From experience some of the Chinese cables that have a timing delay that use latent +12v on pin 10. I've noted that some MaxTracs and GM300s I have will have +12v on pin 10 when turned on. CDMs don't have this and pin 10 is always low. It is a long shot of course, because those Chinese cables are a ...

Thanks RFguy, much appreciated.

Anyone have the text the old SRN1397 for the XTS3000? As I recall it has to do with installing a plastic or rubber insulating material between the front cover and the RF deck shields, I know this SRN was superseded by SRN1473.

I've been holding off upgrading our fleet for a while now, hoping to hear more about the issue. I may go ahead and update one shift and see how it goes. Firmware 1.12.13 doesn't have that problem but the only way to downgrade is if you have the Depot software. I'd like to go to 1.12.17 due to the A...

The "squeal of death" is a known issue in older firmware and the solution is to upgrade to the latest version. A decent amount of our radios had the problem and Motorola originally didn't know what was going on. Eventually they just told us that a firmware upgrade should fix the problem, ...

I have a few NOS dealer trade in XPR6550's on my bench that intermittently will (without warning) begin uncontrollable loud squealing from the speaker after receiving analog traffic. Anyone run into this sort of issue? Some quick research seems to indicate this could be the result of a faulty volume...

EDIT: I remind you that by the FCC's own rules; itinerant is meant to define radio systems, that move place to place and maybe on the air for an indeterminate amount of time. Indeed, I just remember been told an itinerant license doesn't extend to fixed point operation. Simplex itinerant frequencie...

But is FB2I operation permissible on property you own? FB2I is used to define a repeater that moves from place to place. So yes, it would be legal on your property. An FB2I is not intended to provide a HUGE area coverage. But more of a localized repeater system for an event, or what have you. EDIT:...

Honestly, you'd be surprised. Peruse some of the itinerant licenses that were successful. "90.35A - Temporary communications support for special events". That's perhaps the vaguest thing I've ever read. This is the vaguest thing ever -- however its a valid use case for Individuals and Bus...

The other excellent thing about the CS site was the fact that; there was a separate section for other vendors.

There is no such emission code as 12K50FXE for DMR. The 7K60FXD and 7K60FXE are used for both repeated and simplex communications.

FWIW: 12K50 isn't even a correct prefix for 12.5khz channels; 11K2 is the 12.5khz channel prefix.

gatekeep

I'd like to interject that ... my EF Johnson 5100 scan's about 32 or so conventional channels relatively quick (with room for a plenty more channels in the scanlist). The primary difference here is I think with the speed of the embedded CPU in the radios themselves. It is quite possible that the pro...

As I answered you on the other site:

Pin 5 is common gnd for both logic and audio on the MaxTrac/GM300 (Radius) mobiles. You'd need to tie Pin 5 on the RJ45 to both 5 and 6 on the RJ11.

Hi. I'm looking to buy an older 4mb XTS2.5k for cost purposes. It has a flash code of: 520008-000510-2. The radio is currently on Host version 9.xx - will I lose FPP because of FPP/trunking if I use recent software? The radio has q52 and q53 but also has trunking. Last I checked, you can't bump the...

What voltage are you testing at? Are you using a regulated power supply set to the proper voltage as indicated in the test procedures? or are you using a battery? Testing using a battery can give you significantly different readings based on state of charge. Regulated supply at 7.8V (these are port...

I know that all radios are different and must be tuned differently. But roughly for a 5W UHF (R or S split doesn't matter), what is the nominal power range (measured at a service monitor or wattmeter)? I'm assuming the nominal range is about 4.8W. I had almost all of my portables except for one tune...

Does anyone have a copy of the MT2000 service manual or schematics? (Specifically for the UHF-H RF board?)

Will the NTN1177C chargers fit the XTS2500 batteries? I run all non-IMPRES NiMH batteries so thats not a problem.

So being the curious type, I purchased a MTS2000 (now I purchased it for parts so, I could careless if it functions) from the *bay that has the F01/93, now I know from experience, this typically means the radio is a brick. Now, from what I understand from SRN 1173, the toolproof error is generated b...

The decoder part already decodes some of the MDC codes to a textual context and displays them in the "MDC1200 Capture Log" along with a timestamp, however, in this area it still needs to be expanded a bit. But if you mean things like ID's, this is one of the things that I'd like to get eve...

So for my own programming educational purposes (both for C# and MDC-1200), I've managed to port Matthew Kaufman's MDC-1200 library to C# and add a nice GUI front-end to it. It's open source and located at: http://mdctool.codeplex.com/ So far it seems to work perfectly, though I seem to have an issue...

I have a curious question. I know how to properly edit MDC ID lists from a full keypad radio that's not a problem. What I'm wondering is, is how to enter A,B,C,D values into the ID field? I can add F but not A,B,C,D. How does one edit the ID list to add MDC ID's with a hexadecimal value in them (fro...

Just out of sheer curiosity, has anyone hacked or otherwise manipulated the MDF database on the Astro25 CPS?

When using a certain unmentionable software version R7, is it possible to increase the channel count beyond 512 (assuming one has firmware of R12 or beyond)?

gatekeep

I agree to keep the PM system. This is the internet, not someone's home, you need to know how to censor yourself. You have no expectation of privacy when your using someone else's website. As with anything, gotta know when and when not to open your mouth.

Thats what I was thinking, but would there be any draw backs to using the 470-520 ant? Tx Power Reflection and the such? I do have *some* freq's that are also in the radio that are in the 470mhz range.

gatekeep

Just a curious technical question, I have a UHF S-split (450-520) XTS, and a set of antennas one 438-470, the other a 470-520. I'm mostly transmitting at 460mhz (GMRS). Which antenna would be a better choice for use on the radio?

I was clarifying the specific circumstances for 4n6inv and giving insight as to why Mfire39 was asking in the first place.

Ya, I basically lost my cool when the radio exhibited 01/82 as I know it tends to be a PITA to clear on the XTS series. So tried a variety of different things, programming the radio right as it was booting seemed to work. I'm still baffled how this happened in the first place, its like CPS barfed an...

gatekeep

It is R12.00.03.

The weird thing is this thing out-right refused to write any other way. It was almost as if it was deaf to the world, don't know why writing it like I did worked.

gatekeep

*whew* Ok so I got my radio to write...

Basically to get the radio to write I had to tell CPS to write the radio before FAIL 01/82 appears on the screen.

gatekeep

I saved the last codeplug but, the radio won't write, CPS complains the radio won't acknowledge.

gatekeep

I have an XTS2500 with Fail 01/82...is there anyway to recover this with a good saved codeplug?

Lower frequency range. This is a 450-520 split radio, from what I was told, the clicking occurs only at frequencies below 465 or so. No the cold does not effect the radio AT ALL. Haven't tested heat, but, I would expect it to unlock at high temperatures. Again, the clicking is not all that noticable...

eng12ine,

Get your radio back from /\/\ yet? Anyone else have any ideas, I've been using this radio thus far, and aside from the annoyance with an open mic, this does not seem to cause any other issues. (i.e. No unreadable messages, No range issues (that I can detect), etc.)

Whats the flashcode of the radio according to CPS and according to the radio in service mode?

gatekeep

You could theoretically do it, and after they are switched force in a VHF codeplug into the UHF controller and retune the radio. But I'm not sure.
