Topics and Questions

Please suggest your topics for discussion and questions for future Monday Night Nets:
  1. How are you finding FreeDMR? Are you enjoying the new DMR Network?
  2. How are you accessing the Network, Simplex hotspot, duplex hotspot, or Repeater?
    What radios are you using?
  3. Is FreeDMR truly open? Have you tried more than one Repeater and Server?
    How do they differ? Do you like peer-to-peer architecture?
  4. How do you find the documentation for FreeDMR? Where do you find the best docs?
  5. Have you used Dial-a-TG and how do you find it works for you?

If there is an area of FreeDMR you have a question about, Please ASK. There are probably others with the same question.


Which are the best Dashboards?

There are many choices of Dskboards with FreeDMR. Each server has its own dashboards and then any MMDVM Repeater will have a PI-Star Dashboard. So there are basically two types of Dashboards, FreeDMR Servers type and the Pi-Star type. They are quite different in the way they present data. As to which is best is a matter of private opinion. I am currently using the FreeDMR-Australia Server so I have one sceen open on this and I am transmitting via the VK4RBA Repeater so I have it's Pi-Star Dashboard open on a second screen. For more details see: Dashboards Explained


FreeDMR has Many Servers

REMEMBER that FreeDMR has many servers to choose from (three in Australia) and each may be configured slightly differently. Each Repeater or Hotspot can connect to any of these servers world wide, can also be configured differently. Try to be aware of these differences. For example, FreeDMR allows you to configure Talk Groups as you see fit. (Where you have administration rights. For example, your hotspot.) There is no matrix to say what TG's are allowed or to specify a time slot.



In common usage kerchunk definition is, "with a sudden heavy blow or thump". (Wiktionary) For amateur's in general the term kerchunk means to key up the repeater to see if it is there. For amateur's in the digital world is means to open a User Activated repeater to gain service.

It just takes a few seconds on Push-to-Talk (PTT) button on the transceiver to user activate most repeaters, resulting in a kerchunk sound. Then the successive Push-to-Talk's will allow communication to occur until the timer expires which is configured on the repeater or the hotspot you are accessing. This is usually 10 to 15 minutes.
