Is it possible to hear Nextel walkie-talkie conversations with a scanner? What about the Nextel "off-network" walkie-talkie conversations?

All of the transmissions will be in the blocked chunk of 800mhz bandwidth so most scanners (especially newer ones) won't get you anywhere.
The 'directconnect' or whatever they're calling the off-network walkie seems really cool though.

Nextel uses iDEN. The modulation is 16QAM. The voice data is VSELP. You'd need a receiver that could do both. I don't think there's a consumer grade scanner that will do this.ltng92 said:
No, they are in the same un-blocked portion of 800 mhz as other trunked 2-way systems.Matt_45 said:

my i870 will do off network, i've never used it but its there if I need it
My i560 is also able to do the off network direct talk. It works very well i might add. 
i760
I have an iDEN i760. No one else I know has an one capable of off network com, so I have no way of testing it. I suppose it is a simplex form or communication and has limited distance capabilities, especially since a cell phone transmits at such low power.
The initial intent was for my wife and I to have it, but she is still tied to her Sprint phone. I used Nextel at work. I know that Nextel is not on the same frequencies as other cellphones. This is why they are paying the industry to move (re-banding).
Motorola has come out with communications using the same technology, but calls it DTR™. DTR Series™ is digital on-site two-way radios using the ISM band and FHSS technology (impossible to scan using a scanner).
See this website: http://www.motorola.com/DTR/why_two...id=dtr1&WT.mc_n=dtr1&WT.mc_t=Home&WT.mc_r=120 and this FAQ site: http://www.motorola.com/dtr/faqs.aspx?WT.mc_id=dtr1&WT.mc_n=dtr1&WT.mc_t=Home&WT.mc_r=120 for more info.

Every phone Nextel sells has the Direct Talk feature. If its not mentioned in the key features list, click "view all" next to key features and Direct Talk will be listed there.
EDIT: Before someone bites my head off for not being specific. Every phone nextel sells now. I have no idea about the phones they sold last week or prior.

That head biting is going to hurt.
The featurs included in the phone (per the Nextel web site) are those with a check next to them.
There are several phones WITHOUT Direct-Talk.
The easiest answer to EVERYONES questions in this thread is NO NEXTEL COMMUNICATIONS IS RECIEVABLE BY ANY MEANS EXCEPT A NEXTEL PHONE, and or their service equipment!!! Period

Thanks for pointing that out N_Jay. Man do I have egg on my face.... hehe, get it? Its easter and I mention eggs:lol:.
The i560 has offnetwork system. I have that phone but dont know anyone yet how use it and how it works.
The Nextal frequencies are not blocked in scanners. Remember it was Nextal that obtained a lot of SMR frequencies and put their cell phone system on them and the FCC did not keep them from doing it. SMR frequencies are sandwiched between public safety frequencies and the whole situation led to the present, and very expensive rebanding issue. Not that it really matters as previous posters have pointed out, you can't monitor their system anyway.

Keeping in mind that while the Nextel phones ARE using old SMR freqs, which are not part of the Cellular blocking requirement, they are still considered a Commercial Mobile Radio Service (CMRS) just like cellular and PCS and paging, and as such are not legal to intercept. Even if you could, which you can't because of the iden encoding.
It would be interesting to see if a phone could be hacked, maybe using a discriminator output and hacking the CPU. Just a thought.

Nextel is presently moving a lot to 900 freqs they acquired here in Colo.
Also direct connect and the "Walkie talkie" feature are 2 different things. Direct connect is on all nextels and is IDEN and uses the network , Walkie talkie is not IDEN, as mentioned by others.

NEXTEL (and consumers) use the term "walkie-talkie" for the Direct connect feature.
The off network push to talk is called "Direct-Talk".
