Re: ADALM-PLUTO (new DATV SDR)
Hi alls,
Please I've need information.
I have installed my Pluto PC ( I5 - 2,5Ghz - 8Mo Ram) on windows 10, drivers, extended frequency, last firmware (0,29), and I have a problem.
When I send carrier, I can saw on my spectrum analyser that the carrier stops during transmission (alls 2 seconds about, sometime 1s, 3 s)
It is a real problem to TX video stream.
What do you think about it ? (no others softwares run, and I have try to change USB port, same problem)

Re: ADALM-PLUTO (new DATV SDR)
Frank,
You don't say anything about what what software so we can't really help. In general all I can say is make sure you are using a good USB cable and a port capable of powering the pluto and have the correct drivers installed and have set up the virtual network correctly. Beyond that, we need more information.
I would start by eliminating the obvious. Does it work with other software? You say no other software runs? Also try an English OS Locale setting as sometimes non-English ones give issues. A good example being the French use of a comma for a decimal point or in DATV Express for example, problems reading the info from sources.

Hi Mike ,
Thank you .
I have try DATVEXPRESS 1.25 LP11 (from Charles) and 1.26 with UDP entry (from Evariste)
I use original Pluto usb cable on USB2.
I try with SDR#, Pluto run, but modulation is not very good (metallic )
Ok for . or , I try this evening.

Re: ADALM-PLUTO (new DATV SDR)
I see - I think your problem may be the capture device in DATV express or the codec settings. What exactly are you trying to transmit? Symbol rate, codec etc?

Mike,
I don't transmit anything, if you read my first message, the problem is already on carrier , after I find italso on video flux (I try to send a picture)

Re: ADALM-PLUTO (new DATV SDR)
I had red that, but just because you only transmit a carrier does not mean the software won't not work because its capture settings are incorrect. Get everything right and try it.

Re: ADALM-PLUTO (new DATV SDR)
Those didn't play in Chrome. It looks like you are not getting the throughput on the USB. You have set a very high bandwidth - I don't think the Pluto can do that much. Try something more realistic, e.g. 1 MS/s
Re: ADALM-PLUTO (new DATV SDR)
Hi Mike,
Also, I have changed computeur, but on W7, same problem
I have downgrade firmware 0.29 to 0.27, same problem
and I have replace original USB cable by an other, same problem.
On my Pluto bottom, it's write: PCB RevB
I am desepered....

Hi Franck
That's very strange. Maybe there is a bug. Did you try SDR Angel? At least that might narrow it down. Also remember what I said about locales.
