I am sure all of you know that Nextel sucks big donkey balls but seriously, are there some portables that are better than others that reject their crummy, noisy TDMA garbled crap than an STX821? My poor STX is a great radio and could hear a pin drop but it goes deaf around a POOPTEL site- it isn't affected by CDMA 800 (better format anyway- spread spectrum- can even touch the antenna of my StarTAC while in use and doesn't add a bit of noise to the STX) but goes to **it when within a 1/4 mile radius of one of these noisemaking POS'es.
And before you flame, check out APCO's Project 39, which is addressing interference to 800MHz public safety systems, mainly from NexSMELL.
Are any of the newer radios really better than say, an older STX (better front end)? I am being offered an MTS2000 but it will be no value if it just as tormented by POOPTEL interference. I merely monitor for a hobby, but I would REALLY BE PISSED if my LIFE WAS IN JEOPARDY because my 800 radio went dead so that POOPTEL can rape, rob and pilfer from it's customers by providing their HORRID so-called service. Is anyone else experiencing interference from POOPTEL and what radios handle better than others. The systems I listen to a simulcast SmartNet II and have both splinter and standard channels in them (had to give up the GTX I bought when the local system added 9 new splinter channels to their standard 15- the radio would not work when given an assignment to one of the splinter channels- so the GTX/MaxTracs are out). Damn POOPTEL has a site they just stuck up right next to my subdivision and it makes my STX sound like some cheapo RadioShaft scanner.

any ideas?

Not trying to be an ass here, but what is the point of converting the nations public safety system up into the 800Mhz band anyhow? Shouldn't they have seen this one coming? Afterall, the cell towers have been up longer than many of the 800Mhz public saftery systems anyway. Regardless, my local law enforcement is out of my lsitening capabilities having gone digital- and I can't decode it- and furthermore, I don't use a cell phone, probably never will, and can appreciate your views on how they are building far too many towers. I can almost always see one no matter where I am these days.

I have an MTS2000 and MTX8000 and both suffer when near a Nextel tower. As for CDMA, they pickup interference from my cell phone when within a few inches but the CDMA interference doesn't really hinder operation (in my opinion).

I too would hate to risk my life if I was dispatched into a building near a Nextel tower. Reception and transmission is very bad unless I happen to be near our base tower.

I love the fact that Nextel is buying up 900 SMR space now too. I don't think they're going to operate up there because of equipment upgrades and what not, but I think they are buying out the SMR market as a whole.

Another funny fact: most people think that because Nextel is digital that they can have a secure conversation. Ever use a Nextel and actually get Nextel X-talk? I actually could talk with another pair of people at one time because I was thrown onto the same channel as someone else. (It's happened on CDMA as well....)

My 2 cents.

Hey Nextelsucks,

Why dont you just get a high powered 800 conventional mobile, go to the FCC website, type in you location and service and get the Nextel Freq's. Then program them into your High powered mobile and key up while another nextel is keying up next to you. This somehow screw's up the system and pretty much shuts the site down (temporarily). I personally have never done this (although would like to sometimes) but know people who have back in 1996 when nextel first came out in our area, and said it does indeed screw their site up, and drives thier field tech's nuts. I guess sometimes you gotta fight fire, with fire, especially when your hobby is slowly being choked out by ruthless nextel executives in $2,000.00 suits. Oh by the way, isn't it interesting how William Kennard, former Head of the FCC, under Clinton, is now one of Nextel's high up's? I'd like to see Nextel Partners contribution to the Democratic Presidential Campaign......Talk about a near perfect execution of completley monopolizing an industry...I thing they make microsoft look like they did nothing wrong.

no, I am RTM.

and as far as the issue of putting public safety on 800mhz, they were there long before the cell boom. at least around here, our first trunked system went up in 1984. and cellphones aren't the biggest offender, POOPTEL is- they are an ESMR and use channels intertwined with pub safety on 851 and 861 not 870-894 like cellular. And nextel didn't exsist as a digital ESMR until 1993/1994. Go read the info on project 39 at http://www.apcointl.org for more.

I do find it rather fishy that ex-FCC personnel are now in the high up of POOPTEL. But what would one expect, public safety get treated like second class citizens by the FCC because they don't spend billions of dollars in these bogus and staged spectrum auctions. What a shame, and this is putting our local heroes lives' at risk.

Hello.

http://batboard.batlabs.com/viewtopic.p ... &forum=1&5

Perhaps a bit of understanding is in order.

The 806 to 890 MHz band was carved out of the UHF TV band, the transulater band to be exact, what this was, there was a UHF transmitter on a hill, usually rural areas, this was a relay for the regular VHF or UHF TV channel.
Now, some of the old transmitters were left in place, several I have come across still will work as is, real common out in the boonies, also remember, the mexican government has NEVER signed off on the agreement for anything but analog cellular.
The law allows a 150 mile area between the 2 countries that must follow ITU/UN policies,
The US told mexico " there is nothing we can do, they said OK.
The problem with iDEN is that the RF curve for TDMA is too sharp, lots of adjacent channel noise, indeed, take a AM/FM radio, tune between stations, and you will hear a sharp tic tic tic if a iDEN handheld is anywhere near.
This noise looks like a giant spike on a spectrum analyzer.
Remember, it is against federal law to jam another station.
