the chip moved over once you started posting crapivahri wrote:Well you would be the last person on planet earth I would tell what the flaw is... I wouldn't post it on an internet forum.AML wrote:You alerted Moto to a flaw ? LOL, and what did they say ? considering they can't fix piles of XTS5000's with a simple fault and wanted to replace the entire radio fleet. I suggest their "Tech" look at a batlabs link and hey presto, radios fixed. I'll mention another one, ever seen a Moto representative in court ? I have(several times), when asked basic questions on the production and specs of gear, the reply was "I'll need to contact our expert in the USA", considering that person was listed as "expert radio communications witness" I was stunned.ivahri wrote:AML,
I'm sorry but your version of history is totally wrong. MDC1200 was a Motorola proprietary standard unsupported by any other vendor till only recent years. 5 tone signalling was the overwhelmingly dominant form of selcall/control in Australia- how do you think the users of Philips, Tait, heck even going back to STC got around this? I go back to the old Sigtec decoder/encoders, I even remember fitting Sigtec boards to a variety of different radios, and no MDC1200 was ever offered. This was an American standard... You must have grown up on Motorola radios.
And you don't need CTCSS to listen... anything more is handy maybe, but not essential to permit someone to monitor. Most agencies use multiple CTCSSs, you have to for frequency reuse. That doesn't stop you listening- heard of FM capture effect? The strongest signal will get through CTCSS or not.
You really have no idea of what is going on behind the scenes to permit almost seamless roaming between state GRNs. I was discussing this with one of the network managers yesterday & it is distinctly possible in coming years. Security standards between the networks will be a very big issue... I identified a big flaw in one (not NSW) only yesterday & alerted Moto to it.

Limited knowledge behind the scenes hey. and years to come ? of course its in years to come. its listed specifically in the requirements for some "groups" to shift onto the GRN and only have to carry one radio instead of 2 like they do now. lets see what happens when the grn shifts over to 380-430mhz.
Ive been using motorola for many years . along with tait, phillips/simoco, kenwood plus others.
FM Capture, what a crock. Ive sat in radio huts with multiple repeaters blasting away on high power with no bleed. CTCSS/DCS or NAC is needed for anyone wanting to not hear anything apart from what they specifically want to hear.
Ive maybe had radio bleed on a few occasions when around radios that are so far out of wack it would prob cook your nuts within a few minutes
I don't know what drugs you are on. You don't have multiple repeaters on the same channel in a base hut, do you? So how does capture effect, as in multiple signals on the same freq relate to a hilltop situation? Adjacent channel, receiver selectivity, and proper filtering is another issue entirely. But the whole idea of CTCSS is to stop distant signals normally at a lower level from opening the transmitter.
If you worked on Tait & Philips as in FM90 and PRM80 series, or T700 or earlier you would know that NONE of these offered MDC signalling and nor was it available in the Sigtec de/encoders used by virtually everyone... so your comments couldn't be right because it was physically impossible!
My only response to your comments about Moto techs is... some people DO while others just TALK. So which one are you? I have my own opinion. There are good Moto techs & there are bad Moto techs just as there is in Tait, Simoco and every other company. But if you think that Moto are a bunch of dummies I wonder how they could roll-out some of the largest, most sophisticated P25 networks in the world. Ah Yes! Because they read Batlabs... ho ho ho... move the chip to the other shoulder AML, you are about to lose your balance.
Cheers

not all users care for motorola radios, maybe you failed to read that in my post
now of course Motorola have built many systems around the world, so have ALL other service providers for half the price. lets talk about these systems.
75% of moto customers are govt services purchased with grant money secured only because other manufactures were locked out of the contract. like the GRN for example!
but, we know how moto have recently lost that now.

Well that makes sense - all the RF interferance they get in America from Sydney.ivahri wrote:Sorry guys, now I know we have an AMERICAN troll... not gonna bite anymore at this nutter...
You must pay tax to cross this bridge!
Re: Channel X
Unfortunately you are wrong, maybe you and I can meet up for lunch in Greenacre if you wish. we can talk radios,repeaters and RF. interested ?ivahri wrote:Sorry guys, now I know we have an AMERICAN troll... not gonna bite anymore at this nutter...

Re: Channel X
Well when you catch up with the facts about the Australian radio industry as distinct from your brand prejudice and your nonsense about the world all being in Motorola's pocket, then yes I'd have lunch with you. Otherwise I'm sure you can find someone else to pester. The rest of this forum has become bored with this and I'm not interested in fighting brand wars, it demonstrates total immaturity and a lack of professionalism.
Take it for granted you are on my ignore list.
