i picked up this USB voice communication between Boeing 298 and Boeing Everett & Boeing Seattle while setting up to decode HFDL from Guam on the same frequency. i just pulled BOE298 up on flightaware and am watching its flight: https://flightaware.com/live/flight/BOE298

Hi Jasmine,

Boeing usually has several test flights per day.  I see this daily from my Flightaware ADS-B home page:  https://flightaware.com/adsb/stats/user/cnick6
They don't always communicate on HF so good catch.  Signals were quite good yesterday and look to be good this morning as well.


Cheers,
-Nick

If you are intently curious, this was tail number N370UP, a new-build 767 freighter for UPS. Ironically a photographer happened to catch this exact plane taxiing out for the flight you heard on HF:

This was a short 17 minute test flight, I'd say it's very likely that the transmission you heard was from testing while it was on the ground. For a 17 minute flight the cockpit would probably be pretty busy with other things.

I had a friend who was with the FAA. I once asked him a very stupid question about why I couldn't hear a plane switching from HF to VHF to land at Pittsburgh but I could hear the Shannon flights calling St. Johns, NF like they were going over my house? His answer, "Well Pigmeat, the Shannon ones are way up over the Atlantic, height and salt water props. The ones coming into Pittsburgh are a couple of thousand ft. over trees and squirrels. You figure it out."
