Well. I don't think the stream is that bad! And compared to what was available the last few months for LSGG (namely zero), it is so to say infinitely better... ;-)

In my experience, an outdoor antenna brings a lot. And of course one of the well-known RTL dongles (RTL SDR Blog V3 or NESDR SMArt).

Maybe there is a possibility to receive an additional channel from your position later, which does not fit into one of the received frequency windows with the other two setups. This would then complement each other well.

Hi quelbazar

Thanks for your information and the URL to the temporary stream!  :-)

I am currently listening to your stream and can follow LSGG Arrival over it well. The signals are quite clean - but all (controllers and aircraft) rather on the weak side with a relatively large amount of white noise. Do you have the antenna inside or are you very far away from the action? You might be able to increase the signal-to-noise ratio just by increasing the gain in the configuration.

I will send you a private message here in the forum with our internal test streams. Please do not spread this. We are now approaching Dave to have these streams on LiveATC very soon.

Hi Thowe,

I fully agree : My stream is not clean enough. I've a (very) low cost USB dongle, a basic indoor antenna, and I'm 60km away (east) from airport. I tested many gain configs with no changes. Putting antenna outside is worst  :? .I ordered another usb dongle and a better antenna.
But your LSGG arrival stream is obvously better than mine. Dave will have to use your source.  :-)

Thank you for your work and for your advices !

Once again proving the 767 has ample power.

Listener Forum / No CYTZ?
« Last post by mangadragonnet on October 10, 2021, 05:35:43 AM »
Im curious if anyone knows anything about CYTZ being seeded?  Are there any plans to seed it? "If and when" it might be up?  It is a decently busy little airport, with a regular airline, and 2 flight schools flying out of it, on toronto's island.  Im actually a student pilot that flys out of there regularly, and would love to be able to access that atc feed!  Seems everthing else in the area has a feed, but not YTZ?

Hi Thowe,
If you want to focus on something now, I would target the tower frequency. Especially if you are close to the airport and receive the aircraft on the ground well.

Unfortunately I'm not close enough to the airport to cover tower frequency.

Together with two other enthusiasts we are preparing a huge offer for LSGG. From Radar Upper Level to Tower and Ground everything should be available in very good quality at the end. A part of it might go online soon.
OK : My coverage of 136.255 is not a "top quality" reception, especially when the weather is bad. When available, your coverage will be more complete, and certainly with best quality. LiveATC suhould publish the best quality, I agree  :-D.

Thanks for the info.

You can only stream two frequencies separately with one dongle if they are within a 2.5MHz window. Otherwise you have to configure a frequency scanning mode where you only hear one frequency out of many. Details can be found in the RTLSDR Airband Wiki.

Aviation News (General) / How did Delta Airlines awaken 570 dormant aircraft?
« Last post by KB4TEZ on October 08, 2021, 12:45:44 PM »
Really interesting read.

https://www.freightwaves.com/news/how-did-delta-airlines-awaken-570-dormant-aircraft

AskWaves describes the technical work behind parking, storing and reactivating aircraft during a pandemic. Delta Air Lines parked 571 mainline aircraft across the country in 2020 when the COVID-19 wiped out most passenger travel. Airlines still have about 70% of their pre-pandemic international capacity in hibernation, but Delta is returning aircraft to the skies because the U.S. domestic market is recovering faster than in other parts of the world.

Parking a plane and bringing it back to life after months of inactivity isn’t as simple as turning the engines off and on. It takes a lot of effort, including maintenance and electrical checks, to keep an aircraft in a ready state for future use.

As the pandemic reached the U.S. in March 2020, Delta (NYSE: DAL) began parking aircraft in Blytheville, Arkansas; Kansas City, Missouri; Marana, Arizona; and Birmingham, Alabama. Each location had separate challenges, such as humidity, desert heat or bugs and small animals nesting in crevices.

In some regions of the world, for example, mud dauber wasps clog exterior speed-sensing tubes with mud. Maintenance personnel are instructed to regularly check the probe covers for damage.

So many aircraft were flown into the Birmingham airport that Delta technical teams ran out of the chocks placed by the wheels to hold the aircraft in place. Workers bought 6-by-6 skids of wood from local hardware stores to hand-make replacements, the airline said in a recent blog post.

Finding airports and fields that had room for aircraft was a big undertaking itself. In San Bernardino, California, a designated parking area wasn’t usable after a  Boeing 757 began sinking into the pavement. And runways in Kansas City and Victorville, California, were only temporary, so the planes eventually had to be moved again. Planes in long-term storage also need special covers placed over the engines and fuel to be removed if they are kept in a hangar.

Delta TechOps scheduled maintenance work for each aircraft at seven, 14, 30, 60, 100 and 180-day intervals. Coordinating the checks and spreading out the work required extensive planning, according to the airline. The engineers developed flexible “job cards” for each aircraft specially tailored to the climate conditions where they were parked, while conserving supplies and manpower.

“Putting an aircraft to sleep really hasn’t been done in the Delta world before. Some of the tasks have never been written for a lot of these airplanes because they were fairly new,” a maintenance program manager in Atlanta said in a Delta video.

The pandemic complicated the storage efforts. Most mechanics commuted to different storage facilities for periods lasting a few days to a month and couldn’t eat at restaurants because they were closed. At one location, a chief used the hotel kitchen to make meals for his team.

Many stored planes were stripped of certain parts to help repair planes in service. When it was time to reactivate them, mechanics had to find and reinstall new parts.

All planes reentering service have their systems activated and reviewed, and gears and components greased. Then they undergo a test flight before going to a repair facility for a maintenance overhaul, according to Delta’s blog. Smaller planes can take about 10 days to two weeks to rehabilitate. Larger aircraft can take two to three weeks to fix up. The process is longer for planes stored 180 days or more, especially if there are expiring components that need replacement.

When the maintenance is finished, pilots arrive to fly the plane to an airport where it will pick up passengers and cargo.

So far, Delta has returned 493 aircraft to the active fleet. The company expects to be reactivating aircraft into 2022.

There are no messages from you in our support system. Please PM me offline with a ticket number if you have one. But checking your email address there is no contact.

18 months after, I'm back  :wink:

I've done a successful rtl-airband config. I can now provide :

LSGG Geneva Arrival: 136.255
OR
LSGG Geneva Departure 119.525 (or 119.530 ?)

I don't know how to provide 2 freqs with only one dongle.

I will fill the ad hoc contact form and DM to Dave.
