That was exactly what I wanted to know. Thanks!

Zack08

I worded the channel question poorly. I meant having channel 1 page in position A, channel 1 monitor in position B, and channel 2 monitor in position C. Can they be configured for something like that? I suppose I wasn't clear with question 3. Lets say I have a board currently tuned to 159, can I ret...

I don't have a Minitor II yet, but there are a couple things I'm curious about: 1. I don't know exactly how the chargers operate. Would it be possible to operate a II with the pager in the charger, but without a battery in it? Just curious if the charger trickle charges the pager, or if the charging...

Zack08

Probably older than what you're looking for, but I think the Maxtracs can do it as well. At least with them you can set up a bunch of different signalling personalities.

Zack08

This has me thinking..... Has anybody ever actually tried this on a low band or VHF radio? Since they arent exactly designed with radio in mind, I wonder how much RF noise is present on the output. I'm looking for a new supply for my desk, but I've been leaning away from switchmode supplies because ...

Are you scoping that, or is that just a multimeter reading? I've had a spectra do the exact same thing because it was receiving brief power fluctuations during the self test. It took me a while to determine that the radio wasn't at fault....

Zack08

Alright, you got me. I didn't notice the smiley until I actually got to that part of the sentence.

Zack08

and the same to you, sir!

I just finished eating. I'm stuffed......

Zack08

If the backlight is blue and not green, it is most likely an Elite and should read/write with PF56AFLX.

Have you ever used your interface successfully on other pagers?

Zack08

Did the radios work before you programmed them? Try to force the original codeplugs back into them.

This usually isnt a fatal error, I have always been able to bring them back.

Zack08

It is possible to change the PA, but unless you have experience with surface mount rework, then I dont recommend doing it yourself. Not only is the RF PA a surface mount device, but I believe it is also covered by a surface mount shield that you must carefully remove.

Zack08

Yeah, I wasn't sure what your level of experience was with this kind of stuff. I can tell you from personal experience that if you dont feel comfortable, its probably best to find somebody who does.

If you ask around, maybe you can find one of our members who would be willing to look at it for you.

Zack08

Yes, by PA I meant the RF power amplifier. I just looked at the schematic for the 388, and it looks like the RF PA, the audio PA and a 3.5v regulator are all fed by unswitched B+, so these are all possible culprits. The schematic shows that the 3.3V regulator feeds an internal lithium ion battery. I...

Zack08

Does the PA always have power running to it? I've heard that some radios with unswitched PA power will do this if the PA goes bad, but I honestly cant remember which radios this affected.

Zack08

How often does this happen? Do the emergencies always come from the same radio ID? Are there any other agencies on this frequency that are close enough for you to normally hear? Depending on your answers, I'd almost bet that somebody has a radio on your channel that isn't supposed to. I mean, how of...

Zack08

You might have better luck if you tell us what series of radios you're trying to demonstrate.

Zack08

You set up a signalling system, but did you create a call list? Its like F6 or F7 (cant remember which) and its where you set the tones that you want to encode.

Zack08

The deviation on the QCII tones is probably too high for narrowband, and its exceeding the bandwidth of the filters in the radio. Theres probably not much you can try. They might turn the deviation down on the tone encoder when they switch over, but I'd just switch that channel back to wideband for ...

Zack08

You're correct, nothing is THAT easy. You'll need to get someone (like ICM) to make the correct crystals for your frequencies, and then align the radio. You can't change channel just by adjusting the coils (if thats what you were thinking). And I have no experience with them, so I dont know how low ...

Zack08

I wonder how many more modes can be added to the radio before the codeplug gets too big.....

And will the RSS allow editing of modes above 128 (or whatever the stock limit is) without modification?

Zack08

For an IDEN unit, that thing looks pretty cool. (I think.) Very TETRA-ish.

Although, with a pricetag like that, I'm curious to see how popular it becomes.

Zack08

I program my sabers with a 1GHZ PIII laptop (edit: but running true DOS, of course) and haven't bricked one yet. I'm not necessarily suggesting that you should try it, I'm just saying that its possible. The sabers are usually very forgiving as far as programming mistakes are concerned. You can disco...

Zack08

Thats what I was thinking, but I wanted confirmation.

Thank you!

Zack08

I fixed the problem, but I'm still curious if the squelch is a softpot or not....

Zack08

Hey guys, I have a low band M3 that is having issues. If I leave the pager sit, sometimes the squelch will open up and remain open until the case is gently squeezed. Carefully turning the pager off and on does not fix it, and changing channels does not fix it, only a squeeze of the case. My guess is...

Zack08

No, the Daviscomms PPS uses either the parallel or USB ports, not serial like the UPI.

Zack08

Methinks Q50 might be your best bet. Check it to see if its always conducting and let us know what you find. If thats okay, maybe the coil is shorted somewhere. I dont know what kind of capacitor C50 is, but you could check to see if there is a short there as well. Q50 or its driver seems most likel...

Zack08

Edit: At the suggestion of one of our mods, I've started a new thread here

Zack08

To answer your first question: All the dummy module is is a metal and plastic piece with nothing but one jumper wire inside. Theres no reason to make a homebrew dummy module. Its just one wire......

I'll leave the rest of the questions for somebody else to answer.

Zack08

Does your spectra have the DTMF decoder board installed? (HLN6151A)

Zack08

I have the same complaint about the Advisor IIs (but otherwise I think they're nice pagers

). The Advisor Golds have a much louder alert, but I honestly dont know if they are still an active Motorola product line.

Zack08

I've wondered this, too. I always thought that it was so the people monitoring the channel didnt have to listen to all the tones drop, but could still hear everything else. Thats my guess.

Zack08

Be careful when using metal polish, as the particles in the polish might not be as fine as they would be in a solution designed for plastic. I personally use a polish that's sold for cleaning plastic motorcycle windshields. I don't know if any Motorola radios use lexan for their LCD windows, but if ...

Zack08

MDC600 is an option on my 1994 Spectra (A5, 6.15MLM), but I never used it.

Zack08

I have never seen the gallery because I never knew it existed! I'd love to see it back online.

Zack08

Do any of the buttons work? Does it beep when you press a button?

Yeah, youre right. What was I thinking?

Zack08

They're not constantly under vacuum, that's just how they test them for intrinsic sacety. I think they might draw a vacuum and see how high they can get it before one of the seals starts to leak. If it holds up to sufficient pressure, I think they give it the rating. .....but I dont know for sure, t...

Zack08

From what I have read, it doesn't really matter what the radio looks like, as their firmware is only set to work on the SouthernLinc system, which is supposedly pretty similar to the NEXTEL network. You cant put conventional channels in them, and they dont take regular RSS. I did hear that they make...

Zack08

Huh, thats cool! I always wanted to know what it meant, too.

It does work, I have done it to several bubblepack FRS radios and they didn't sound quite so crappy.

I have a GP68, but I never thought the audio was that bad.

Zack08

I think almost all of the trunking systems let you see which site a portable is transmitting on, but I don't know if you have to look at the voter panel or if it will come up on a console. (Edit: Doh! I'm thinking EDACS, I'm not sure what type of system you're talking about.) I would like to point o...

Zack08

I honestly dont know what a 1 05 error is, but did you try selecting the 2K memory option on the radio wide settings and then programming? Someone else can correct me if I'm wrong, but I dont think the big M still supports the saber series, so they will probably just laugh and return it to you if yo...

Zack08

They might have had a suitcase programmer for them, but I know there is also a DOS RSS for the VHF/UHF conventional radios. I think it is the trunked radios that are programmed only by a suitcase programmer and a MIB.

Zack08

Lucky them. Too bad Pennsylvania is stuck with OpenSky.....

Zack08

Keep an eye out for the stuff on ebay, too.

Hope ya get your equipment back!

...and the same from me. Drive safe everyone!

Sounds like somebody has a loose programming cable.... I almost freaked the first time I did that to one, but was surprised to find out that they are so easily revivable. Heck, I spent a couple hours one day purposely trashing codeplugs and forcing different codeplugs in to make the radio think it w...

Zack08

Does anyone remember which RSS option I have to change to disable MDC1200 muting on a particular channel. I thought that when I programmed the radio initially, it was selected on a channel-by-channel basis, but after changing the programming a couple times, it seems to be enabled radio wide. It mute...

Zack08

Program a couple frequencies that are higher in the band and see if they all give the FAIL001 or if its just on the edge of the split. Also, make sure your input voltage is good, I have seen some radios in other series unlock at their band edges if the supply was too low. I suppose it could be a cap...
