Go over to www.P25ca.org we are linking stations using Motorola UDS v.3225 Modems and OBI-100 Voip boxes. Next is to get a Astro-Tac so we can connect to it.

I am not disappointed at all with the GTR8000's. We are using the Summit six pack configs and they are super nice. Motorola did have some problems with power supplies, cannot remember who made the supplies for them, but those issues have been worked out. Knock on wood, we have 3 summit Six packs and...

Just got a new APX in and the rubber boot is removed now. FYI

MOEtorola

After not having time to mess with this issue, I had a little time and figured it out. The Channel ID's in the monitor and the radio MUST match exactly. It works perfectly now. Using an APX I can can switch the monitor from 800 to 700 or VHF and the radio imediatly switches and reg., aff. and PTT. A...

I'M READY!!!

Keeping eyes peeled for a good used quantar.

It just a sales type of thing, to show the iner workings of the antenna.

My 2975 has

Great thanks, for testing this. Although I did not ever recieve a channel grant after powering off and back on. I did however get the same 0rssi as you. Did you ever get the continuous registration to occour? Did you play with changing the sites and going into site trunking? It just boggles my mind ...

I am looking for a technician that has worked on or maintains a single zone system with both 7 and 800 sites.

I have some ?'s regarding CC's.

Please this topic.

You got it, thats what I did with mine, works great.

MOEtorola

I still maintain that the issue you're experiencing is that you're not changing the Site ID when you wish to simulate a different band, but I could be wrong... I have simulated changing the site ID, no go. Although the CC does put out adjacent site id information. The only thing the radio uses this...

MOEtorola

Well, after a phone call to Motorola it appears to not be possible. Even he seemed a little stumped, as to y it will not work, as the radio will let you enter any control frequency combination in programing. It appears that what ever band is enters first into the channel ID list, is effectivley the ...

MOEtorola

I'm questioning whether Motorola has ever said the APX will allow you to trunk a multiband system as one system instead of separate systems? Not sure, the reason for playing around. Do you have any proof that the current firmware supports the ability to roam between bands? It might be defined in th...

MOEtorola

Have you found anything official from Motorola saying that you can put a mixed frequency trunking system in the apx (besides 7/8)? Not sure what you mean. But if your refering to vhf or uhf trunking in the apx,, Yes I had mentioned above that my APX will trunk on VHF, 700 and 800 with no problem. I...

MOEtorola

I had mentioned at the first post Oh, and the radio does not go out of range, it appears that the radio is hearing the control channel, but will not register. To add to that....... Both apx and XTS radios also show an RSSI of 0 ? if the radios is showing RSSI of 0, y is it NOT showing OUT OF RANGE, ...

MOEtorola

OBT is Other Band Trunking, which is what VHF and UHF are... I know what OBT is! LOL I'm thinking that perhaps the radio is going, wait a minute, I'm on the same system, the control channel has changed, but I'm on the same site... wtf? The radio does not care what site it is at, as the monitor does...

MOEtorola

Ah, the magic words... so I'm guessing you haven't tried this configuration on actual infrastructure yet? Lol, I wish we are only 800 right know. But that may be changing before to long. Reason for testing, be ahead of the curve , if ya know what i mean. I know I've simulated P25 systems on my moni...

MOEtorola

Ok, sorry I was speaking Motorola never messed with Tait

MOEtorola

Right off the bat, 700 isn't +45, it's +30... It doesnt matter a long as the service monitor matches the channel ID setup or if it was infrastructure for that matter. And like I said earlier, 7/800 and/or VHF does work if entered seperatly in a trunking system profile. So it makes the channel ID pr...

[quote][/quote] An XTS5000 on a system with 700 and 800 sites, for example, would have two entries in the ASTRO25 Channel ID table, one for 800 and one for 700 (usually in that order though I s'pose it makes no difference). This is exactly the way I suspect it should work, but it is not working for ...

MOEtorola

Ok, say you have a system (same SYS id) that has 1site that is 800 a 2nd site that is 700 and a 3rd site that is vhf. Should you not be able to put the control channel of each of these sites in the control channels list in the CPS in trunking sytems? The only way I can get it to work is if I create ...

MOEtorola

You really cannot use the RSSI values as a reference, for one thing they are programmable. I am assuming you used a P25 service monitor like the aeroflex's 2975 super nice monitor to reference the RSSI values to dbm readings. If that is this case, it really tough to come up with an accurate dbm read...

MOEtorola

Hey all. I am new to the whole Infrastructure side of radio so please excuse my ingorance... In, oh say, a SmartNET trunking network that has 1 control channel and 7 possible talk channels, would each site in that network have to have 8 individual repeaters for it to work? -Jake It depends if it is...

Emcomm "and whether you'd like to accept it or not a CC is a one way transmission" I stronly Disagree, A CC is not a one way transmission. Paging, TV, FM/AM radio, examples of one way transmission. I guess a guy could argue the point that a ham repeater is one way as well, if you consider...

I'm not sure that USrps have any thing to do with what we are talking about.

Thats what im screaming,, LOL Surley there are some sharp code writers out there that can get the basics going. astriks is a start just need the code to keep track of subscribers and talkgroups....routing to sites.....Now this is a topic guys..

Good info here in the thread. Regarding TRBO on simplex, my understanding is that it drops to a single timeslot but still goes out in digital. Not sure if I understand correctly though, but I recall reading that the repeater was needed to keep the timing correct for 2 timeslot transmissions. When m...

Again not trunked.

A thought I had a long time ago, wouldnt it be cool if some rich amateur purchased a P25 master site (the brains of a trunking system) and let amateurs across the country connect sites to it. For a sort of a nation wide trunking system. Just food for thought. I have not really thought much about the...

MOEtorola

At 19seconds the chirp heard is MDC1200, but partly muted due to the DOS mute setting, The tone you hear when he keys the radio, kinda like four or so beeps is astro conventional. On Astro convetional u can still setup talkgroups and Radio ID's and not be on a trunking system.

It is a simple question? Can the Digitac Comparator be upgraded for IMBE P25. I have astrotac rx'ers. I assume that NO NO NO it cannot. Since is was for Securenet the digital format is totally different. Hopefully there are no hidden tricks to get it to pass P25, like one answer i got was,,, that (t...

Any body ever want to remote dial up 1,2 or more MTR2000's using the MTR2000 RSS? Its great for checking temp, VSWR, DIAGS, or even change the frequency. Just need modems, and for multiple MTR2K's A baytech serial switcher. Ill post more if anyone is interested.

Even though you are using one PL tone out , i think it should work, correct me if im wrong. Also I run MDC-1200 through my system and it works great. One thing too mention, if you use MRTI (autopatch) on this set up, you may have to hold your access tone (*) a little longer to make up for the inhere...

I have the same setup, and it works good. I am using a MTR2000, CSI TP154+ with EX-8, and doug hall voter. My links are RF, they are maxtracs with zeatron model 38's on them. So you can probably already see how i did it. It takes alot of community repeater controllers, one on the main and one on eac...
