We have been using a Dell Latitude for programming out CDM-1250's and minitor pagers. The laptop recently went in and had the operating system removed and reinstaled (win xp). The motorola software was the first and only software to be reloaded after installing XP. Now, I cannot seem to read or ...

Is there anything independent of the park brake switch? I want something more linked to the park circuit on the transmission. There is no guarentee that someone will set the park brake, but more than likely, they will remember to put it in to park.

Thanks

Searched, but could not find...

Does anybody know where I can find a park circuit or neutral safety circuit and wire colors on a 1993 GMC truck?

I am installing an opticom, and am looking for a signal to energize a relay to disengage the opticom and the other white lights.

Thanks

Something our department did for our ht750s was to take a piece of 3M scotchlite and run it through a laser printer. In the settings, choose a paper type that pulls the paper through slow for best results. We got pertty creative. "Watermarked" in the background was the apparatus number in a real ...

Okay,
I definetly understand that a a receiver will desense when a transmitter is working near by. But, would it still be able to pick up a 5 watt HT that is no more than 500 feet away? That might be a dumb question, but I really dont know. When we are operating in that mode, we are only trying to ...

We are also thinking about installing a second radio, but I know we have not thought of the interference issues yet. We plan on using 1 VHF 45 watt CDM1550 and one 45 watt GM300. Worst case scenerio would be 730 KHz separation, best case 955 KHz. 1/4 wave antenna separation would be 5 feet (on a ...

Thanks Coyote,

That was it. I dont need the HT750s to do anything with the mdc, so I didnt think to enable mdc in the signaling rx.

Does anybody see any problem with using 100 ms as a pretime? We do not use repeaters, so that shouldnt be an issue. It all seems wo work fine here in the station, I ...

Greetings-

I have a bunch of HT-750s and a bunch of CDM 1250s. I set my DOS auto mute on the CDM to 175. Everything works fine (the mdc on the ht750 is set to pre, with 100 pretime). The CDM mutes and IDs fine. Everything works great. However, I cannot get the HT750 to mute the mdc. No mater how ...

That is what I guessed at first. Looking through the channels though, The first 10 are all simplex, some have tx tpl and some do not. None of them show the symbol.

Quick question.

I have a CDM1250 with about 30 channels programmed in to it. Some of them have a symbol that looks like to vertical bars with an arrow in between them pointing to the right. What does this mean? I looked at the programing of the channels that have it and the ones that dont and ...

So, Just to be sure, what I need to ask for is a CDM1500XLS and I dont need a cdm1550 with any of the other numbers after it (sorry, Im not familiar with the various "options" of the 1550).

Is there a matrix somewhere that shows the different "options" from radio to radio and option to option ...

If thats the case, somebody needs to whack me in the head for not doing proper research.

Well, on average, what is the average price diference between the 1250 and the 1550? (VHF Conventional). I think we pay around 575 or so now for the 1250.

Hopefully I am missing something obvious here, or else I just made some major commitments which I cannot keep...

I can get my CDM1250 to decode plain ptt id from an ht750 and show it on the display. I assumed prior to purchasing cps/rib/cables/etc that if you were to press the emergency button on ...

Another question:
I was playing around with the ht1000 rss today and started looking at the QCII settings. All of our Minitor 2 pagers have tone frequencies of 701.0 and 1669.0. Why on the ht1000 can I only select 697.5 and 707.3, but not 701? I have Motorola "permacode active filters" that say 701 ...

We tried this same thing for a while. The only other potential problem is the possibility of not being in quarters when the door goes up. I suppose it depends on the neighborhood you are in, but I'll bet in some cases it would cause the Chief to feal uneasy. Or in a volunteer dept, a weekly tone ...

Might be a dumb question, but a quick search didnt return recent info...

What or who do you need to be to purchase the software for the CDM series of radios? Our department is wanting the ability to program our own radios from now on, instead of having the dealer travel out to all of our diferent ...

N5TBU,
Will this adjustment you mention also work for external mic in? We recently had a local Kenwood dealer install a firecom system to a TK-790. Even with its transmit levels turned all the way down, the Firecom system is overdriving the Kenwood. The Kenwood dealer (who is a David Clark dealer ...

I am trying to interface a "telephone style handset" (p/n RLN4756A) to the accessory port of the CDM 1250. The accy port provides floating spkr+ and spkr- pins. As far as I know, the handset has a common ground, mic high, ptt, and handset audio. I have all working except the handset audio.

The ...

I have got the pinout of the accy connector, I do not have the pinout of the handset. It appears that the handset wants a "ground" and a "handset audio" the accy connector does not provide handset audio. When I connect it to ground and spkr hi or spkr low, I get nothihng. What I really need is a ...

I agree.
I would have taken this to a more expierenced installer if I had known from the beginning that it was going to involve this. It originaly started out as just installing the radio with a remote head. I have done a bunch of "easy" installs. Then it evolved in to adding the handset to the back ...

I was given a big box of equipment to install in a new medic unit. I just opened it up and can allready tell that I dont have all the parts to get the job done. Im not sure what all else I nead, but, I was hoping somebody else here could.

They have included the following:

-CDM-1250, AAM25SKD9PW2AN ...

Hello All-
I have been asked to connect a DC 3800 series system to a CDM 1550. At this point, I have the 6 conductor cable coming from the DC radio interface box hanging out by the radio.

Does anybody have any pointers on getting these two interfaced? I want to interface it to the accessory ...

You might consider this as an option:

Since you are only using 11 of the 16 channels, you might program the frequency that you are expecting to hear the tones on in several places.

For example, program that one frequency in to channels 1,4,7,10,13. The rest of your channels fit in between.

I ...

Thanks for all the replys. It sounds like the length matters more than I thought..... To verify that ordering a longer whip will solve the problem, I think I will give it a try using a stick of stainless welding rod. If that seems to work, I will probably by the real thing.

-Thanks again
-Sonny

OK, this might be a dumb question to some...

I have been asked to install an AM/FM stereo in a Pierce. Because of where the customer "must" have the antenna mounted, I dont have a whole lot of space between the roof and the headliner, like 1.25 inches. All of the commercially available car antennas ...

Oh, forgot to mention, I have the VHF version, FTM15-3092L.

I have been told that you also need the correct programming PROM, then you can ground S2 and get things done that way. I too have several Fujitsus that I want programmed. If anybody out there has a EPROM that they are willing to lend, or willing to e-mail, then I can burn my own. I believe it can be ...

Something you might try which has worked for me in the past:

Tune a radio or scanner to the pager frequency. Page yourself and record the page received by the scanner using your computers sound card. Be sure to record it in somewhat high quality audio. I cant remember if I used GoldWave or CoolEdit ...

Hello all,

Is it nessasary for radios these days be taken in for "Annual Maintenance" or something similar?

I work for a volunteer department that runs about 1500 calls per year out of about 11 stations. Some radios at stations get used daily, some get used maybe twice per year. We have about 100 ...

Found something strange today.

Shortly after turning on my CDM 1250 (2 seconds or so), I pressed the Scan button several times. It dumped me in to a screen where it looks like I can change the channel spacing, and the squelch type for each channel. The changes never seem to be saved. On the left ...

Thanks for the info, its starting to make sense. But, in cases where there are both CPS and RSS for a particualr radio, Why do people tend to lean towards the RSS?

Thanks for the reply

-Sonny

Okay, Ive been reading this site fairly regulary for a year or two, but I have what might seem like a dumb question. I am starting to see people sayin things like: "Oh, that requires CPS, not RSS....".

What exactly is the difference between CPS and RSS? I know that CPS is typically newer. I have a ...

Have a question that hopefully somebody can answer.

I have a CDM1250 set up for QCII decode on one channel. When it receives valid tones, it alerts as normal. I also get the "Call Received" on the display. It wont go away until there is a keypress. I want it to be either self clearing or non ...
