1340 UTC »

i just heard Cobra 55 working San Francisco radio. San Francisco gave them a VHF frequency for Pappa Alpha Zulu November. not long after this i heard Reach 485 with a position report. i looked up Cobra 55 and it appears to be a USAF WC-135W "Nuke Spotter" aircraft. i googled Reach 485 and didn't come up with anything other than Reach is a callsign for Military Airlift Command aircraft.
