Holy thread revival, Batman!

Does anyone have the pinouts for the analog (orange) connectors on the back of the ATAC 3K comparator? And which goes to which?

Could also use some guidance on how the analog side connects to the DIU and Quantar station. It's been forever since I've worked on this stuff.

Sent you an e-mail to your QRZ email address. I'm having massive reliability issues with Batboard right now. I did find this: SmartWorks Systems SmartWorks is a single-site trunking system that can support up to seven channels. SmartWorks has the following capabilities: • Designed for small system u...

So for a telephone interconnect, you need a "Central Interconnect Terminal" or CIT. The CIT contains boards such as the PLIB, PLIC, etc. It also has a shelf of audio transformers that convert the telephone lines into four wire audio for transmission over the rest of the system. It's its ow...

For anyone searching in the future:

f * 12 + IF = carrier frequency. For 900MHz units.

d119

Did you ever get anywhere with this? Same problem here. The equipment I have to remove passwords doesn't cover the Advisor Gold.

d119

I have some pagers that I need to determine the frequency of. Bravo plus, Advisor, etc.

These are 900MHz units. Does anyone recall the formula?

d119

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...

Anyone know if a 42-50MHz MT1000 will work on receive only at 39MHz? I'm having a hell of a time trying to modify the RSS to allow the frequency entry. Seems 40.0 is the absolute furthest out of band it'll allow the radio to program before the RSS simply refuses to allow entry. I tried like hell to ...

d119

RIA - Glad to help! Some of those TRA units were in fact two wire only to lessen cost for basic things. The thought was that there really would be no need to return tones or duplex audio back to a dispatch console or remote with something as simple as a conventional base station. These things were u...

d119

OLH generally refers to On Line Help.

d119

Garden State Battery also carries (or carried) them.

d119

You can define the band, etc. in the MSF 5000 RSS and make the change to UHF there. But man oh man, I'd just get a UHF uniboard rather than go through all that.

d119

If I recall correctly, the TRC option should only be enabled if the radio is in a consolette, and that consolette has a TRC board in it. It's a bit misleading. There are also jumpers in the radio that have to be changed around in order to get things like filtered audio, etc. It may be worth consulti...

d119

Only way I've ever seen to get voting information out of these things is with the CTI Products equipment. I wouldn't put any DIGITAC comparators in service due to high failure rates as they age (and I speak from experience). Your money is better spent on a JPS SNV12 or SpectraTAC comparator for anal...

d119

An EPIC is an EPIC is an EPIC. With certain exceptions, you can swap station control boards between Satellite Receivers, AstroTAC receivers, Quantars, etc.

Hi Larry

KOKOK!

d119

See if you can read it with GP300 RSS... Let us know what happens. I'm damn curious... I also wonder if it uses the European GP300 RSS... Those had displays IIRC...

d119

It appears that the noise floor on this machine is around -90 in the spectrum analyzer.

Do you work on these? Whats the ballpark cost? This is an amateur radio use unit, no profit made with it.

d119

OK. Ran the NVRAM clear and recalibrated. Still getting random signal level numbers. Checked against an IFR-A7550 that hasn't seen a calibration in God knows how long, it's reasonably accurate though. One thing I do hear a bit of is a sweeping carrier in the background of the demodulated carrier... ...

d119

Very good. I assume that is done in the SPF menu?

Additionally, I have ordered a replacement battery for the unit, where is that battery located and is it reasonably accessible?

Thanks!

d119

Considering the SSD functions identically to a magnetic drive, it should not be an issue.

d119

Picked up an R2660C on eBay for $575.. Made an offer and got lucky. Seems to work fairly well, but there are a couple of oddities I have noticed: 1. It seems to show a random signal level when nothing is being input. Doesn't show a frequency error when its doing this, nor a deviation. It measures si...

These connectors on the MTR 2000 are atrocious. On the MTR 3000, they were replaced with euro-type connectors. Disassemble the station. On the backplane, unsolder the stupid friction tabs Motorola put on there and solder 12" or so of four conductor telephone lead on there. Terminate the other e...

d119

Are you sure you have your timing set up right?

d119

It's not that Motorola screwed up on them, it's that Motorola has it's own non-standard tone plan for tone keying with Centracom. Simply set the DIP switches on the consolette tone remote control board for "Centracom" and it all lines up. However, not all XTL consolettes have tone remote c...

d119

Well more than likely you are using tone control to key the radio. Aside from an ACIM connection, if you are using that, there is no serial communication between Centracom and the attached radios. You need to program the number of channels you want into the first zone of the radio, and then program ...

Try a firmware update to re-write the DSP firmware if it is corrupt.

SNV-12's still chirp if the dip switch to disable it hasn't been flipped.

I put in a lot of the infrastructure in some of the small cities in LA County.

d119

I'm *fairly* certain I have that documentation either here at home, or at work. Thanks for the reference, I'll take a look through it.

d119

In the Resource Configuration screen of CDM, you should have "Frequency". You use "Frequency" to determine how many channels the console has access to, and what the names of the channels are.

d119

Very good. Well I would definitely not be using the Community Repeater manuals on it, as the backplane would be completely different. My guess would be as different channels are selected, different tones are encoded/decoded. For repeater service, you only need F1, so you should be good there. I woul...

d119

I don't think it was a community repeater, else why would the F!/PL, F2 control and guard tone modules be in it? Sounds like it was some sort of base station originally and converted to a repeater (RCB vs. RTB).

d119

Is it possible to set up a Centracom Gold Series B&L operator position as a remote op, similar to the way you'd do it with Gold Elite CIE's using a ROCI/CORI combo?

Something tells me it might be possible to use the CORI on the B&L position - does this make any sense?

d119

No, there isn't.

d119

Agreed - you can make this do exactly what you want with a little patience and research. Take your time and work through it, you'll figure it out. The MICOR is one of the most versatile stations out there with easy access to all of the necessary signals, like Bob said, you just need to find the righ...

d119

This really belongs in the infrastructure forum. I miss being able to move posts around. It should be as simple as hanging your ID circuit off the PTT line and running the audio output of the identifier into the audio input of the MICOR repeater. Those leads should be available on the back side of t...

d119

Interfacing *any* type of controller to an MTR 2000 should be as simple as following the procedures outlined for the given controllers spelled out on Repeater Builder. With few exceptions, all repeater controllers will interface to any given radio in the same manner. So while there is a procedure sp...

d119

When programming the MTR 2000 for external control, it should be set up in "Base" mode, not "Repeater" mode. You really should read all of the documentation on Repeater Builder about the MTR 2000 and interfacing it to an external controller. I gave you the link in your message ab...

d119

Holy thread revival, Sandra! 11 years!

d119

That is correct. The MTR 2000 internal controller supports very basic repeat functions, timing functions and identification functions. For anything beyond that, you will need an external controller of some sort. There is a plethora of information on how to interface repeater controllers to the MTR 2...

Has anyone ever used Vanguard Networks 6455 series routers for E&M over IP? Apparently this was a Motorola supported configuration for a system I decommissioned and the routers have come available for reuse. They were being used to backhaul remote operator positions over an IP network. Curious i...

d119

I came across this some time back and had to uninstall and reinstall the CPS to get rid of the problem.

d119

I would put a wire counterpoise off of the ground side of the antenna trailing along the ground and see what you get.

d119

You are about to realize that some signalling features that work over simplex channels with analog modulation don't work the same, if at all, on a P25 backbone. Most of those you identified will function in a significantly different fashion. Your department's technical and operational experts must ...

d119

Well lets first off not get terms confused. It's called X2 TDMA, not P25 X2... You're mixing flavors there. Don't forget about OBT radios, Karl.

d119

That survey is fake as hell. Motorola is not doing market research on friggin' Survey Monkey. Give me a break. Stop wasting people's time. It most certainly is not. Hahaha that jackass shows his true colors once again. I completed the survey and there were definitely some "Motorola-esque"...

d119

...meaning?

d119

Oh hey Larry! 1kHz is the tone used as a status tone with the ASTROTAC 3000 in analog mode. Much like SPECTRATAC uses 2175Hz, Harris uses 1950Hz, well, ASTROTAC uses 1000Hz. If you are voting in analog mode using the ATAC, I would expect a notch to be present. I would look at the wireline configurat...

d119

Thanks, this helps. I'll have to crack one open and see what the Kenwood core radio really is.

d119

Anyone familiar with the JEM Radio I?

I need to program in some duplex channels with PL tones, and a couple of 151MHz channels. Our units use the Kenwood core radio.

Spoke with JEM support, they didn't seem to know anything about doing any of this.

Anyone have any experience with this?

d119

If you walk away from the repeater, does the issue go away? It may be that you are just hearing low-level RF from the exciter of the station.
