If those features do not work on P25 systems, the CPS won't let you enable them in such an environment. Something isn't configured properly. There is also likely back-end equipment required to extract the GPS data and present it to another system that can display it, I know of no consoles that will...

I have personally (recently) broken two RF I/O connectors on two separate R2600 monitors. It was due to using LMR400 type coax directly on the monitor with many connect/disconnect cycles in a very short amount of time. Same thing happened - Center conductor pulled out, everything broke. Sent them i...

jmfirefighter20

I always turn down the power or use a pad into the monitor....no exceptions!

jmfirefighter20

I should have gotten ambitious before I posted...... I took the screws off the RF I/O connector and the darn thing fell out. Looks like there is a little "ribbon" of metal that connects the center pin to the I/O unit, and it was broken. Took the bottom of the monitor off, and the cover of ...

Hello All, I have a "new to me" GD R2670 that I picked up a week ago. Came to me labeled "bad antenna port"....replaced the fuse and good to go. I've been playing around with a few Quantars and have found that it seems the RF In/Out Port is NOT putting out what it should be, and ...

I just looked R16 without radio management is on there.

jmfirefighter20

Yes it is quite frustrating! When I was told that in order to do P25 simulcast, we needed to purchase MLC8000's for EVERY radio on each channel. All the transmitters are GTR8000s, but we have two Quantar receivers floating around still. They said we couldn't tie the GTR8000s in via the IP connection...

jmfirefighter20

Wait a minute - What about the new comparator/interface thing... MLC8000... I know it has v.24 and analog inputs, might want to check into that. Somehow it interfaces to consoles via wireline, I can't imagine it isn't capable of converting P25 to analog. The MLC8000 seems like it COULD do so much, ...

I also got this when replying to a PM, FYI.

I remote programmed a moderate sized fleet of Quantars using RS-232 to IP converter boxes. Works slick with being able to program stuff remotely without visiting the site. Don't know if you'd rather build one or buy one, but here is an off the shelf solution that I use..... https://www.amazon.com/Br...

jmfirefighter20

What kind of head do you have now (W series or O series)? If it's W series, you're gonna have to piece the kit together as the O series conversion kit is NLA (I tried to order one last year and discovered that!). Also, you may need to bump your FW. If you currently have an O series, should be just a...

jmfirefighter20

There shouldn't be any addressing for the CIE. The COIM card in the CEB has to have a TDM address assigned to it in the database and via the dipswitches on the COIM card. The CIE-CEB wire needs to be plugged into one of the two terminations on the CEB card cage where the COIM is located. Termination...

A word of caution here on just randomly swapping cards. There is audio level adjustments that need to be at the correct levels. You need a audio level meter to be able to adjust these boards correctly. Poorly adjusted audio levels will effect both RX and TX directions. Best you have the technicians...

jmfirefighter20

What I meant about they type of transport method was what do you have between the CEB and the control station? What does the setup look like? You need to make sure the cards match exactly....jumpers, dip switches for address, -everything- when you are swapping cards. Sorry if that wasn't clear. I kn...

jmfirefighter20

Hello, The first thing I would do is change out the BIM module in the CEB. The BIM modules are the cards that slide in. You do have a spare, correct? If you have a pile of them, make sure you're using the right kind as there are several different board types. You can compare them visually and by par...

jmfirefighter20

I second that the XTS3000 may be an older radio, but they sure are a workhorse. I still have some in active use in my fleet, but the majority live as spares in the command truck or in the office for grab-n-go situations. They're not a pretty as an XTS2500, 5000, or APX, but they take beating and kee...

jmfirefighter20

I want to add that I thought I saw somewhere that 90uS is about the max that a receiver can handle before it starts having issues as long as the strength differential between the two (or more) signals is great enough. http://www.simulcastsolutions.com has some information on simulcast design and imp...

jmfirefighter20

AFAIK, the version of the V.24 cards does not matter. It's the SCMs that have the timing differences. I guess I misunderstood your question, and answered it as what seems to work the best around here for our particular system. You are correct, the 55uS I wrote is the launch delay in the Quantar itse...

jmfirefighter20

In my system we are running 55us across the board out of our Quantars on narrowband P25. Don't forget that you need to compensate for the 5us of additional delay with EPIC V Quantar SCMs (that is, if you have an EPIC V mixed in with older EPICs, add 5us to the older stuff) Portables and mobiles that...

jmfirefighter20

Here's one. This was mounted on the pump panel of a fire truck I owned. In the cab was a Syntor....I took it out when I sold the truck it was too cool to let go. The Syntor and this unit still work (even though it's not narrowband, it's still nice to hear this old worker running and receiving!) Anyo...

jmfirefighter20

I don't believe there is a way for you to adjust the duration of tones. I just read one of my XTS5k's that also has R20 firmware and can see no setting. I don't think it really matters the "duration" of the tone, as long as the tone pair is a valid pair for the radio. I know when I set up ...

jmfirefighter20

Rumor from my local vendor too is that the newer black cabinets (for the GTR, since a GTR won't fit in the current cabinets with the doors on!) can ONLY be ordered as part of a package with another item. You cannot order a cabinet separately. Anyone shed some truth on this? They are nice cabinets ho...

Yes the knob electronics from an A4 will work! However, if you are careful, you can repair the knob. I have had a few lock up and I've been able to repair them no issue. You have to take the knob flex out of the radio. Take apart the back of the channel knob assembly (watch the small detent ball bea...

We were using a set of the JPS NXU2A for a while with four wire full duplex tone remote on an analog simplex channel. They worked great, however they do have a hardware/software delay inherent in them which caused some issues with our voting system until we were able to get everything adjusted corre...

Thanks for the replies guys. I'll definitely look into these other products! I'm sure this will be another adventure. Even though it may take some more time to learn all the ins and outs, it will be time well spent!

jmfirefighter20

I could be wrong, but AFAIK I think you have to have a consolette to do tone remote with a Spectra, Astro Spectra, XTL, or APX. They are not set up to do tone remote if you were to take a mobile, mount it in a building on a power supply, and hook it up. I would venture to guess that you can remote k...

I just got ours set up today. I have an APX7500 high power, with the HKN6187B, appropriate check box in the CPS for TX/RX audio out, and going into our new TeleCorder, we have good TX and RX audio out. Make sure you're using a 2.5mm MONO plug. It works great!

I don't know what your budget it, but Zetron's MaxDispatch system is pretty good looking.

I've searched but can't seem to find a good answer as to if this setup will work or not:

High power XTL5k with O3 head, siren/PA amp, and NO DEK. Can the siren be controlled directly from the O3 head, like it could be controlled from a W9?

Bill,

The common factor for both links is the Fire Tower. The first hop goes from my water tower to the fire tower, and the second hop goes from the same fire tower to another water tower.

If I take some screenshots of the diag plotter, would you look them over?

Thanks

jmfirefighter20

Hi Bill, Both links are acting how you describe them, however the V/H is all wayyyyy up when the throughput goes down, but comes back near center when everything is running well. I just had a thought pop in my head that perhaps the issue IS a cable, and maybe it's a heat/cooling issue? The cables up...

jmfirefighter20

No, but the machine was in there for a while before the issues started. Bill, Both are Cambium PTP products....one is a PTP49600 and the other is a PTP58400 lite if I recall, I'm not at the office to confirm.....they are connectorized with external dishes. I'm not feeling very lucky, but it's really...

jmfirefighter20

I on the other hand am not a network guy, so bear with me as well! We have IP traffic if I understand what's going on with my system. Our analog transmitters (all 4-wire) go into RAD IpMuxes on either end of their respective links. Our P25 Astro Quantars go through RAD SPS and FPS devices on either ...

Hello All, Hopefully I can pick the collective brain here to figure out an issue I'm having with two of my microwave links. The first link is about 8.5 miles from my Water Tower to a Fire Tower on a hill. She's running in the 4.9 band and normally has an aggregate data rate in the 30-35 Mbps range. ...

jmfirefighter20

If you have another speaker I would try swapping it out first. If it still occurs then you know it's the wiring or box.....good ol' process of elimination.
