DMR (direct voice) simplex setup

Recently I made a sota activation and managed to have my first DMR digital voice contact on a direct simplex frequency. See my activation report here.

Here is a short description of the setup which lead to the successful QSO on a simplex frequency.

Both of us used Anytone devices, but I am quite sure it can be done between any DMR device. I had to use the 2m DMR simplex calling frequency 145.375 MHZ since my self built yagi which I used for the activation is only resonant on 2m.

Here are the settings:

• TX frequency: 145.375
• RX frequency: 145.375
• Contact: 16777215. This is a contact which allegedly, based on my research, is a DMR standard for general contacts and is called "AllCall". It is important to include this ID in the receive group list too.
• Color code: 1
• TS: 1

For us it worked but of course all devices have so much different settings and options that you might have to play around a bit.
