peanut

Peanut is back. The latest Android version is stable and gives me more time to spend with my family. When I have time, I can work on bugfixes and features. Many thanks for all your friendly emails!!

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 ( 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

Supported OS

  • Android 4.x or higher.
  • Windows 7 and higher ( .NET 4.5 )

Access

  • Make sure you are DSTAR registered user to use the DSTAR rooms!! 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 : https://wb1gof.dstargateway.org/cgi-bin/dstar-regcheck

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?

Rooms

  • 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.

Transcoding

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:

DSTAR

If you are new to DSTAR, the peanut project will give you a first impression to 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 keep connected and select a room.
  • Peanut for Android is using port 5678 TCP and 6667 UDP to the internet. it is NOT needed to open ports  from the internet to peanut device.
  • 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!
  • Peanut is beta. Use it at your own risk.
  • There is no iPhone version of Peanut. Apple does not support experimental projects.
  • Runs very nice on an Inrico TM-7 or other network radio’s
  • Do not drive and Peanut. Always watch the road!!
  • The app does not work in the background anymore!!!
  • You can also use Peanut on Windows with an DVAP. ( use an analog radio )
  • I am not a company! I write code when I return from work and mostly at night.
  • DSTAR reflector admins can add their reflector when they have an AMBE3000 server with ThumbDV or DVStick30. Complete solution is from Japanese XLX team.

Challenges now

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

  • Spend more time with my family
  • Rewriting the transcoder software so it can also runs on Linux in a datacenter ( now only Windows ).  ( done )
  • Make the master more scale-able and run it on multiple datacenters to minimize the latency. ( working on. Tested now with 3 masters )
  • 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. ( done )
  • Write a Windows version ( done )
  • Add DMR 🙂 ( almost done )
  • Connect a radio to peanut Windows

Sometimes I post some new things or updates in the Peanut facebook group: https://www.facebook.com/groups/2017908268317595/

Thanks to Yoshi JH1TWX and Andre PD1AEU. Both spend a lot of time testing and admin the project.

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

Have fun experimenting!
