DMR Radio / New Board: DMR Radio on Radio Preppers.
« on: July 31, 2018, 09:48:00 AM »
Hello.

We have a new board! I need to say that for prepping purposes DMR might and probably should not be very high on your priority list. We assume that during SHTF there would be no grid power, let alone any Internet service. That said, it does allow encryption, which is however illegal in normal times...

DMR has taken the amateur bands by storm, and for good reasons. It is an open source mode. Everyone can implement it into their radios. Although it was designed for commercial radio use, it does work well for amateurs, well enough anyway. There is a learning curve, but honestly, once you learn the vocabulary, it is pretty simple. What's the advantage? It is worldwide... You can talk to anyone anywhere there is a repeater connected to the Internet. Is it real radio? Well, only between the repeater and your handheld, otherwise, no. It's still better than network radio, which isn't radio at all and should be called something else.

In any case, it is hard to ignore DMR today. My take on it is that if you buy an analog radio, you might as well get a DMR/analog radio, since they all do both. So I decided to start this new board. Ya'll have fun now and keep it civil  ;)

DMR Radio / Worldwide DMR Users File for Retevis RT3S, MD-380, etc.
« on: July 31, 2018, 09:37:56 AM »
First post in this new category!

Since I am using the Retevis RT3S dual band DMR radio, I wanted to import all worldwide users into its database. I found the following site:

https://ham-digital.org/status/

Click on DMR User ID List, space separated fields (ID call name)

The format is not the same as what is used by the RT3S, though it is CSV, but the columns are different. I wrote a small Python program to convert it. The resulting file, which will be attached to this post, does import correctly into the Retevis software, and I suspect will work with other Retevis.TYT radios. I have not tried to insert my new file into the radio, but I don't expect any trouble. Stay tuned for an update and video!

I will update this file every few months...

So that would be 22:00 for me here in France. Maybe I'll listen on my MTR3b :)
Keep us all updated!

I agree. No doubt RG-58 is better, but you should not lose as much power with RG-174. I don't know about the characteristics of RG-316. I only use it because it is mechanically stronger. There is always LMR-240/UF...

Make sure you do not take any cell below 3V.

I used to use RG-174, but now I prefer RG-316, even though it is less flexible.

Morse Code / Re: Yaesu CW Filters

I think that will be true at the beginning, when everyone still has charged batteries... After a couple weeks I think mostly QRP radios will remain on the air, which means more CW rigs.
