What is AMBE3000™.

Digital Voice System’s AMBE-3000™ Vocoder Chip is an extremely flexible, voice compression solution that sets a new standard for quality, high-performance speech compression hardware. The AMBE-3000™ Vocoder Chip is a DSP-based vocoder that provides exceptional voice quality at rates as low as 2000 bps. The AMBE-3000™ Vocoder Chip offers the affordability and mobility required by virtually all full or half-duplex mobile communication devices. Its superior performance and flexible design configurations makes it an ideal choice for commercial, consumer and military communication applications.

In other words. The chip can convert PCM audio to and from digital voice ( DSTAR, DMR and Fusion ).

You put your AMBE3000™ stick in your PC and make QSO’s via headset or microphone and speaker.
There is no need for an expensive digital radio.

What AMBE sticks are available?

I tested the following AMBE3000™ USB sticks. All the AMBE sticks do exactly the same!

I only support original AMBE chips from DVSI. Illegal AMBE chips will not work or not correctly work! Make sure you use an original chip from DVSI! 

What AMBE network products are available?

ZUM AMBE board

The ZUM ambe board is made by Jim KI6ZUM and is very dynamic. The board can do Serial, WiFi or Ethernet. You can connect an OLED to the board to see the status on the board. e.g. IP address and WiFi RSSI. The board does not have an operating system so does not need any OS patches etc. On the following website you can find more information about the board : http://ambeboard.zumradio.com

Portable AMBE Server

This product is made by the Japanse XLX Reflector club ( JA1COU, JH1TWX, JR1OFP, JA3IYX, JA4CFO, JA4CXX, JA4DQX, NW6UP ).
You can connect this handy device to your WiFi network and use it remotely with BlueDV android or Windows.  On the following website you can find a lot of very nice documentation about this device. https://reflectorloversclub.jimdofree.com/

I personally also have one. I connected the device with an USB ethernet adapter and OTG cable. Now I can connect my BlueDV Windows OR BlueDV Android device to it. Keep in mind that you can use one device at a time. You can not connect BlueDV Windows and BlueDV Android. You have to disconnect one of them.

You can buy the AMBEServer at : https://reflectorloversclub.jimdofree.com/shop/
