Weird Question

[DonnieDog]

I just took the time to notice today that searching FCC in my county and neighboring counties that there are tons of 800mhz conv and trunking freqs licensed to Nextel, Verizon, etc....

I know there are not the cell freqs because of the way they are listed and due to them being 850 and 860 area.

What are these used for??

Been scanning for years and years but yet I dont know!!

Thanks in advance.

NEXTEL is a radio service. Their frequencies fall in the same band as Public Safety (interleaved) and not in the "cell phone" bands. Rebanding is splitting them out so that they are no longer interleaved (was causing mucho interference with public safety as originally allocated).

NEXTEL looks like a phone, but in terms of infrastructure is actually a business radio with telephone interconnect ... but the human interface allows it to operate like a phone to the end user.

Speaking from experience I can say that Nextel still has some repeaters out there, same with Verizon. Why, I don't know, maybe for license holding. When I've been to the actual sites it's been LTR equipment. Typically these and the Nextel SMRs are not managed by actual Sprint/Nextel techs (I know, I used to be one).

There's a local Verizon Wireless 800 repeater in the VZW vault area but it's no longer used. Just keys up with crap on a regular basis.

Could this be helping with those direct talks? but you must be in a certain range to be apart of the direct talk group with the set channel and all?

DirectTalk is completely different. Low powered 900 ISM band stuff. No license needed. Lots of discussion on here about it.

I wish my I350 didnt break.. I would be using that constantly on patrol

I used to, too. We called it Nextohell back when...

Could this explain all of the "phone patches" and other weird TGs on a local 800MHz LTR system (http://www.radioreference.com/apps/db/?sid=3295)? Some of these seem to begin with DTMF tones.

That sounds like Unit IDing.

With LTR phone patches can be on any group. It's just simply telling the controller which group is designated for it.

Thanks. I also notice that there are these TGs (marked "TeamTalk Talkgroup") that seem to consist of a DTMF tone, ringing (like a phone), and then two people talking as if on a two-way radio with a beep between transmissions. Is this Nextel?

[wayne_h]

No, sounds like a way to signal another person to answer the radio.
