Hello Simon, I had a play with the Beta last night, very nice. Continuum works great as does the horizontal audio waterfall window. Thanks very much.

Re: How To: Connect to Pluto via Ethernet (Network)?

Hi Ingolf,

 

I added a sentence in the description to make the issue more obvious.

 

Thank you very much for your hint.

 

Kind regards

Hi Ingolf,

 

I am glad you got it working. Your finding matches my description:

 

Update 3: A radio amateur had also problems, getting his Pluto connected to his Router. He was
using the default IP address 192.168.2.1. and tried to connect to a Speedport Router from Telekom.
It turned out that the Speedport default IP address range is 192.168.2.x which is in conflict with the
Pluto. The solution is to change either the IP address of the Pluto or assing a different IP address
range to the Speedport.

 

Kind regards

Hi all.

I promised to report my progress on this subject.

It now works as expected.

So, I received my Y-cable as recommended by Matthias. As Rolf commented, you do not need a Y-cable, just a USB micro to USB-A (f) adapter cable.
The USB to Ethernet adapter is powered from the Pluto via the Data USB port just fine. So i just left the Y-end open.
The USB to Ethernet adapter is a D-link DUB-E100.

I set the 

[USB_ETHERNET]
ipaddr_eth = 192.168.2.196

The PC was set to 192.168.2.10.
No joy, i.e. no connection to the Pluto neither via the internal info page (port 80) nor via SDRC using the standard port 0.
I also put a Ethernet switch in between the PC and the USB to Ethernet adapter. Still no joy.

In the config.txt under [NETWORK] I had the standard
ipaddr=192.168.2.1
ipaddr_host=192.168.2.10
netmask=255.255.255.0

I then used ZenMap (Nmap) to scan all involved ip-addresses. No ports were found at all.

I then changed the

[NETWORK]
ipaddr=192.168.0.1
ipaddr_host=192.168.0.10
netmask=255.255.255.0

and kept the 

[USB_ETHERNET]
ipaddr_eth = 192.168.2.196

And the PC at 192.168.2.10.

Now everything sprung to life!
Both the internal info page and the radio via SDRC was accessible.
Now ZenMap shows two ports, 22 and 80.
Setting up SDRC I used port 0 at first but moved to port 22 when finalizing the set-up. Both works just fine.
It works exactly the same with the PC direct and via the Ethernet switch.

The Lessons Learned from this is that the [NETWORK] and the [USB_ETHERNET] CAN NOT BE SET TO THE SAME SUB-NET.

I enclose screenshots of the ZenMap display and the SDRC Set-up window with my working conditions.

My next step will be to configure Port Fwd in my router to be able to access the Pluto remote via Internet.

I hope my experiences here may help someone else to make it working as well.

KiwiSDR Switcher and downconverter update

applewiz2000 <rob@...>
 

Hi All,
I recently got planning permission to put up antennas and decided to build a special kiwiSDR board to select what I have in mind. A bit more than that - the board has a 2m downconverter.
The 'Ukranian' transverter boards are no longer available, and in any case a basic receive converter is all I want.

The concept is it selects 1-of-4 sources with the BeagleBone outputs, configurable on the kiwi webserver. A buck power converter produces 5V from a 12V solar charger
Any comments, or anyone may find this useful? Small design changes can be made now, I will track the PCB next weekend.

73s, Rob

The spurii you see depend a bit on the settings of the pluto... Or settings in sdr console...
Pluto can be quite clean if you use a bit lower power and add another gain stage in between... And filters for the band you want to use it on.. In rx and tx path!! 

50 or 60 db below main signal with all unwanted signals spurs etc... is not easy
.... So.. Pluto is not to be used as a main station with a kw amp and big antennas... I bet other contesters will "want to kill you"... Grin... 
But with a much smaller amp (so those spurii are milliwatts or less)... Its ok i think... You should measure and carefully set the levels way way down
And... Settings in console (example tx filter and drive settings)... Is the main thing that may produce a clean (or clean enough) signal... Or a very dirty signal with lots of ghost carriers.. 
Set power out to minus 20dbm and add a 20db stage behind (example a skyworks 65017). To get a quite clean signal..with 0 dbm
Is much better as cranking up the pluto to 0 dbm

The TL:DR is "USB2".

The reason is the maximum bandwidth you can cram through a USB 2 connection. (AirSpy and AirSpy (R2) push the limits of USB 2 and sometimes get 10 MHz bandwidth without dropouts and without bitpacking. Without bitpacking 6 Msps is a better choice for reliability than trying to push it a little.

NOTE that you likely will not get 6 Msps through an Ethernet connected Pluto. 100 MHz Ethernet is a little faster than 1/4th the speed of the USB2 connection. (A USB2 to 1 G ethernet adapter would probably make it to 6 Msps. I've never seen one.)

It is only for my curiosity. Presently I do not have any use of larger Bandwidths except for using it to receive the full FM broadcast band.

Do you refer to QO-100 Simon? For any other application I beg to differ. Do the job? Depends on what the job is. I would not use a Pluto with an amplifier for any terrestrial use. The output is horrible.

And let us not forget that Pluto is very much an educational device which we amateurs have adopted.

 

Beats me why people spend many thousands of euro on Kuhne transverters etc. when you can do the job for far less with a Pluto and SG Labs after blaster.

The TL:DR is "USB2".

The reason is the maximum bandwidth you can cram through a USB 2 connection. (AirSpy and AirSpy (R2) push the limits of USB 2 and sometimes get 10 MHz bandwidth without dropouts and without bitpacking. Without bitpacking 6 Msps is a better choice for reliability than trying to push it a little.

NOTE that you likely will not get 6 Msps through an Ethernet connected Pluto. 100 MHz Ethernet is a little faster than 1/4th the speed of the USB2 connection. (A USB2 to 1 G ethernet adapter would probably make it to 6 Msps. I've never seen one.)

Hi.
When I read the data for the Pluto and the heart of the Pluto, the AD9363 (alt. AD9364) I see a specified Bandwidth of maximum 20 MHz.

https://wiki.analog.com/university/tools/pluto/users/customizing#updating_to_the_ad9364

When I look at the settable Bandwidth in SDRC I see Bandwidths up to 6 MHz.
Can someone explain this. Is there a catch somewhere, I do not see.
It is only for my curiosity. Presently I do not have any use of larger Bandwidths except for using it to receive the full FM broadcast band.

That's why an update emerged at some point, DAB+. It uses AAC codec. Somehow, the UK did not really switch over to this new concept and largely remained with old services on air.
Yup... perhaps the motivation was to avoid obsoleting all the existing receivers which didn't know how to decode AAC?

Thanks, all downloaded, great for testing. Canadian FM is a very different beast, some great Jazz.

Simon, here you go. 5 minutes (and 30GB) of the most uninteresting radio market in the US. Plenty of big signals, Low Power signals, HD signals and little room for DX. Which is what makes SDR's and DXpeditions so much fun! In fairness I hear the Euro dial is even worse. And, if I turn the antenna 45 degrees things aren't quite as bad.
