New to DMR & PiStar

Post by G1SCY » Sun May 12, 2019 8:52 am

I am an old ex RN submariner with a diesel soaked brain.
My background is electronics spent 24 years maintaining submarine sonars and further 20 years in MoD electronics on the other side of the fence so I am not a complete numpty just in case you think that any information imparted will be completely lost on me.
I left Amateur radio some 15 years ago as a lowly class B licensed amateur basically because I was pissed off with 2 metres.
I returned to radio last year bought some kit and here I am amazed what a complete transition.
When I left it was a world of old two letter G2s, then G3s and G4,s then the lowly class Bs G1s,G6 &G8s and valve kit
Then I return and the kit, radios with screens monitoring everything from signal strength to band width ATUs, hells teeth then they throw in digital radio what!!!?? Well OK they and still do had packet which never really enthused me.
So now we have Fusion, D-Star and the thing that I am struggling with DMR
I bought an Anytone D868uv brand new. Nice bit of kit. The nice man stuck the code plug in (Moonraker) and away I thought I'd go.
Oh no, I live in wet and windy Cornwall on the edge of Bodmin Moor nice as it is it doesn't like Digital radio very much that is there is not a repeater in site that I can access. See where this is going?
So Sunny Jim here bought the makings for a hotspot cobbled together the program, well not really downloaded it on to my SD card and after a lot of 'faffinf' about I have managed to get my PC to talk to the hotspot, thanks Alan Taylor you are a star, and now, I think have a fully configured dash board.
Now what they says
I'm sure its easy but not fully trained on using the radio I'm a little stuck
What I need is a good tutorial on DMR and hotspots or some one in Cornwall that is prepared to be fed tea or what ever their tipple is whilst giving me a bloody good verbal bollocking on the art of DMR and its workings.
Yes I trawled the web found lots and lots on code plug programming hotspot programming wifi configuring but nowt on how to use it all.
Sorry for wasting your time but whats needed is book that's starts not Once upon a time but First turn on your radio.
Thanks for reading. I will, like most things I have done in the past figure it all out.....eventually but life is ebbing away.

Fred,

Not sure who Alan is, but glad he helped out :lol: :lol: :lol:

DMR is not half as complex as it looks, but it does help to understand a little of where it comes from;
It isn't, and never was a ham invention, we've adopted it, much like we have adopted P25 and NXDN modes; D-Star and Yaesu Fusion have at least been designed with Hams / Callsigns in mind.

Moving a little deeper, DMR is specifically designed to make the very most use out of a small amount of frequency, consider this a money making adventure, if you can sell the same spectrum 100 times over - you make 100 times more money... so...

Lets take some terms and talk about each a little:

Time Slots - there are two of them, cunningly named Time Slot 1 (or just Slot 1) and Time Slot 2 (or just Slot 2). Repeaters (and duplex hotspots with two radios) are able to utilise both time slots, for mainly historic reasons and compatibility, simplex hotspots always use ONLY time slot 2.
On a repeater both time slots can be active at once, with two independent transmissions going on, with two separate conversations in full duplex, users communicating on Slot 1 will neither hear nor interact with users on Slot 2 and vice versa. (Remember what I said about selling the same spectrum twice :) )

Talk Groups - Think of a talk group, like a room, if you want to hear what is being said, walk into the room, now you hear the conversation, if you are bored, leave the room and/or walk into another one. Repeaters will hold a talk group for 15 mins of idle time, after that the repeater will drop it (so if the TG is quiet for 15 mins it will be dropped) unless the repeater has been setup to make that talk group static.
Hotspots will hold multiple talk groups for 15 mins of idle time too, BUT the last connected talk group will "stick" permanently, so that you have something to listen to. (This behaviour is network dependent - don't be surprised if you don't quite get this experience).
When you are venturing out for the firs time, start in TG91 is most likely to be active and there should be someone available to say hello.

Private / Public / Direct / Group
Depending on where you are reading it, you may see references to Private / Direct calls vs Public / Group calls. Your radio should differentiate between them, I tend to use Private / Group terms. I private call is a direct call to a DMR ID, a Group call is a call to a Talk Group. So what is the difference, well DMR works on DMR IDs, these are 7 digits long for ham use (the ham use of DMR is somewhat standardised) talk group numbers can be variable lengths - but essentially it all boils down to the same thing, a number. Call it private and you can calling an end user, call it public and you are calling a group (room) with that number.

DMR Reflectors - they exist, I am deliberately not mentioning them because they will just confuse you and are more limited in their use - learn the talk-groups and how they work - you wont go wrong with that.

DMRGateway - Avoid it when you are starting out, my best advice is to start on BrandMeister, it's a well featured network, it has plenty of users, get your head around how it works and you are set for wherever you want to go next. Once you really get to grips with it all, then have a look at the things you can do with DMRGateway.

Have I left stuff out - oh yeah, definitely, DMR can be a complex beast, start simple and add more in later.

Sorry Andy I did tell you I have a diesel saturated brain and thanks yet again.
I am happy with the concept, that is I understand the terminology and what what the different attributes are its not that bit that's confused me its the PTT bit of it
What needs to be set up for a QSL
Set up the zone
Set up the TG
TS 2
CC08
So I set PL7PL as the zone
TG9
cc08
TS2
and zilch cos Plymouth repeater doesn't respond
I have been trying to get into GB7PL Plymouth but
I live miles from Plymouth and supposedly it ain't a very responsive repeater hence the hotspot.
Now what
You see for what ever reason my brain starts to wander. My radio is using Moonraker and the hotspot config is for 434mHz so my hotspot is the same
Yep ok radio and hotspot are in sync I s'pose but whats the PC doing? Looking for GB7PL? Gawd knows see what I mean am I looking to deep into this?
but how do I use it?
Watch the videos from the American chaps(being polite) they are whizzo but don't really get what exactly they are doing
and that's it I need, no sorry I want to know what to do next.
Is there not a numpties tutorial that tells me ?

Cheers Fred;OK from what I gather, you really should not have your hotspot on the same frequency as a 'real' repeater, as if you travel with your hotspot to an area you can hit the repeater, you could cause problems.

Next, If moonraker codeplug is based off of the PHOENIX DMR in UK you need to set your brandmeister master server accordingly. In this way all the talkgroups the GB7PL has you can get in your hotspot, if you set your zone correctly.

To resoak your brain with more fuel, The 868 makes it easy to have a single channel for the hotspot (sort of),but if there are certain groups you want to listen to often, it is best to create a channel in your codeplug and then add it to your hotspot zone. The CPS is a bit daunting and the learning curve steep, but once you understand how one is built it does get easier.

And yes, Andy IS a STAR!

Hi Kevin thanks if only I knew what you were on about ;)
Sorry just read that I wasn't meaning to be rude I just don't understand what the brandmeister master server has to do with what ever
My codeplug is set to 434 mHz my dash board is set to the same
I want to know how do I use the `hotspot to get out there please.
GB7PL isn't on the same frequency as my hotspot.
Do I tune the 868 into 434 MHz?

Using a hotspot means you do NOT directly access a DMR repeater. Presuming you are correctly configured with a DMR ID, and have specified a BrandMeister (I'm presuming you are using the BM system) Master in the configuration -- picking a talk group routes traffic to the BM Master which redistributes the packets to any other hotspot/repeater that is configured/active on the same talk group

The Color Code you configure has to match that of your hotspot -- it doesn't care what some other repeater uses for color code.

From https://gb7pl.uk/
Please be aware there are NO static talk groups on either time slot on this repeater. All national/international working should be done using reflectors when possible.
So, unless someone has activated a dynamic talk group on the repeater, and you are using the same talk group via your hotspot, there will not be any repeater activity.
TS1 TG9 should be used for local QSOs - this channel will act like a standalone local repeater. Hotspot users can use BrandMeister TG235228 to join QSOs on this channel.
So configuring your radio for talk group 235228 via your hotspot should activate the repeater's TS1 TG9 (local) traffic.
By default, this repeater will connect reflector 4400 which is TG2350 (UK wide). Most UK repeaters on the BrandMeister network will have this talk group connected by default.
And for this, you would configure your radio to talk group 2350 via your hotspot. You shouldn't need to be concerned with making a reflector connection if BM has a dedicated talk group that maps to the reflector.

I don't know what the programming software for your radio looks like -- the following are exported from my Tytera MD2017 (there is no export function for my MD390).

Channel information page for just BM WorldWide. With some study one should be able to map the fields in the image to the first "line" of the above table.

Finally, how my hotspot Zone information is configured. The MD2017 is nominally a dual-band (though single receive; activity on one band blocks the other -- not the most useful for DMR work, but passable for VHF/UHF FM), hence the A and B groupings. I have Mi5 Statewide 1 and 2 configured as BM Static groups, so they always come through the hotspot, while US Nationwide is a dynamic group. So, since Nationwide and both Statewides are in the same zone, If I have the radio on the channel "DV HS US Nationw" and someone keys up Statewide 1 I will hear it -- but to reply to it I need to rotate the channel select to "DV HS Mi5 SW1" (NOTE: that behavior may not be directly from the Zone, but may require the contacts and/or channels to be listed in the same "GROUP")

Thanks but in a word Struth
I'm even more confused than before
Why does everyone keep on about Brandmeister.
I was told I had a Moonraker code plug

Per https://www.moonraker.eu/blog/anytone-a ... code-plug/ that code plug (or one for other radios) contains information for connecting to in-range UK repeaters (channels/zones/contacts). Unfortunately, the moonraker site doesn't explain what the "extra goodies" consists of. You also have to have YOUR DMR ID programmed into the code plug.

You stated the nearest repeater is out-of-range for you, so you obtained a hotspot.

To use the hotspot you need to have suitable channels/contacts/groups/zones programmed into the radio code plug so that the radio talks to the hotspot.

(For the most part, a "contact" equates to a "talk group" when the contact is a "group call" type, "private call" type is more individual to individual. A contact can be assigned to multiple channels -- wherein a channel becomes a combination of frequency, time-slot, color code, and contact. Zones then become groups of channels. ).

The hotspot uses an Internet connection to pass digital communication traffic to a Brandmeister Master server. That server distributes the traffic to other hotspots and/or repeaters. If you are going through a hotspot you will be going through either a Brandmeister Master, or a DMR+ master (or one of the other DMR networks; note that talk groups on one network are likely not related to talk groups on a different network). For Brandmeister, you may need to register the hotspot -- https://brandmeister.network/

Your hotspot, presuming it is under your call sign, does not show up

Original business radio usage [think workers at a construction site] would obtain [lease] radios from some central provider who also has a repeater [or more], and is the radio license holder. While the provider may have half a dozen talk groups programmed into the radios, he may set up only one zone for the construction company with maybe two groups and individual contacts for each radio being leased -- the radios might have channels and contacts for everyone the provider leased them to, but only the ones in the currently programmed zone will be available to the users; remember, for business use, the end users are restricted to only volume, PTT, and channel select [from the channels in the zone] -- they never see any other groups or contacts. So the provider could lease radios to two different construction sites, and by using different groups and zones, the two sites never hear each other -- though they could conflict on repeater access. Talk groups, with color codes, are specific to the provider, not shared world wide

Grr my DMR ID IS on the code plug as it is on the Hotspot dashboard and I can assure you I am registered or what ever you want to call it where are you looking?
Please at te risk of offending all I am trying to establish is what my radio needs to be set to before I PTT

Fred, if you look me up on QRZ.com and drop me an email with your phone number, I can probably talk you through the basics.

For starters, codeplug is originally (I think) a Motorola name for a radio configuration. It’s nothing more than a file of radio settings and channel info.

A Zone is your personal group of talkgroups and/or FM channels. It can be called anything you like, ie South East, local FM Rpts, etc. It is only used to help you find the appropriate talkgroup or FM channel.

A talkgroup is a virtual radio channel, it is created on the fly by someone pressing their PTT. The system works by numbers, the UK wide calling group is 2350, you can call it anything you like in your radio. There are some short cuts to talkgroups in the form of reflectors, for instance sending a call to 4400 will fire up a repeater on talkgroup 2350. When using a hotspot they are irrelevant, although you will sometimes hear mention of “listening on 4400”.

Brandmeister is a network in much the same way that Vodafone is. Provided your hotspot is configured correctly it’s just a case of using it, although being able to log into the web page for Brandmeister does give you an insight into what is happening and allow you to set and remove static talkgroups for you hotspot. Static groups are present all the time, a dynamic one only appears when you TX and clear when you send a call to 4000 (usually programmed to one of the buttons on your radio). Dynamic groups clear after 15 mins of inactivity.
