Experimenting with S912 octacore 16GB/2GB ram TV box-Spyserver

radiostationx
 

Hi all,
Experimenting with the idea of using an S912 armlogic TV box for spyserver.
I need some help here.
I used a redundant android TV box and installed Armbian Debian image on an SD card and the unit boots fine.
I then I followed these instructions to run 32 bit applications
https://forum.armbian.com/topic/4764-running-32-bit-applications-on-aarch64/
I have successfully installed rtl-sdr from github, and kalibrate.
Using an r820t dongle I can run kalibrate fine the program "grabs" the dongle and scans away..
The blacklist file (/etc/modprobe.d/rtl-sdr-blacklist.conf) has the following
blacklist dvb_usb_rtl28xxu
blacklist e4000
blacklist rtl2832
blacklist dvb_usb_rtl2832u
blacklist dvb_usb
blacklist dvb_core
blacklist fc0013
blacklist rtl2830
 

I then installed airspy drivers and spyserver from github and finally made spyserver executable.

All seems to be fine


BUT
When I run spyserver
SDR sharp says server busy, and server device says cannot wake device.

Tried all kinds of things in spyserver.config including starting over again and using several new spyserver installs but cannot seem to get this running.
Has potential as s912 octa-core boxes can be had for around $40usd complete with 3a psu.

Any ideas guys ?
Thanks in advance.
Re: Recording longer files

Patrick
 

Thanks for the tips Martin.

I've been using the "File Player" and the "Audio Recorder" plugins for quite a while.
The IF Recorder does not meet my needs as I want to record the full HF+ available BW (768 kHz or 660 kHz alias free).

I just installed the "Baseband Recorder" and it seems the good option is 'WAV RF64' ("WAV SDR# compatible" and "WAV Full"  being limited to 2 and 4 Go). The only downside is that this format is not compatible with SDR Console Datafile Analyzer, I was planning to use to analyze large overnight recordings ... (the test file I recorded does not appear in the list, thus I suppose its format is not supported).
Return to square one !

Thanks anyway for your kind help

Re: New SpyServer optimization in r1587+ #sdrsharp

Dave C aka Dave3825us
 

I installed spyserver Server v2.0.1700 on Raspberry pi 3b+. Using sdr# 1700 on windows pc. Running Airspy Mini on Raspberry.

I can not get nfm bandwidth higher than 11,718. I need 12500.  I see others have been able to do 12500.

On wfm, I can not get higher than 187500. 

Use full iq also remains greyed out and unuseable in sdr#. What should rtl_sampling_mode = be set to?

I also tried windows version of spyserver in sdr#1700 folder and same results. That leads me to think I have some problems in the spyserver config.


This is the spyserver config on the Raspberry.   Any help would be most appreciated.

Hi Gary,

You need to use an Ext-IO file which will allow the HF+ to work with HDSDR.  You can download it here:


Note there is one for the regular Airspy and one for the HF+.  Download it and copy it into the folder on your computer where HDSDR resides.

I should indeed give Linrad a try but I find it quite difficult to master ! (I watched many of your clips showing Linrad in action).
So it seems it is not possible to record larger files running SDR# ...  What a pity.

Download the ExtIO file from http://www.montefusco.com/airspyhf/ Copy it into the HDSDR folder. That’s it.

Hi there,

A single recorded file (full 768 kHz BW) seems to be limited to 2 Go ; this
means the recording won't last more than about 12 minutes.

Is it possible to record a single file during 30 minutes or 1h or even more
? (still at 768 kHz BW of course).

Thanks

You problem is that you can not currently connect to your RPi through the directly connected cable because neither end has been configured with an IP address. And in addition neither have routing tables configured, so there is no way to transfer data from the RPi to the PC or the PC to the RPi through the Ethernet cable. You have a physical cable connected, but there is no configuration telling the device how to use the cable.
You will get far better support for a RPi, if you really want to configure your device in this unusual way, by plugging something like "site:raspberrypi.org how do I setup with a direct cable connection" into your search engine of choice, or "connect raspberry pi to PC without router" or by posting a query on the raspberry pi support forums. https://www.raspberrypi.org/forums/
Or you could just set things up in a much easier way, you have three options as I see it:
RPi<-ethernet cable->internet router<-ethernet cable->Windows PC (this would be the default configuration for most people, you plug the cables in and everything just works)
RPi<-wifi->internet router<-ethernet cable->Windows PC (a tiny bit harder than the above but there is a idiot proof guide on https://www.raspberrypi.org/help/ )
RPi<-ethernet cable->Windows PC (you will spend a very long time trying to get this configuration to work as a beginner)

He can connect. He says ping works, although he has not said what addresses they have respectively to be sure.

RPi: ifconfig >spoo1.txt
PC: ipconfig >spoo2.txt

Grab both spoo1.txt and spoo2.txt and post them - unless, of course, he has it working now. If all that matches and ping works then make the ports agree. If they agree and no comms then play with the PC firewall.

Hello Patrick,

you can use Linrad with your Airspy and record unlimited
file sizes. (Your hard disk would be the limit.)

You can locate regions of interest and write small files
that can be converted to standard .wav files if you want
to process on another SDR software.

Linrad uses a 64 bit file pointer while standard for .wav
files is a 32 bit pointer.

Hi there,

A single recorded file (full 768 kHz BW) seems to be limited to 2 Go ; this
means the recording won't last more than about 12 minutes.

Is it possible to record a single file during 30 minutes or 1h or even more
? (still at 768 kHz BW of course).

Thanks

Re: USB cable quality and QRM in a spyserver setup with an Airspy Hf+ and Raspberry PI3. 6 microUSB cable test. #airspyhfplus #bestpractice #raspberrypi

zennix2014@...
 

Can you guys elaborate on the power supply wiring, and also the cable changes? 

I'm heading down the same path (airspy HF+, and raspberrypi), and have had noise issues in the past with other SDRs picking up noise, so more details on connection, power supply make/model, schematics / wiring diagrams, etc., would be very helpful.

I'm unclear about the "self-building" cable part - if you split the USB cable apart or what, so any details help.

I would love to see the Astrospy program have a feature to periodically log data to a file with a a timestamp.  It would be such an obvious feature to add.
