Well that maybe the fact that the repeater is most likely narrowband only.
If you are listening to in with a receiver that is set wide, it's not gonna be real loud

desperado

If a customer ordered an APX 8500 with the VHF and UHF deleted from the radio, is that a flash purchase to enable them or a trip back to Motorola to have the hardware installed?

desperado

always a possibility the SWR bridge is faulty.... you may consider bypassing it, or removing the output line just for testing. If you put the repeater in test mode and key it, it will run against a high SWR as well. if it thinks it's got a 10 to 1 VSWR then it's gonna turn off the output to protect ...

I know this is a rather old post but it's relevant even now so I will toss in what I know. I personally, and some others here do as well, someone that sat down and wrote an application that was more or less a PC based remote head for the Astro Spectra. The key to t was two things. The first was look...

So I am thinking that it may not be a bad idea to have the discussion of getting your console up and programmed right here so there is a record going forward of how to take a bunch of BIM's a COIM or two and a system timer and get a working card cage up and running. COIMS need to be in the middle tw...

Well, I was trying to figure out what you meant. To me none of it was Oddball. But then again I work for an MSS. Own a number of Quantars and Quantros personally in several frequency ranges. I dealt with data base stations, simulcast only Epic SCM's and all the rest. We had 288 quantars in Franklin ...

desperado

The only 'oddball' quantars that I am aware of were the data stations. These were for slow speed data transfer only. I believe they were using them in Ohio for the MDT's in the OSP cars for looking up license plates. There were a number of them in place when MARCS was still running the 3.5 system. T...

desperado

Go on eBay and look for an SCM. What station it came out of frequency wise is not important as they can be programmed for ANY freq range. Make sure that you are getting an SCM that matches the application that you have. IE don't buy a data station SCM unless you need a data station SCM because they ...

RAD has support??? I must have missed that when I spent hours on the phone with them and got no where.
And ONLY after I paid them a grand for a service contract.

I have no experience with Nokia gear, but that may need to change depending on how this all goes.

desperado

Hey, I am good with that. And if this can get worked out maybe it happens that I tie into one that someone else has. As far as the pinout,,, I really wish it was that simple. I am gonna double check the blocks and make sure they are wired from the centronix connector on the side to the actual block....

desperado

Yep, I actually have all the documentation for this. I had the option on the Ambassator switch when it was pulled and passed on it because at the time I didn't have the storage space or the forethought to keep the damn thing believing I would need it at some point. I did that with several sets of RO...

desperado

did you ever get this resolved

desperado

So, I have a grand plan... involving CentraCom consoles and an Ambassador Switch. I the CC gear but no switch. So that's the first hurdle. Thinking that with the fact the Internet is now a mostly stable and high speed data path, and the fact that TDM over IP is a reasonable thing, maybe we, the BatL...

desperado

Yes, COIMs will support an Elite console (CIE and PC) or a B&L op position. You will need the CDM software to setup the COIMS and any other cards that require programming to get them running. PM me for more information on your specific needs. You will be WAY better off to get the CDM and a coupl...

desperado

If it's Motorola gear remember that it has to be R56. So the building will need a new ground halo installed around it.
I guess my biggest question is why move the shelter? Is there some reason for the relocation?

desperado

The radios will only talk on one site and will miss any traffic that does not originate from that site. Obviously the roaming will not work to the other LCP sites. Troubleshooting this can be maddening. I had several radios that got missed during an upgrade and they would work mostly but were interm...

desperado

Where do I begin. The biggest difference with a CC2 up to the Gold Elite was the OP card in the CEB and how it was programmed. The CC2 originally Had A special set of OP cards with custom firmware that you programmed with terminal and a printer. I don't remember the names given to these cards, but I...

desperado

Get wire shark on the switch were the audio gateways are and do a port mirror or use a tap. Look at the traffic coming into the gateway and see if the audio cuts out before it is received by the gateway

Saw this thread and thought about something I have that is probably made of unobtainium. I have a MOCOM-70 head that is in the plastic. I have just the head, and it's missing the lower aluminum plate that the photocell mounted in and the photo cell. Any idea of value or where to try listing it besid...

Gonna be there in the same spot as last year. Not sure what all I am bringing to sell. I know I am bringing some VHF and UHF duplexers and most likely a stickerless XTL5K VHF high power with a W-9 head. Gonna have a VHF and UHF MSF5000 as well, Coax and connectors out the wazoo. If you are looking f...

Well, that pretty much sums up how it was done. IT was a new system as the TRBO product line was being released and was put together by old guard folks. We have a connect plus system that the one site is completely enveloped by the second sites coverage area. They were two seperate LTR systems and b...

desperado

Couple things to consider. TRBO modulation for whatever reason carries over the air very well. Break out an Ohio map and find Fayette county and Licking county. Fayette went TRBO running VHF running 40 watt XPR8300's and Licking County was running 65 watt 5 site analog simulcast. The two systems sha...

Motorola had a factory part number for a 150 foot control head cable.
They were used to connect a head in a ladder truck.
Beyond 150 I couldn't say.... and that is a factory cable, and not cat 5

Ok, Bird meters are great, if you know how to use them and understand their limitations. First limitation. A Bird 43 is either 5 or 10% can't remember which, of FULL SCALE. S a 100 watt slug at 100 watts can be 90, 110 or anything in between. Second, Where are you placing the meter? It's either betw...

Check the alignment of the consolette radios. I bet they are drifting off frequency.

desperado

First question I would have is how long is the line and second what kind of line. Here's the thing with just going by what the watt meter reads at the bottom of the line. Each connector junction has a .5 DB loss. So figuring there is a polyphaser or other lightning suppressor in the line you have 2 ...

As far as the PL comments. I installed and manage a Harris / Spectracom based 5 site 2 channel simulcast system for a county in Ohio. The Spectracom GPS and a module attached to it generate the PL for the system. The PLs that it generates are NOT right on. They range from .1 to .3 off the standard P...

OK if only 5 wires then cable is for single channel. Connect the wires per the manual and program the radio accessory pins to enable the channel change feature. Yes, wireline configuration alignment is what you need to do. You will need some sort of a audio voltmeter or oscilloscope to do the alignm...

One of the things I ran into with narrowbanding was antenna gain issues, oddly enough the antenna having too much gain and the radiation point being too low. I had a customer that had a high gain Station Master antenna on a sled mount on the roof of a building that when we narrowbanded them the radi...

I would verify that all gateways are hardcoded with a MULTICAST IP and unique UTP port. Once that is done the next set is to grab a laptop with wireshark on it and go to the far end and have then talk. See if the MULTICAST traffic is arriving at the site. Begin backing up through the network until y...

OK, tone remote control. First off, get something that you can listen to the output of the deskset (2 or 4 wire audio and ensure that it's a tone deskset and not a local control deskset. You should hear a couple short beeps and then a very low constant tone coming from the deskset. The way this all ...

no,,, not all of it. I have pulled all the red cards for the most part and it's an Elite series CEB other than a couple BIM's The OMI I am using is actually a COIM but I couldn't tell you the version off the top of my head. The OP position is CC2 though not 2+ so maybe that has something to do with ...

desperado

Does the radio IP traffic cross any router or layer 3 switch before besides the firewalls?
Do you have each device with a different MULTICAST IP and UTP port are are they within the standard multicast subnet of 235.0.0.0?

desperado

Yes, MUPLed the COIM and I do have they defined as DCCM's Have tried them as T1R1 and T14R14 both scrolling and interlocking. No dice.

desperado

I have a Centracom console I have been piecing together and updating as I can. I now have 2 COIMs and got some DCCM's to go in the button and LED op position. I have a CIE, but I would rather stick with the Button and LED op for now at least. I like the look of it better. Now my issue. I can't seem ...

desperado

I assume that you have the dongle in both op positions. So a few questions. Is all the hardware plugged into the local switch? Can the second op see the First op computer on the network ( with it ping it)? Can the second op see the gateway (ping it)? The first OP computer is also the server for the ...

desperado

Yep. possible but VERY expensive. First option is Roci Cori modems for each console... second option, and only if you already have an ambassador switch is installing T-1 circuits between the two locations and adding the needed ABE cards to the switch to interface the CEB's that will aslo need moved ...

If you are hearing the transmitter in the repeater, then it's getting deep into the receiver section of the repeater. With those signal levels, first thing I would do is pull all the 214 and go to hardline with properly installed connectors. You mentioned superflex. If you are referring to LMR400/60...

Bill_G So, why didn't Fayette just change freqs? The logistics of touching every radio in the county aside, another channel may (emphasis on may since high band can be crowded) have worked better. We've run into similar problems with Trbo systems that get "interference" from co-channel use...

desperado

I'm always happy to lose bids like that, and then come in to play janitor a year or two later. Because that's what we do ... That's great Bill but how do you clean that up? Ultimately the Kenwoods will go in a box or on Gov-Deals and radios that are 100% compatible (Motorola gear) will be purchased...

Now, about the DMR in the APX radios. That was the original plan, but DMR and it's range and issues with interference changed all that. If you go grab an Ohio map, I will tell you a story of DMR. Find Fayette county on the map. Now find Licking County on that same map. Far apart, different area's of...

Well, it might not be quite that bad. But the little fish really want to play in the big pond. There is a reason that the development at Schaumburg goes on in a faraday cage.

Yeah, It's Motorola's barbeque and it does taste good as long as your not funding the purchase or trying to put brand X radios on their system. From the point of an integrator the whole Kenwood P-25 thing is a thorn in your side. You have the customer awe struck at the cost of the system. You have t...

Try programming the ham channels narrow and I bet the securenet will not work then. Need DES, not DES XL for narrow I believe. OFB is P25 only.

desperado

One thing to keep in mind with SNR. Going from wide to narrow didn't change the amount of noise on a frequency only the deviation of the radios communicating on the frequency changed. Since you are listening twice as hard for hanf as much deviation, the ratio changed. Filters did get narrowed but no...

OK, lets start with the basics and go from there. First thing, go verify that you have the channels programmed correctly..

So, when is the Motorola SE scheduled to come out and install it?

From what i understand the CP and CM 200's while being digital will not communicate with mototrbo equipment, only with other cp /cm models.
Te XPR7000 is going to be interesting as it looks to be build on the APX 4000 platform

Assuming that this is an ebay radio it's one of two reasonable possibilities. One is that you bought a broke radio that has had some failure in service by the previous owner and they just threw it on ebay to dump it (this is the preferred type of failure because the factory will repair it for a fee ...
