It's spring time, and that means it's time to go through the parts room and make room for the new round of Motorola parts. Unfortunately we have +30 years worth of parts, and I have no clue what half of them go to. Does anyone know if there is a Motorola database somewhere that breaks down what mode...

jwwissman, I am very confused by your post. Narrow-banding, if done properly, should have no effect on your transmit or receive wireline levels, or the operation of the SNV-12 voter. When you program a receiver or base station for narrow band, it should automatically adjust the wireline levels to co...

We are currently using a pair of old Motorola R-1034B Control Line Test Sets for measuring line levels, injecting tones, etc... They are showing their age, and I was curious if there is any newer test equipment available today that is up to the job. What do you use? Hopefully whatever is available t...

Wile E. Coyote

1. Has anybody voted a narrow band with a snv-12 voter? Yes 2. Did you use status tone from the radios? most of ours use status tone. Some use COR via E&M signalling through a T1 3. How did you determine your levels for audio? See section 4.6.7 in your SNV-12 Operations manual. We inject a sign...

Have you thought of wiring a PNP transistor in line to invert the signal? There is a great article about how to implement them here:

We use several NXU's with no issues. However, I have to say it... The NXU only creates a link as strong as your network. That is why we only use the NXU on non mission-critical systems. Sure, everyone's IT department says that they have a rock-solid system. In reality, most are not stable 100% of th...

Pat, The tech at Raytheon did say that the LED would look dimmer if the voltage started to sag. I have replaced caps in 4 more voters since my last post - ALL of them tested marginal (around 20% rated value) or poor (>20% rated value). I had one 100 uF cap read 5 uF on the tester. It's standard prac...

Thanks 35echo. For a second there I thought it was going to be complicated :lol: Okay, so maybe it is a little over my head. I don't think I can justify purchasing an eeprom burner just to hopefully get a few radios going again. Although part of me would love to do it anyway just to say I did it. Th...

Steve, Most of the CDM's we see with this problem have a bad flashrom. Especially if it has an Atmel AT49F040 for U121. We replace them with Atmel AT49BV040B which is what Moto uses on the new boards and it fixes the problem. Regards, Allen So if you simply purchase an Atmel AT49BV040B and replace ...

We observed intermittent staticy/hissy TX audio and tones from the console and all sites. Eventually the LLGT was delayed or missing all together. Apparently the -12V supply is key to some of the audio switching circuitry in the rest of the system. As the caps go bad, the -12 rail will begin to sag....

After battling some odd audio problems with one of our older SNV-12 voters, I managed to troubleshoot the problem to the Power Supply Module. When I called Raytheon tech support, they identified two capacitors in the -12V circuit that have been known to go bad with age. The next time you service a J...

Thanks RFguy, I eventually found the new planner, but it does not describe how GPS location updates play with voice on MotoTRBO. For example, can a MotoTRBO mobile have a voice conversation on time slot 1, and still be able to send GPS data using time slot 2 at the same time? I just need to sit down...

Wile E. Coyote

All of the planners I am finding online are from 2009. Where can I find the new one?

Wile E. Coyote

I have some XPR4550 radios that I am using in conventional, and we were thinking of upgrading to a digital format so we could take advantage of GPS location updates. Before V 1.07 firmware, you could only have a max of 30 to 40 updates per minute per channel. This is far too slow for our needs and a...

Wile E. Coyote

I have seen a Maratrac used as a base station once a long time ago. You are right, they do not readily provide COR. They found a spot on one of the PC boards to tac a wire on to and ran it out of the housing through a small hole that was drilled into it. Unfortunately I do not have documentation for...

Wile E. Coyote

It's also possible for the accessory pins to bend and short the speaker audio to ground, heating up the audio amp to the point of nearly burning flesh. Make sure all Accy pins are straight and any external speaker is not shorted to ground. I like the idea of monitoring the standby current on the ben...

This post claiming there is a Virus in these modules is untrue - There is no virus in any of our products. Firmware changes are not viruses. I / we / Whelen / would like to see this corrected to not improperly inform your board members. You are correct, it is not true. We found out some time later ...

Wile E. Coyote

The ones we have are the 18 wire WeCan Controller GEN 2

The more I think about it, it's probably a firmware writing screwup by Whelen and they didn't want to take the blame. Cowards.

Whelen overnighted GEN 3 controllers for us, and we are to ship back the GEN 2 modules.

Wile E. Coyote

Just to let you all know, Whelen has discovered a virus in the newer WeCan LED lightbar controllers. If you have noticed your lightbar not performing correctly, this may be the cause. They have corrected the problem but there are still a lot of controllers out there that may be infected. If you feel...

KE9GK, Thank you for your response. I am using a Centracom II Gold Elite. I have already upgraded the firmware once on this system to support newer OS and software about a year ago. I wouldn't want to do that again anytime soon. If I remember right, it cost us about $15,000.00 just for the firmware ...

For some reason when I try to do a radio check via MDC on the Centracom console, it does not work. (Yes, the radio is programmed for radio check). I have isolated the problem to the Centracom not waiting between keying the radio and sending MDC data. I have tried adjusting the Pre-Time Delay in the ...

By creating tow completely separate business entities, Motorola is basically building a firewall throughout the corporation. It’s almost like they expect one of the two businesses to perform poorly, and this way they can isolate their losses. But which one do they think is going down the tubes? -WEC

Just curious if anyone else is using Intergraph CAD software with their Banner interface to a Centracom Gold Elite to get alias information. Personally I was against this in the first place, but I was overruled by those who get paid more than me. Anyway, the most recent version of Banner software is...

If budget is of major concern, along with double vocoder (etc...) We found the Tait 9100 series base does the trick for about half the cost of a Quantar. Normally I would go with Motorola. But in a pinch it's not bad.

Thats what I thought. I managed to harvest a good codeplug out of a severely water damaged radio that was beyond repair by removing U0111 (8 pin flatpack), and putting it into the radio with the corrupt codeplug. When I powered up the radio, it worked great! I know that means the serial number was c...

I looked into FSB10112, and the connectors on the radio in question are good. I think I am going to try buying the ribless cable and flash the radio (I already have the flashing adapter) if nothing else works. I never did like how incredibly unstable/fragile the firmware is in these radios. I just w...

I wasn't sure where to put this post, hopefully this isn't too OT. If you are installing a Pocketjet 3 thermal printer in to a car, the manufacturer says to install a 5 amp fuse.

On top of that, The FCC is about to force us all to go through several steps of narrow banding – Eventually ending up at 6.25 channel spacing.
