Here is a hpe file for the DMR-MARC repeater K1DMR in Atlanta, it follows perfect, so you can see how i programmed it

Thanks,

I can't find a difference in the way I did mine. I'm not sure why I can't hear it.

I did find that I needed to enable the service type. That got rid of the "No Saved TGIDs" message, but it's still not receiving anything.

I would love to see ALL the digital modes eventually make it into the X36 line, including the Amateur Radio modes. Since these modes are conventional modes, and not some complicated trunking or multi-channel (or multi-slot) modes, it should be real easy (and fairly cheap development wise) to add.

Fusion is 2-slot by default. It can be run in single-slot mode for higher fidelity audio. Scanner decoding would have to be able to select the proper mode.

FTM-100/400 in AMS mode do that on the fly. Must be something in the data stream that the scanner could use like the 100 and 400.

It's the stock antenna. I've tried switching it out with no effect.

Poor decode of DMR Simplex

Grateful to anyone who has mastered the settings for decode of DMR simplex on the BCD436HP.

I'm getting very poor and unreliable decodes on VHF and almost nothing on UHF. This is testing using my own DMR handhelds, so signal strength isn't an issue. Decoding DMR Repeaters Conv and Con+ are problem free, other than the many false positives on TGs that has been posted before.

The best settings I've found so far are FM Modulation and Digital Threshold Level set to the lowest setting (5). Wait Time is set at default 400ms. Any ideas?

No, there are no "slots" with Fusion. It is not TDMA. There two different modes that are framed differently concerning voice (wide and narrow) bits, error correction, and data, but nothing as complicated as TDMA...and certainty no multichannel or trunking stuff. Pretty simple mode. Should be easy. There is also a data wide mode, but I doubt that would be practical for scanning.

Replay DMR One-Frequency missing slot info?

Running RC 3 on my BCD536HP listening to a One-Frequency system in ID Search. During replay mode, I see the talkgroups displayed, but the slot info isn't shown on the replay screen, although it's available when listening live. Is this a bug that can be fixed before the final release?

[I've always hoped that the displayed date/time would be changed to reflect the replay time stamp, but that's an issue for another thread.]

I'm in the process of pitting the 436 vs. the TRX-1 as mentioned in other threads. I see speed and better software as a virtue of the Uniden, and overall audio quality as a virtue of the TRX. So far.

One thing I would like to see is the ability to display information when the 436 (or 536) is programmed with conventional DMR. As this is a work in progress I take it that it won't always be necessary to program such systems as a one channel trunk in order to see TG and/or radio ID info. Whistler has this working well, especially now that their glaring Slot 2 reception issue has been repaired.

Both scanners do very well with the 2 Con+ trunked systems I have in my area. I've historically been much more of a Uniden fan than a GRE/Whistler fan so I'm hoping that some work on the conventional programming will come to be.

Phil,
You're right in that Fusion is not TDMA, but it is FDMA, which allows for simultaneous 6.25 kHz voice, and 6.25 kHz data "slots" in one 12.5 kHz wide standard voice channel (VD mode, also known as DN). That's how Fusion sends the extra error correction, plus the location (GPS) data at the same time you're talking. In the voice wide (VW) mode, it's only one 12.5 kHz digital voice signal, with minimal error correction, and no location info, and in data wide (DW), it's 12.5 kHz of data, right now only used to send pictures from the camera microphone.

That's still wrong FDMA dose not slot anything it is just a fancy term for conventional operation (1 talk path / frequency)

I thought we already had this. I just program the frequency conventionally and leave the Alpha Tag on default and I get the Color Code, Slot, TG and RadioID. Or is it something else you're talking about?

CAP DMR

Been doing the Search as instructed byUpman on this type of Dmr. I have a local electric company that
use the trunk/cap DMR systems. However, when in range of their transmitter never receive a cc or slot on any of their frequency in the fcc data base. Using the latest firmware beta and still only 2 or 3 second data bursts.

Have good result with other favors of the DMR upgrade except for the latter.

They have 5 frequencies in 151.000 to 159,000 MHZ Range. Any suggestions is greatly appreciated.

CF4M(Yeasu) is too limited. It's really only used by ham radio. Most scanner listeners are not interested. If they were, they would be hams and buy a Yeasu radio and talk on it.

OpenSky was originally launched in 1999 if I am not mistaken. There are only a handful of systems remaining. Most that are using it are likely planning on moving to more modern radio systems. All the open sky systems in my area have already moved to either P25 or MOTOTRBO. I can't imagine enough ROI to develop.

The only major system that uses OpenSky is the state of Pennsylvania, which is transitioning to P25. No need for OpenSky; likewise, TETRA (as mentioned by a previous poster) is not used in the USA except by a very few experimental systems. It is commonly used by public service agencies in Europe, Asia and some Latin American countries (like Mexico), but is usually encrypted. I doubt that Uniden is pursuing that digital format because they would have few potential buyers.

Well said both of you. Dead on. I believe Milwaukee WI or Oakland MI (or maybe both) uses OS as well. But almost everyone who has tried it has abandoned it for better modes. Those two users, if they stay, are not enough to justify the R&D required. IOW, as was very accurately stated, too little ROI.

That's still wrong FDMA dose not slot anything it is just a fancy term for conventional operation (1 talk path / frequency)

No. Frequency DIVISION MULTIPLE ACCESS is a frequency-sharing mode. It's just twisted by many people to mean conventional radio.

The difference between TDMA and FDMA is that the division is done in the TIME domain or the FREQUENCY domain. TDMA shares the frequency 1-2-1-2-1-2-1-2-1-2 and FDMA shares it with one user using the upper half of the frequency and the other using the lower half of the frequency (for 2-slot FDMA). For a 12.5 kHz wide FDMA transmitter, each user uses 6.25 kHz of the signal.

Many satellites transmit in FDMA mode using many slots.

Are you actually able to get the RadioID on a 436? I get the CC, Slot, TG but no sign of the RadioID anywhere. Unless I'm missing something that seems like a gap that needs plugged in a future release.

I wonder if scancapecod means the ability to get all this info IF an Alpha Tag has been assigned to a channel, and not just when its been left blank/default? It seems unusual having an Alpha tag field but then not be able to use it if you wish to see the TG info etc.

So I too would like to see this feature added...perhaps having the ability to alternate the display between Alpha Tag and the TG/RadioID info.

 

[KC1UA]

That is pretty much what I meant, although at the time I posted my remarks I was not aware that leaving the field blank (which I assume you mean by default) will afford seeing additional data. I'll give it a try today and see how it looks.

I haven't been able to leave the alpha tag blank. I've been using ARC536 to clear the alpha tags. kikito, Does default mean Channel 00001?

One Voice DMR

Does any one have a working file for one voice I can not get my 436 to work on DMR to save my life don't know if its me or what.I am getting to the point of giving up and selling scanner. If I go to the search I hear control channel fine just not decodeing when programed in.
