Beautiful captures of Type-III emissions!
-
The kiwi has a low pass filter ahead of the attenuator. That should give some extra protection for frequencies above 30 MHz. Maybe John has measurements or simulations, but a quick simulation that I ran gave -24 dB on 50 MHz and -92 dB on 144 MHz.

@ve6jy Looks like you were typing journalct1 instead of journalctl
-
@DenBoz You were typing kiwi.jason but the file name is kiwi.json, are you sure you were editing the file correctly?
-
Maybe it would be a good idea to limit the log file size (/etc/systemd/journald.conf)
-
I should have known that. It's really much faster. Thank you.
-
As far as I could find out, and as far as I understand, the IP address alone does not qualify as personal data, since it can change over time. (And it is technically required to be processed, for example to prevent abuse) If a user identifies himsel…
-
To store the name/call of a visitor with their IP address, the consent of the user is required to comply with GPDR/DSGVO. It would be good if this could be added.
-
That's a lot of interesting products. Thanks, Martin.

@IK8SUT The image doesn't get updated with new kiwi versions, only with OS updates. The last (debian 10) image had a 2 year old kiwi version when it got replaced with debian 11.
-
I think 8.219.247.109 (alibaba cloud) is doing the same as the russian datacenter guys. I've seen that for quite some time but didn't bother, as they did it not as extensive as the russian guys, only maybe once or twice a day. It looks like they are…

@studentkra Thanks.
-
It's hard to get better coupling than 20 dB with reasonably spaced antennas. But what I do with Kiwi1's: Transmit first with very low power and check the signal level on the kiwi. And then calculate how much it can take.
-
Special care should probably be taken at low frequencies. From the PE4312 datasheet: https://forum.kiwisdr.com/uploads/979/PKDKU8V4LX4Z.png
-
The antenna is active. There are passive and active GPS splitters, mine work well with an active one. With a passive splitter, the signal might be too low. And you potentially need to take care to not backfeed the 5V bias to the other kiwi, although…
-
@jks Is it safe to keep the kiwis on the old debian 11 image if my KIWISDR10 kiwis didn't had problems? (So the part number will not be overwritten with blank spaces in the future)
-
Do you turn on the power supply while the kiwi is plugged in? Some power supplies ramp up too slow for the kiwi and it won't start...
-
@jnijkamp Do you have connected the power supply to the kiwi or the beagle board? IIRC the beagle board can't deliver enough current for the kiwi if it's powered from the usb port.
-
Impressive, that works surprisingly well. I'm curious how you did that.
-
Well that's odd. Does it get an ip address with "dhclient eth0" ?
-
fe80:: is a link local adress, it assigns that itself. @WA2TP Does that ethernet cable/connector work on other clients? can you show the output of "ethtool eth0"
-
--- If there is no power down within two minutes the fix didn't work. Try the procedure again. It would be also interesting to know if it is getting an IP address from the router while it is blinking twice. If not, it is probably something wrong wit…
-
You can see older logs if you log in with ssh and type "journalctl |tail -n 1000" (1000 is the last number of lines that you want to see, it will take a few seconds)
-
I tried the script on a spare BBG and it runs fine here... @bob53bob It is http://kiwisdr.com/files/KiwiSDR_BBG_BBB_EEPROM_fixer.img.xz if you can write it on a PC. But I wouldn't trust that BBG in this case...
-
What type of power supply do you use, can you measure the voltages on the kiwi board, particularly 5V/5VE? http://kiwisdr.com/ks/troubleshooting.pdf In another thread you mentioned that you were using a relay board, does it happen when you switch it?
-
Additionally to what John said: Perhaps the volume slider in the "audio" tab is at minimum?
-
I wonder why I don't have these problems, but my v1 kiwis have uboot_detected_capes=KIWISDR10 Also I'm using wifi dongles, which perhaps aren't affected. But I tried it with ethernet too which works as well.
-
Yes, it's already powered up. From what you wrote, it sounds like the image was loaded successfully onto the Beaglebone. Assuming the led flashing back and forth, and it turned off afterwards. But John seems to have found a problem with the image, …
-
Given the fact that you're the second one with a similar problem.. I wonder if you can change the IP address if you keep the default port.
-
Yes, the part with the image sounds ok. Also the double flashes is normal after successful boot, I think. It should get an IP address from the router via DHCP.
