@@pauldenisowski Thanks for the response. I worked in HF Radio telephony long back.We used SELCAL to call particular aircraft for passing vital information. I was not sure regarding the modulation.
I'm not sure, but if I had to guess: maybe I and O not used to avoid confusion with 1 and 0 (zero) and N because it's used on tail numbers in the United States. But again, just a guess. Thanks for the question!
@@smilinggoats2505 but letters are also spelled out using the NATO phonetic alphabet for that reason (same reason niner is used because 5 and 9 sound similar)
There isn't a code for the a320neo specificaliy, each aircraft when is made has a specific SECAL code assined fot it. At the end of the video says that there are planes with repeted SECAL codes.

I'm A321 engineer from Vietnam Airlines, It's so nice to learn from your useful video.
I wondered what those tones were when listening to airliner HF radio traffic and now I finally know. Thanks for the video!

Great info, clear explain, thanks!
Thank you for this explanation.
Thanks for the feedback!
Perfect video
Awesome video. Thanks!
Thanks for the feedback!
@@pauldenisowski Plz tell what is the modulation used in SELCAL transmission
@@GirishChandra-nu2dd It's upper sideband (USB) with full carrier.

great explanation
thank you!
Thank you😊
Thanks!
Amazing video thank you
HW do atc know tat particular selcal code of a/c
It is indicated in the flight plan filed by pilots.
Effective explanation
Thank you!
What's the reason for I N O not being used
I'm not sure, but if I had to guess: maybe I and O not used to avoid confusion with 1 and 0 (zero) and N because it's used on tail numbers in the United States. But again, just a guess. Thanks for the question!
@@pauldenisowski It's because N can be confused with M when pronounced over radio.

What is the selcal code for the a320 neo??
Please watch the video again.
There isn't a code for the a320neo specificaliy, each aircraft when is made has a specific SECAL code assined fot it. At the end of the video says that there are planes with repeted SECAL codes.
Whats the reasons about Letter I,N,O have been deleting?

👌✌👍🏼
Dank!👍
Nice
Slide 3: SECAL? Whoops. Otherwise well done!
