Blair P25 weakness

[Voyager]

Raised awareness on the lacking ability for these counties to talk to each other. Not meeting any government recommendations. They are 100 percent not interoperable. This kills first responders. Simple patches are unheard of.

Also I will write the paper. Few weeks.

These counties? You mean like the surrounding ones that use this system:
ICORRS (Inter County Regional Radio System) Trunking System, Multiple, Pennsylvania - Scanner Frequencies

(note the group: ICORRS Systemwide Interop Talkgroups

)

In fact, I would not be one iota surprised if Blair and Cambria join up within the next year or two. Having P25 equipment is most of the battle. And even if they don't, there are system patches specifically for other counties who are on AND NOT ON the system. Patches to analog frequencies are used, too.

Must be a bear to make calls from Virginia...

Cambria Somerset and Blair need to team up to all have UHF p25. Also linked dispatch centers. These counties have nothing matching hardware wise. Sadly cambria uses business grade radios not even public safety rated. So many affordable p25 products on the p25 conventional market. Waiting game.

I wouldn't count on Somerset, as they have other plans already in motion.

Ahhh armchair quarterback... So why P25 conventional? What makes it the best? What not analog for interop? You know about the V/U/8/7Call &V/U/7/8Tacs right? Aww never mind, your posts are so confusing, I'm not sure what your point is...

That's what I thought you were talking about. I thought you were the wise one that had written how to fix everything, except you only linked to a Motorola documents about data linking for MWS systems... Try and stay with the topic at hand... Voice interop...

These counties have little extra money to play with. Trunked p25 would bankrupt them. They have so many stations that supplying them all would only happen in a dream. Unless grants are obtained. Voice is all they want. Vhf/uhf/700/800 band Radios are a must to allow full interoperable voice. Counties in this area are all over the spectrum. Also 6 watt portables due to the mountains.

To full circle and wrap this up here is the security weakness

Just needed to tell the world that using no software and only Front Programmable Portable feature you could access the system. Then using the RID on the fly reprogram you could become any User that you want.

Ethics and law intact. This thread is now complete in my mind.
Others feel free to continue the topic about interoperable failure.

Motorola offers many features that can mess with p25 conventional. No laws to prohibit purchasing. Capitalism is a wonderful thing.

I'm done. If you would like I will post an entire paper on how to fix this area and how to obtain the money. Including hardware upgrades needed. I don't care enough to do that..

Please do. I've enjoyed your ramblings and look forward to hearing more!

Here is the paper in one sentence.

"Buy Harris products from now on" Biggest bang for your buck.

You do not need P25 to be interoperable. Plain old analogue does the trick quite well. The nice thing with a trunked system is that you can share a relative few frequencies with a large number of users. Yes the up front costs are high, but it is MUCH more spectrum friendly.

Counties in this area are all over the spectrum.

Welcome to poor spectrum planning. Unfortunately this happened long ago, before the word interoperability was created.

Also 6 watt portables due to the mountains.

This is where your lack of RF understanding shows it's self. The difference between 4 or 5 watts to 6 watts in terms of talk out range, and receive signal strength is ZERO. The only difference is the increase in current draw. To make ANY difference, you would need to go from 5w to something like 40 to see much of a difference in signal strength.

Doubling your power only gives you a 3db increase in signal strength. On a RSSI scale of S0-S9 this doubling is only half an S unit.

Known for a long time. This is nothing new.

Kinda like how you claimed to have spoofed a dispatch radio?

Then using the RID on the fly reprogram you could become any User that you want.

Last I checked you can not change the RID via FPP.

Ethics and law intact.

Sure sure

Interop is simple, the politics make it difficult, go take a look at my posts from my PC there is a useful saying: 'interop is not a technology, it is an attitude'

Motorola offers many features that can mess with p25 conventional.

So does every other manufacturer than makes P25 gear

No laws to prohibit purchasing. Capitalism is a wonderful thing.

Why should there be? To keep hackers like you from having the ability to hack radio systems?

Ahhh it's cause you are anti Motorola? Actually I would think that Kenwood, BK, or EFJ are better bang for your buck than either Harris or Motorola...

Harris unity portables. Buy these to talk to everyone. Cheap and choice of the military. Includes all bands and system types unlike all other companies.

Higher watts will infact hit the repeater more frequently the low watts.

Last post.

US GOVERNMENT ISSUE THESE POOR LOCALITIES GRANTS TO BUY THE RIGHT PRODUCTS.

PEACE!!

It does not do motorola type 2, opensky, DMR, TETRA, MPT, or NXDN. So no the unity is not the be all end all for interop.

 

[kayn1n32008]

There is no difference in talk out betewwn a 4 or 5 watt radio and a 6w radio. You need to bump the power from 5w to something like 20-40 watts to make a real difference.

Wow. The manure is getting deep in here.
