Hi,

i was wondering, i researched the analouge transition to digital, from what i can gather if and when it will be a tdma format..like the cell phones.as everyone know there is no way anyone can monitor cellphone, even if it was legal. from what i seen it will be TDMA format digital voice.

so will it end the ability to monitor avaition forever or will the serious listener have to buy a transeiver able to do the new digital mode for the aircraft band..

any ideas???????????????

It's going to take a long time before all aircraft in the US will make this move. I'm also willing to bet that the small recreational pilots may not have the money to get a radio for this mode - no doubt that, at least right now, they're quite expensive compared to their analog brothers.

I wouldn't sweat it just yet. 73s Mike

Secure Radios

they are also saying all transmissions will be secure, how does that work when you can buy a radio from icom and set it up...funny we pay taxes and they tell us what we can listen to. oh the call it security..--lol!!!!!!!!!!!!!!!!!!!!!!!!!!!

What makes it illegal to listen to cellphones is a law and sometimes proprietary formats, NOT the modulation techniques employed, which in this case could be TDMA or CDMA or GSM, etc. And going to digital doesn't necessarily mean it will be done to keep people from listening as in the use of encryption.

I'm sure in due time, manufacturers will make receivers available for aviation monitoring, especially since it looks like P25 digital Phase 2 will also use TDMA. I would say there will be something available as soon as there's a market available and is not illegal or proprietary....

Rockwell Collins Article

the person from rockwell collins, stated in a article i found online that the communications will be secure. moreover from what i read with one freq you can have up to 4 air traffic controllers talking with the VDL MODE 3-TDMA.

so the way it looks if you want to monitor them in the future 2009? give or take you will have to buy a two-way aircraft radio. i hope then we can monitor them..

its all about making money, this will give the radio people alot of money in their hands!!!!!!!!

lets hope the digital mode works and no one gets hurt with the voice not going over when changing courses when flying etc

If you find it again, send a link.
I am thinking teh word "secure" was used in a different context.
Yes, TDMA allows multiple channels on a carrier.

I am always amazed with this type of attitude.

Yep, its all about the money, we don't need seat-belts, it was just the nylon webbing manufacturers ploy to boost sales!:roll:

That's far from being a sure thing... That's only one of numerous systems being pushed, and it's the manufacturers that release all the press reports that make it sound like it's a sure thing, when it's not. Numerous groups have voted down that system. The airlines and FAA have been, are, and probably always will be, broke... They're not going to take on some huge unnecessary system if it's not needed. Making a system secure is a huge expense that's completely unnecessary, and would probably be dangerous in many cases.

I would love to know how half of the airlines in the United States plan on upgrading their system when the majority of them are bankrupt...

Over time.

What is a few $1000 (or a few tens of thousands) in radio equipment when added to the maintenance costs of a passenger jet?

"Secure" is a marketing term. It does not carry its dictionary definition when people who work for radio manufacturers use it.

Kinda like "privacy" being hijacked by Motorola years ago.

Heard It Was A Proposed

I called a company that sells avaionic radios.

from what i was told it was proposed, the FAA & FCC did not put anytime from as of yet..

VDL MODE 3 DIGITAL was proposed in 2001. companies was suppose to rollout multimode radios. this never happened, if you look at the new radios they have 8.33 spacing which went into law in 1997. so the question remains will it ever happen. i am not concerned because i would get a transeiver if scanners could not do the mode of digital VDL MODE 3.

that is one way around it.

i enjoy the airband alot!!!!!!!!!!!!!!!!!!!!!!!!!!!

Think about this people!
The FAA still has not addressed the issue of our ATC folks working with antiquated radar equipment . I have been told by friends in the business that you cant even get replacement parts for some of these things when they go. The thought of a new mode of aircraft communications sounds good in theory and it may eventualy happen, but not any time soon is my guess. The FAA seems to go by the " if it aint broke dont fix it" motto. That is ok by me....I own a transceiver and would get another one if scanners can no longer do it someday. There is no better audio anyway for aircraft monitoring than a dedicated transceiver ....

Scrambling

i searched online and even found at one poing a security research company that gave a bad rating for the VHF AM airband. 2 issues they found, one anyone can monitor the airband for commercial airliners, which they recommended voice inversion or scrambling voice mode. the second was people who was giving wrong instruction to planes to throw them off couse..so they recommended that some type of voice security be plaved on ATC
along with aircraft...to think there is people who would pu people in danger with fale transmission to pilots, that is real sick!!!!!!!!!!!!!!!!!!

as for the post above, i agree. if a scanner would not work anymore for airband i would invest in a transeiver for my listening purposes. i have one and the audio and rx is the best..

lets hope the aspect of the hbby is around for a very long time

i use a vxa 300 great!!!!!!!!!!!!!!!--if anyone is serious about their airband listening, this is the radio for you!!!!!!!!!!!!!!!!!!!!!!!!

I was under the impression that the entire move to TDMA was put on the back burner because neither ICAO or EU were willing to play along. It would have been a US only system, which would have posed huge problems.
