TG91 is going 24/7 world wide.
I use my own hot-spot a Pi-star hat on 70cm simplex.
I also use wiresX c4fm but not as busy as this TG91.
Many will say it's not real radio but i have had some good funny conversations on it so far.
Going to look on brandmeister and load some more talk groups when i get the hang of the programming side of this radio.
Plus i have a small power brick thingy i can plug the hot-spot into and put it in one pocket and linked to my phone in the other pocket and go anywhere with it.

Don't understand the bit you put in your last " or a simple 'CQ [TG/TG name], [YourCall] standing by'"..
You have to be in a TG you can't call for a TG.
You can qsy to another TG if you have them programmed in and want a longet contact say with a friend.

Sorry but i don't think you have ever used DMR.
You can't pick a qsy frequency.

We have done some experimentation using DMR on 446 here in York.
I have several DMR radios, my favourite being the Baofeng DM-1801 with the custom OPENGD77 firmware installed..

We found it the audio to be very clear even when the signal strength was very low.
I was able to talk to someone who was around 3-4 miles away on 1 watt of power, when I switched over to analog the signal was too weak to be heard.

In order to avoid confusion and interference, we decided on channel 10 to be the defacto DMR calling channel instead of channel 8 (Analog calling).

The only issue with DMR is with any digital mode, there is a sharp drop off point between usable to becoming unusable, with analog it is more of a smooth gradient as the signal gets more staticy/weaker.

Also I suggest we all use colour code 1, timeslot 1 and talkgroup 1.  Ideally all radios should be equipped with monitor mode (To disable colour code/ts and tg filtering) although I know that not all DMR radios are capable of full monitor mode hence the 1,1,1 solution.

I hope DMR gains in popularity, however the only other factor that limits DMR on 446 is the availability of accessible mobile radios. A CRT-SPACE U can be bought for around £60 whilst a Retevis RT90 costs approximately £300 leaving most to only experiment with handhelds with lower power or risk investing into a more expensive set which may have limited activity (Although they can be used on FM too.)

Danielle
I think you have your wires crossed here.
The post is about DMR but it looks like you where using PMR.
If you can get on DMR then you can get all round the world not just 2 or 3 miles.
Hope that makes sense.
Oh and welcome to the forum.

Hi Alan sorry about it, I didn't describe what I meant! I was referring to using Simplex DMR on PMR446, communicating directly from handset to handset not using the Amateur DMR network such as brandmeister repeaters or through the use of hotspots.   We would program the channel as a digital channel rather than analog but simplex not using a repeater network.

My mistake I am still getting used to this site!

And thank you.
