krakensdr_doa's Issues

DOA Image v1.43 install or path error?

DOA won't start at bootup per photo. Possible path error (or operator error, total linux idiot 😃)?

Connection Status: Disconnected

Hi,

We installed the kraken software via the script

wget https://raw.githubusercontent.com/krakenrf/krakensdr_docs/main/install_scripts/krakensdr_x86_install_doa_pr.sh
sudo chmod +x krakensdr_x86_install_doa_pr.sh
./krakensdr_x86_install_doa_pr.sh

first time we ran the software the kraken connected and the connection status was green.

After trying the second time and following that the Connection Status shows Disconnected on the Web UI.

We tried restarting the system and retry but that did not help.

lsusb shows the devices and running kraken_test seems to recognize the device.

v1.322 Image, Antenna port mapping error? (low impact?)

A possible mis-mapping of antenna ports between the CONFIG and SPECTRUM tabs may exist. To observe it

1. Set CONFIG tab to receive a known active signal and VFO Spectrum Calc to All Ch (TEST ONLY)
2. Connect an antenna to CH0 port ONLY (other ports not connected)
3. Observe SPECTRUM tab, active signal is shown correctly on CH0 (blue) trace only (OK)
4. On CONFIG tab change VFO Spectrum Calc to Single Ch
5. Observe SPECTRUM tab, CH0 (blue) trace shows no active signal (incorrect?)
6. Move antenna from CH0 to CH1. Observe SPECTRUM tab, active signal is shown as CH0 (blue) trace (incorrect?)
7. On CONFIG tab, change VFO Spectrum Calc to All Ch (TEST ONLY)
8. Observe SPECTRUM tab, active signal is shown as CH1 (orange) trace (correct?)

This issue is not likely to be seen if all antenna ports have antennas connected. Please advise if my interpretation is incorrect. Thanks.

Glitch in DoA graph when `Squelch` is active

When DoA estimation is skipped due to the Squelch threshold, the DoA graph in web interface gets a few bogus data points around 0 deg with 0 dB amplitude, as shown in the screenshot. Also the DoA angle is reset to 0 instead of holding the last known value.

Error 404 when accessing PHP Data Out Server Running at 0.0.0.0:8081

Title describes the issue. Whenever I am getting solid 404 whenever I'm trying to run the DOA on my Ubuntu (used the official install script). The same happens on Raspberry Pi with official image. 0.0.0.0:8080 on the local machine or [raspberry_pi_ip]:8080 is resolving fine

V1.322 image, Krakensdr Map function stopped working? (2 receivers)

I have 2 Krakensdr, each on it's own Rpi4. Both work fine with the Android app. Both have briefly worked on the Krakensdr Map site (but usually one or the other, not both) in the last few days. To try to debug the intermittent behavior today I reflashed a fresh V1.322 image, edited wpa_supplicant.conf for my wifi hotspot and confirmed good operation with the Android app when configured for DoA Data Format= Kranken app or = Kraken Remote Pro (with api keys). When configured for Remote Pro and logged into the Map site, Start Remote data does not see either receiver. Screen shots of my Configs are attached. Any advice is appreciated.

Elevation Estimation for RDF

Wondering if it would be possible to add elevation estimation to the UCA RDF using a technique similar to what is described here:

http://www.paluidsprekers.nl/pa8w/elevation.html

Perhaps looking at the max delta time at which the signal arrives at each of the antennas?

EEPROM script minor suggestions

Example output from running the eeprom flashing util:

In the first line, conectent is misspelled, not sure what it's suppose to be?

Additionally, the script as it calls out channels numbers are indexed as 0. (0-3)

Please turn off all channels excepting channel number:0

The dip switches are labeled 1-4, and the serial numbers are 1000-1003.

Might be better to have the script call out the DIP switch labels (1-4) that should be on, and/or a serial number scheme of 1001-1004 ?

DOA Issue: Kraken stops functioning set at 1.68 ghz (NOAA wx balloons)

V1.4 image, DOA is working fine at 853.85mhz (antenna array supports 700-1700 mhz). If I change frequency to 1.680 ghz, the config shows errors (see photo) and won't recover without Software Restart.

Error switching from DoA Graph Type from Polar to Compass

Ran into an issue using the latest rbpi image, after running for a bit, switched between the DoA Graph Types, and after switching from Polar to Compass, the terminal threw this error, and the UI become unresponsive.

Feature Request: Peak Hold in Spectrum Display

As the title states, this is a feature request. It would be useful to have a peak hold function in the spectrum display.

Add clean shutdown button

While unlikely, pulling power to the Pi 4 could end up corrupting the SD card.

We should add a shutdown and restart button to the web GUI.

Map server feature request: Multiple receivers, Indicate which bearing is which receiver

When using multiple receivers, it's not clear which map bearing is for which receiver. Especially important for mobile Dfing. Suggest adding a bearing source label or some method to correlate receivers with map bearings display.

Automatic calibration of Kraken software for old Kerberos SDR

Hello,
I looked for information on the automatic calibration carried out by RF coaxial switches and I fell back on the ckoval7 's fork which worked well with my old Kerberos version.
I don't know if this has been transposed for the Kraken software when using DQA kerberos example files?
I did not find any traces on the different supports and my GPIOs on pins 18 / 16 are not controlled during calibration.
Is there an implementation planned or did I miss something?

Sebastien

ZeroDivisionError: division by zero

Unsupported Compression Method: 14

About to do a road trip. Had some ULA signals lined up. Noticed the update. Downloaded. BalenaEtcher said the v1.4 zip file was unsupported. Realizing my age and level of stupidity I thought maybe I touched something wrong. Tried directly from the link to the file on github. No dice. BalenaEtcher cried again. I can't update. Using a Win10 machine with MS Edge browser....Also, why is it the other version zip files have disappeared? CYA decisions or we're not allowed to blend code between versions?

Use JSON for config files

There seems to be a mix of usage of JSON and INI file formats for config files in the projects.

https://github.com/krakenrf/krakensdr_doa/blob/clientside_graphs/settings.json

https://github.com/krakenrf/heimdall_daq_fw/blob/development/config_files/cw_15kHz/daq_chain_config.ini

Ideally should just use a single format and stick with it. JSON is superior IMO to INI file formats.

DOA feature request: Display squelch setting on spectrum graph

It would help ensure the squelch level was set correctly if a line showing the level was drawn across the spectrum graph. This is especially important for tracking intermittent signals so you're not processing noise or missing transmissions.

Can't get a webpage, Ubuntu 20 on ODROID N2+

Hey there, I don't think this specific error has been addressed yet. I am expecting the arrival of my kraken soon so I was setting up the software in advance. This is to say I do not have the krakensdr attached yet. Setup seemingly went fine up until actually starting the kraken_doa_start.sh file. Here's the output, which looks fine to me:

v1.5 spectrum and doa graph freezing/not drawing after a while

So with 1.5 the spectrum view and doa view as well become frozen after a while, this have happended to me on 3 separate runs around the block with the kraken. This is only happening with 1.5, not with 1.43.

Edit:
So luckily I was recording at the time it happened, so I can show how it looks like.

Here is a video of the problem.

This is how the compass looks like when this is happening:

This is how the spectrum/waterfall looks like when this is happening:

And here the first few lines of the log (configured on the web interface, not in the mobile app) of when this happened:

Here is the same log visualized with the map:

And here is the log it self:
log.csv

I took a look at the log, and what is obviously not good is that the GPS coordinates are missing. Now I don't see what would cause this, or why would this have any effect on the spectrum or DOA graph, but this is the only deviation in the log I see.

I am also running the Wigle WiFI and BT gathering app (it relies on GPS as well) while using Kraken, but 2 apps using GPS was never an issue before, and still not causing issues with 1.4. So I dont think it has anything to do with it.

Update default locale / keyboard on demo image

Debatable if this is worth changing, but I'd suggest switching from the default GB to en_us_UTF-8 and to standard US keyboard layout in the default image.

DOA feature request: Display software version

Handling multiple Rpi SD cards makes it easy to mix them up. It would be nice if the software/image version could be displayed on the Config screen.

Customer Feature Request: P25 monitoring

An application that uses one (or more) sdr's to monitor a P25 (or others
depending) while the rest scan through the input frequencies (i.e. 700Mhz + 30,
or 800Mhz -45) to find local activity, and show what system(s), group id, and
radio id is on that frequency. With option to log naturally. Another idea: Is
it possible to 'bridge' two Kraken together to act as one 10 channel system?
The other software (GQRX, etc.) has a slow scan speed (approx. 8
freq's/second), and using several sdr's to 'leap frog' through a frequency list
would speed things up. But you would know about that more than I would.
Anyway, thank you very much. Looking forward to get out 'in the field'.

Email submission: Direction dependent deviation tuning

Leaving this email suggestion here for looking at when time allows.

Submitted by a user whose seeing somewhat predictable multipath skew on a fixed indoor antenna array. Not sure yet how feasible this suggestion is as the deviation would only be valid for that specific transmitter and that specific multipath deviation from that transmitters direction.

A better solution might be to look into a calibration algorithm that can take into account prior known transmitter/frequency bearing data to try to detect and null multipath.

First, I like to do a lot of DF from my house - unfortunately with the antenna array mounted indoors at the highest point below the ceiling. Likely due to multi path, this gives me a few challenges. While I am getting VERY consistent bearings for known transmitters, these are often off by 9-12 degrees, occasionally a bit more. 

There seem to be a pattern to the deviation: Transmitters located approximately between 315 and 45 degrees compass need a  positive correction, remaining transmitters need a negative. This impression is from sampling transmitters mainly W or between 34 and 120 degrees compass from my location.

As there may be a predictable pattern of deviation - at least in the 430-380 MHz band I monitor, I have a suggestion:

Allow direction dependent deviation tuning. Something like:

Estimated DOA	Correction
235-45			+6
45 - 90			0
90	180			-8
etc.

Ideally with user defined number of entries. I currently do not know if this deviation is frequency dependent.

Other suggestion from the user. Will be split into their own issues if we decide to work on them.

Easy switch between fixed and mobile use with a button on the map page

Fixed button:
- Prompt for Lat/Long/antenna orientation - remember last position
- Even Better, allow quick selection of saved locations (my favourite 5 hilltops in the area)
- Disable DOA when moving only
Mobile Button
- Orientation = Compass
- DOA when moving only

Remote control via API. (Could be possible ?). I like to develop a plug-in for SDRUno to set frequency, gain once an interesting transmission is detected.

Button ‘Send to RDF Mapper’ I only want estimated good DOA measures uploaded

checking version number of software

When not installing the software on a Pi, how is the version number verified?

Android App won't connect to "KrakenSDR Server Settings"

Where I'm at:
The DOA server starts, and I am able to access the settings website via the :8080 port on the host computer, which is an older HP laptop. It appears that I can make settings changes as well.

I am able to also access all 5 of the SDRs on the host computer using GQRX (while not running DOA server)

I am able to connect the DOA server host computer to the WIFI hotspot on my phone, and have a good connection (can websurf as expected).

I can open the KrakenSDR App on the hotspot phone, and for the most part, it seems to work. However, even after setting the server computer IP in the settings menu, I cannot access the KrakenSDR Server Settings. If I go to that portion of the App, I just get a white screen with the "return" arrow in the upper left.

VFO-0 spectrum window graphic is wrong when used with KerberosSDR

Note to fix this in next version.

The recent clinet_side_graphs questions

From what I see in client_side_graphs the major update is in the squelch and graphing (addition of waterfall) right?

Latest image doesn't have PIGPIO support included

Testing out the latest image, it looks like when the heimdall daq fw was built, the line #PIGPIO=-lpigpio -DUSEPIGPIO
wasn't uncommented.

DOA Issue: GPS location "Disabled" at startup (Image v1.4)

I have the Station Information, Location Source: GPS in my saved config file. At bootup, the system starts operating OK but with the GPS = Disabled status. I have edited /etc/default/gpsd as

Default settings for gpsd.

START_DAEMON="true"
GPSD_OPTIONS="-G"
DEVICES="/dev/gps0"
USBAUTO="true"
GPSD_SOCKET="/var/run/gpsd.sock"
and confirmed the gpsd Daemon is running at startup.
However, DOA appears to be using the last (possibly invalid) GPS location for DOA reports, both locally and on the Kraken RF map site.
Deseleting and reselecting GPS as the Location Source appears to allow the GPS to Connect. However, I'm trying to configure a remote DF station that can operate from bootup without user intervention.

Kraken Pro Cloud Mapper : how to add another KrakenSDR ?

Hello all,

I've added the first KrakenSDR on my map.krakenrf.com new account and copied the app key, it's working well.

Now i'm trying to add another one, entering the second Kraken serial, name with space, frequency and decay time, clicking on "create station", I received an error . " error : you forgot to fill all fields or entered a wrong serial"

What's wrong ?

Regards and happy doa ;) !

Radar Detector?

I've been thinking about it lately, and it seems to me that possibly with some kind of LNB or BDC, it would be possible to use SDR to detect, for example, X/K/Ka-Band radar signals often used for determining vehicle speed.

Current high-end commercial radar detectors cost upwards of $600-800 and often come with two antennas, which is better than only one, but it would seem the almost ideal candidate for this application would be with something like the KrakenSDR.

The main issue would seem to be the fact that these signals are pretty far outside of the typical range of nearly all SDRs and therefore necessitate at the very least some kind of downconverter, but I've been unable to find much (any) information anywhere online about this being performed in practice.

Is coherency being maintained whilst utilizing a downconverter even something that is theoretically possible? I know that the results using similar yet different individual LNA's looked quite positive at least, so it's not really so much of an issue but just a question as to the feasibility of doing something like this in general, so this can be closed if it's the wrong place for something like this...

Add option for only frequency of interest

The current behavior appears to be that the strongest signal within a pass band is selected for DOA.

If there is only a single frequency of interest being DF'ed, this can lead to that frequency being ignored and/or a bunch of additional unwanted data.

It's mentioned here [0] [1] that multiple channels with independent squelches, which is a nice feature. It'd be desirable to have a option/mode to ignore everything other than the frequency of interest though.

[0] - https://github.com/krakenrf/krakensdr_doa/tree/clientside_graphs#upcoming-features-and-known-bugs
[1] -

[FEATURE] Currently squelch works by selecting the strongest signal that is active and above the set threshold within the active bandwidth. The next steps will be to allow users to create multiple channels within the active bandwidth, each with their own squelch. This will allow users to track multiple signals at once, and ignore unwated signals within the bandwidth at the same time.

Confirmation of dash version...

I'm attempting to set up krakensdr_doa on an intel NUC, due to having experienced big RFI issues with RPi4's.

After following the instructions here verbatim, I end up at the point where i startup the software, but the main webserver on port 8080 doesn't start, with the following error:

I can confirm that the dash version is the one specified in the installation instructions (1.20.0):

>>> import dash
>>> dash.__version__
'1.20.0'

Is this actually the version that is required, or are these instructions out of date?

Issues when disabling WIFI

There where reports that the DOA Software stops sending Data to the Remote Server (map.krakenrf.com) if wifi is disabled despite it being connected to the Internet via Ethernet.

The Kraken Software tries to connect as a client, if this doesen't work it will create an AP.
My guess is that this fails when wifi is disabled and causes an issue in the Software Stack startup.

One User wrote:

It's a Stationary station. Everything works on Raspberry PI4 V1.43, but I

@krakenrf Carl please have a look if this is the case

Pi4 Shutdown feature?

Is there any way to safely shut down the Raspberry Pi? With this operating in a headless mode, the only way I have been able to power it off was to just remove power from the Pi. Certainly, this is not good for the SD card or file system. Can a power down option be added where we can press a button in the app to power down the pi, or allow us to use a switch on pins 5&6 to power it down safely?

Thanks,

balenaEtcher-1.5.115 fail to flash microSD

In the printed KrakenSDR Users Manual on page 11 it is recommended to use balenaEtcher to flash an KrakenSDR DF image. It failed for me. BalenaEtcher (used balenaEtcher-1.5.115.dmg from https://www.balena.io/etcher/ ) could not unmount the SD-card Sandisk Edge 128GB.

My OS is an updated MacOS 10.15.7. I used an elder Trancend SD/MMC adapter, that support up to SDHC - the SD-card is a microSDXC.

A friend recommended to use Raspberry Pi Imager (used imager_1.7.2.dmg found here https://www.raspberrypi.com/software/ ). Raspberry Pi Imager worked (no cog settings was used).

Please consider updating or supplementing your (printed) KrakenSDR Users Manual with the alternative Raspberry Pi Imager.

Feature request: Continue DOA estimates when mobile station stops moving

I understand GPS headings go invalid near zero speed. But hearing a very intermittent signal go active when you're stopped at a traffic light or briefly parked and not getting a bearing is frustrating 😭. It seems if you had an auto Stationary on/off mode that would use the last valid gps info when stopped, then go back to live gps when moving again, it would help greatly with intermittent signals. Preferably in the DOA code but minimally in the android app.

Image 1.4 DOA issue: Spectrum Autoscale stuck on?

When attempting to use the [zoom], [+] or [-] control keys on the DOA Spectum screen, the screen changes briefly when the control is selected, but then immediately reverts to full (auto?) scale. Pressing the [autoscale] control (toggle?) does not change the symptoms. Observed in firefox on a windows PC and Samsung Tab A8 android tablet.
