ACARS

受信機でACARSの周波数にセットして、アプリを起動すれば受信出来るので… 暇つぶしにはなるけど…。

I want to be able to plot on the map not only displays the data simply.

確かに文字化けしますが… 以前、AORから出ていたARD-2くらいのデコードと思っていた方がいい。

ハンディ機のスピーカーにマイクを向けると、ピッという音ともに文字データにデコードされます。 アプリでは文字データまでで、後は脳内変換するしかないのですが、私は知識不足のため便名までしか解りません（笑） 受信がうまくいかず、文字化けする場合もあります。

起動さえしてくれないので、どうしようもありません…

The app does work, but requires some tweaking/experimenting with the microphone and speaker placement, signal/antenna. Pretty good app, would like to see an update though. I copied signals from two different radios, an Icom ICR6 Communications Receiver and an XHDATA D808 portable shortwave radio . Both performed reasonably well tuned to 130.551 mHz Air band (AM).

First make sure you can get the RF from the planes as high quality as you can (good antenna, receiver tweaks). Then it will require various experimenting placing the iPhone in good position so the phone mics can hear the transmission. And also experiment with the receiver’s volume. You will see the data scrolling on the phone screen if you get all of the above correct. Now look at your data for quality decodes. If the data looks garbled, play around with the settings and positions again. And....in the app’s configuration, make sure you have a file selected to store the data on the phone. Another thing I really dislike in the app is that if you open another app, all the data displayed in the ACARS screen goes blank and then if you want to view the data, you have to open the stored data files. It does this everytime you goto another app on your phone. I want to try this app after adding an external microphone to my iPhone 8+ via a splitter cable. I really hope this will help with the decoding of crap data to quality data. Good luck - when all is tweaked correctly, it is a great app. But honestly, use PDW on a PC.

VERY minimum application, it receives ACARS and that's it. You can put your earbud microphone next to radio speaker, but best bet would be a line-level microphone input. Even if packet doesn't fully decide properly, you get what does decode. Thats a plus. Wish it could run in the background. Only thing I understand is Tail number and type aircraft in packet. It would be nice if the rest of the jibberish is translated to what it actually means. However, it does work. I use in with SDR on the Airband.

Needs support for Apple Watch

I have used top notch ham decoding apps and bad ones. I'm current iOS and this app works beautifully even unsquelched. This is my first time playing with this mode and this app let me confirm some very useful info. Even jumbled garbage tells you something. I had a minor career in comma and I am going to rate this a 5 because it works off the air( no cable), you have virtually unlimited number of folders. An improvement would be to have a bigger buffer per file but hey, it was worth it's weight In gold to ME, others not wanting specific data or range extrapolation might not rate it as high. All in all, if I wanted to follow say a friends aircraft using a minimal outside antenna for about 250 miles with just a used scanner and iOS device can have an easy relatively advanced system incorporating this quick down and cool app. I'm not into iOS, computers or apps and have no idea who or how this was written so take my 5 stars for what it's worth and who wrote it. A forever novice to iOS and apps!
