Anytone Anytone 878 For Scanning Commercial DMR Frequencies With Digital Monitor

[JASII]

If I recall correctly, the AnyTone AT-D878U can scan a maximum of 50 channels in a scan list.

Is it possible to configure ALL of those 50 channels as Digital Monitor so that it will display:

Color Code Used

Time Slot Used

TGID Used

Unit Id Used

Or, he does Digi Moni only work in the VFO mode?

 

[Whiskey3JMC]

Yes, it will display all info you requested in memory mode as well as VFO mode so long as said channels are set to "DIG" channel type (Digital) mode

Be sure to set Digital Monitor to 2-slot.

That is great to know.

Thanks for the tip!

It dosnt make a good scanner as it will get stuck on certain DMR signals such as Motorola capacity plus. You then have to use nuisance delete if its a channel or manually skip past if its vfo.I also have the 578 which has the same problem. It cant cope with these signals and you may get intermittent audio with them. Its slow when scanning.

That is a great point. I am using it just for additional details like what Color Code, Time Slots, TGIDs and UIDs are in use.

What is the best way to program a button to be able to stop the scan on the AnyTone AT-D878UV when I hear something that I want to focus on?

When I turn off the scan function right now, it reverts to a different channel.

MENU > Settings > Radio Set > [Choose key & press duration (short or long) of your choosing] (Options 42 to 51) and set the key option to Scan (11). Personally I set my scan to "Key PF1 Short" which is the key below the PTT. Caveat is frequencies stored in your memory need to be assigned to the same scan list (consult programming guide in the 878UV CPS zip file for details) in order for the scan function to work in memory mode. Hope this makes sense

Pressing the scan key during scanning will revert the radio back to the selected channel on the channel knob. Pressing menu during scanning will revert the radio to the landed channel or currently active channel. This is a nice feature Anytone added a couple of firmware versions ago.

...Pressing menu during scanning will revert the radio to the landed channel or currently active channel...

It sounds like I need to update my firmware!

On kind of this same topic I monitor a local DMR Motorola Capacity Plus Single Site (TRBO) system, I have the freq, color codes, talkgroups and etc all figured and programmed on a motorola radio I use for this. Using my Anytone 878uv-ii+on the control frequency in vfo mode and dual slot monitoring the radio displays all the info such as caller radio id, talkgroup, timeslot and etc but there is no darn audio. Any suggestions?

They are probably using RAS Restricted Access System.. Only a digital scanner or PC with DSD can hear the audio. It might be encrypted in which case you cant hear it attall on anything.

I first cracked it on DSD and gathered the CC, TG's and etc then put that on some motorolas i have. It works great on the motorolas I programmed. I know it's not encrypted but you could could be right about the RAS, maybe the motorolas I have align with that somehow and the anytone does not, I do not know anything about how RAS works. Thanks for that idea.

you would be surprised, that it works on one specific station, with specific fw too, and is not motorola

On DMR radios, RAS is handled by the CODEC chip firmware. Its not an easy thing to modify (nobody has been able to properly) as CODEC firmware is encrypted. Its often reported that older firmware for some radios has RAS removed but Ive never seen that. Even the MD380 has the CODEC encrypted but in software. Travis Goodspeed found that the MD380 is entirely software based but encrypted. He wrote an emulator that runs on PC but you cant access the code itself as its encrypted. The Anytone radios can almost in some cases receive RAS badly but its too broken to be useful.

I understand talkgroup and TS are irrelevant when using DS monitor on a DMR system but how can I find the CC using my 878 and not a say SDR or scanner is that possible? I’ve been able to monitor DMR commercial single channel no problem but the trunking is another story haven’t gotten it to work with systems around me. One system I’ve gotten to receive get the receive icon and full bars but no voice prob due to the RAS.

You can get the 878 to display CC and TG from the options setting in the CPS. When using digital monitor mode, if you dont get voice then itll be because of RAS or similar. You will have problems with receiving anything thats Tier 3.

 

[BabaDude77]

Right it does display it but what I’m saying is how do you program the channel without knowing the exact color code. Say you only know the freq and that it’s DMR 2 slot conventional and you don’t have a scanner or SDR

I only program the frequency and use monitor mode to make it easy. The radio will display CC, TG and slot if you set it in options.

 

[BabaDude77]

Ok cool thanks I’ll try it

 

[vselic]

ras works on openg77 for example so stories about only scanners or pc are totally wrong.Even scan is not usually interrupted by cap+...
