EA5GVK with Zumspot AMBE Server...


Adam Liette
 

 

Hello all. I’ve seen references to using the various AMBE thumb sticks, but has anyone used the Zumspot AMBE server with their installation of EA5GVK’s image? I have the Zumspot device that works either via the network or USB, but didn’t have any luck when I tried it.

 

Thanks,

Adam, W8FLH

I setup one before, you just need to set it up using the configurator in the Zum website. Afterwards you just copy the created file to the included SD card, insert it to the ambeboard and you should be good to go

I had that part done, but I wasn't sure if there was anything special to do on the Pi. I selected the AMBE device, etc, but wasn't getting anywhere on DMR or other modes.

Can you tell me what do you want to do with it on the Pi?

I used the Zum Ambeboard as vocoder hardware for Analog_Bridge. So upon inserting the configured SD card (Ambe Server mode with IP address 192.168.1.230 and port 2460) to the Zum Ambeboard, I plugged the Ethernet data cable to the unit then powered it on. Afterwards, I configured the Analog_Bridge.ini with the following lines:

[DV3000]
address = 192.168.1.230                ; IP address of AMBEServer
rxPort = 2460                                  ; Port of AMBEServer
; address = /dev/ttyUSB0                ; Device of DV3000U on this machine
; baud = 460800                              ; Baud rate of the dongle (230400 or 460800) 
serial = false                                    ; Use serial=true for direct connect or serial=false for AMBEServer

Ok. I didn't know about that part of analog_bridge.ini. What I'm aiming for is to use the AMBE board rather than md380emu and be able to use the DV-Switch mobile app. It was my understanding that using an AMBE device would allow it to work better on D-Star, etc.

I also tried MD380emu before but I prefer the Zum Ambe Server as the audio conversion to DMR is like night and day between the two.

However, when I used it for YSF I noticed some popping sound in between transmissions. This does not happen when on DMR mode.

I do not believe that this is hardware related. Please note that the Zum Ambe Board was only introduced recently, so probably the Analog_Bridge software needs to be modified for YSF to work well on the new hardware.  

Thus, in the meantime I use Zum Ambe Server for DMR. And for YSF, I configured Analog_Bridge to use ThumbDV on serial mode.

In addition, additional network changes might be required depending on where you will use DVSwitch mobile.

If the Ambe Server is installed in the house, and you want to use DVSwitch mobile from outside, then you probably need to set up port forwarding in your router for the unit.
