Hello Barry I've also got DMR running with the ThumbDV now on the software I'm doing (slowly but surely). DMR uses rate 33 mode on the AMBE-3000 chip. Exactly the same audio quality as Fusion DN (half

Alright. Thanks for being patient and helping me understand the problem, John. I figured there was something I was missing. The unfortunate thing is that it appears as though they’re doing the

The problem is that on the Pi3 the GPU clock frequency can vary, unless it is locked to 250 MHz, then reducing performance. There is a load of stuff about this on the PI forums. 73,

I’m not sure where you’re getting this from. The Mini-UART is clocked off of the “core” clock. The GPU is default off of this PLL. The firmware sets this speed to 250MHz on the RPi 2, and,

Jeremy, I think you’ve missed my point. The Pi3 now has /dev/ttyS0 where /dev/ttyAMS0 used to be without adding any overlays. But by default its speed will vary with the GPU clock, and will start

show how much I looked into this.. in that case things look much better, but I didn't actually use the chip dummy repeater loads now and no errors with the test script.

Need to find the right serial device for those pins on the pi 3 -- John D. Hays K7VE PO Box 1223, Edmonds, WA 98020-1223

The device name has changed. You'll need to change it in both of them: python AMBEtest3.py -s /dev/ttyS0 or AMBEserver -i /dev/ttyS0 -- Jeremy McDermond (NH6Z) nh6z@...

Jeremy if you want to play with a rpi3 hit me up offline and I can enable your RDP/SSH into mine to play around with. has a GPIO DV3000 on it right now.

my testing is not definitive I quickly tried to put it back on the GPIO ... one yes it needs more power 2.5a to boot and I gave it 3a with the DV3000 GPIO python AMBEtest3.py d 8 N 1 False False False

I just got a chance to check this out today after clearing some other stuff from my plate. I don’t yet have an RPi 3 (They should arrive on Friday and I’ll give another report based on that), but

Barry, The app runs on OSX and Linux (x86 or ARM) at this time. On the PC I use the internal sound hardware with a headset. On the Pi I have used an external sound fob (CM108) for sound (the Pi has

Greetings to all the newsgroups And ' possible to have the DMRDongle480 program to do the tests ????????? tanks

Thanks Mike. I have a DVthumb and want to run DMR on it. 73, Barry K6ST https://twitter.com/barrybettman http://www.linkedin.com/in/barrybettman

Barry, If you are asking about the DV3000 or the ThumbDV, then yes I have done this. I am in the middle of working on an application that allows one to use the DV3000/ThumbDV just like the

Has anyone been able to run DMR on the nwdigital? 73, Barry K6ST https://twitter.com/barrybettman http://www.linkedin.com/in/barrybettman

There have been some significant changesto the serial port (ttyAMA0 is now used for Bluetooth, and the new ttyS0’sspeed depends on the GPU clock), so probably not without some work. 73, John

We don't have one for testing yet, but there shouldn't be a reason why it wouldn't. I'd start with the PI 2 configuration.

Hi Bryan, John and all, Will the DV3000 work with the Raspberry Pi 3? Regards Graham G7LMF

We’re interested. I have three on order. There actually is a set of solder pads on the bottom side of the board to solder in a connector. That being said, it’s not really “manufacturable”
