Work dmr/star free from your cellphone no radio required

For licensed hams only

Working on new project called Peanut. On the Peanut you can talk with ham amateurs around the world via an Android device or network radio. Some of the ROOMS are connected to DSTAR reflectors (REF001C, REF030C, XRF076B, XRF076F, XRF71L, XRF070C etc.) You only need an Android device to use DSTAR. Maybe in the future I will add DMR also.
Supported hardware

Any Android device running Android 4.x of higher.
Inrico TM-7
Senhaix N60

Supported OS

Android 4.x or higher.


Make sure you are DSTAR registered user to use the DSTAR rooms like REF030!! Nobody will hear you when you are not registered.
You need a code to enter the Peanut network. This will prevent not licensed Amateurs to use the app.

Check if you are DSTAR registered :

Supported radio’s

ehh.. The Inrico TM-7 is running Android and looks like a radio 🙂
Who is going to make the first analog hotspot?


There are local rooms like SPANISH, DUTCH, ENGLISH, JAPANESE, KOREAN etc. These rooms are in HD quality.
The ROOMS like REF030C, XRF076C, XRF070C etc are linked to DSTAR. You can make a QSO with your phone/network radio to these reflectors. The rooms are transcoded with AMBE3000 chips located around the world.


You can see who is online via the reflector dashboard:


The DSTAR transcoding between peanut and DSTAR is done via DVSI AMBE3000 chips. I received some free AMBE3000 devices during my development in BlueDV. Many thanks to:

Complete solution:
XLX reflector club :

Solution that need AMBEServer on Raspberry PI:

If you are new to DSTAR, the peanut project will give you a first impression in the world of digital HAM radio. The Peanut project will provide some reflectors but not all. If you want to make the next step, check out these nice ICOM radio’s ( ICOM ). If you do not have a local repeater, you can run your own hotspot ( DVMega, ZUMspot or MMDVM_HS) at home.

Things to know

You do not have to disconnect to change a room! Just select a room and wait 1 second.
Peanut for Android is using port 5678 TCP and 6669 UDP to the internet. it is NOT needed to open ports from the internet to peanut.
You do not need an AMBE3000 for peanut to do DSTAR. I am transcoding it for you.
Do not use Peanut to interlink other systems!
There is no iPhone version of Peanut. Apple does not support experimental projects.
Runs very nice on a TM-7
Do not drive and Peanut. Always watch the road!
Peanut does not run on T320 and other portrait screens. ( working on it ) You can also use Peanut on Windows with an DVAP. ( use an analog radio ) Working on new transcoder software that allows more DSTAR reflectors. I am not a company! I write code when I return from work and mostly at night.

Challenges now

The Peanut was build as a concept. I never expected this interest. Now I am facing the following challenges.

Rewriting the transcoder software so it can also runs on Linux in a datacenter ( now only Windows ). ( done )
Make the master more salable and run it on multiple datacenters to minimize the latency.
Android app is now written in C#. I am completely rewriting the Android app to Java now. This is a lot of work. 80% is done now. Writing the app in Java gives me the opportunity to add more features and debug better. The app is almost finished now and a few users are testing it. Hope to deploy soon! New features like, BT, PTT key learning, portrait mode support.

Thanks to Yoshi JH1TWX and Andre PD1AEU. Both spend a lot of time testing during my development.

Keep in mind.. It is experimental! I am writing this software for fun and have no commercial intentions.

Have fun experimenting!
