V1.382, current. I manually kicked all of the users from the Kiwi, the RPI4 added its listeners back as expected, and I logged in again from the same browser (refreshed the same page that was previously showing that message), and I had no issue runn…

Yes, I had noted this. My current workaround is to tap shift+"s" once to set auto scale, then tap shift+"w" between 5 and 10 times quickly until satisfied with the appearance of the waterfall. I'm usually tending to go 10 steps s…

Very nice. A wonderfully quiet location in comparison to my own sites, though it would appear someone in your vicinity has powerline ethernet.

VNA version 2 is also due out relatively soon, with larger frequency range and a few other improvements. Anyone looking at NanoVNA purchase, note that there are a number of Chinese clones, some of which do not have the RF shields in place and have …

@rrobinet Nice work. I'm also getting one of the same errors as Ulli above: Traceback (most recent call last): File "/tmp/wsprdaemon/noise_plot.py", line 72, in noise_vals=noise_vals.reshape(n_recs,14) # reshape to 2D array with…

I've come across some BBAI wifi instability over the past 36 hours. My setup has the BBAI using connman to connect to a 5GHz router and statically assign an IPv4 IP address, and I've also got the BBAI connected via USB-C to an Intel NUC. I've had t…

Hi John, thanks for looking in on that. Much appreciated! Yes, it's an active antenna - specifically an active-antenna.eu AAA-1c. I did have some manipulation of the radio-end of the antenna system when I was doing the install/swap of the BBAI, and…
-
^ that's a nice clean cooling setup. My BBAI arrived, I was able to do the OS updates and kiwi build in the office before doing the swap when I got home. For cooling, I have two 40x40x20mm 5v Delta fans, each pushing 5.5 CFM. I had them ducting thr…

I decided to bite the bullet, and I've finally ordered myself a Beaglebone AI, due to arrive Monday or Tuesday next week. I've been wishing I had more audio channels, and more processing power. I run 6 or 7 WSPR listeners from an RPi4 on both of m…
-
It's quite a test of the low frequency capabilities of one's receiving setup. Neither of my Kiwis can see the Alpha transmissions, even when integrating. I've a little bit of RFI down low on the antenna that I would have expected to hear this signa…
-
Finally decided to take a good look at the DRM plugin, as I've got temporary troubles with the Pi4 that performs my WSPR decodes, so my Kiwi now has a little while where it's not providing 6 or 7 WSPR streams. I've got very clean decodes at 22.00 U…
-
I may have to upgrade the kernel on my Kiwis in order to better utilise the wireless USB devices I have. The device I am using on one of the Kiwis is seeing only the 2.4Ghz networks, though it is supposed to be dual band 2.4/5 and I am suspecting a …

Using ethernet and not wifi? You've set the correct parameters in /etc/network/interfaces, and commented out the eth0 dhcp definition? Example like this. (/etc/network/interfaces) auto eth0 # iface eth0 inet dhcp iface eth0 inet static address 192.…
-
:) Yes, I know that one pi4 can happily take the output of of two BBG Kiwis, but my Kiwis are one in Limerick and one in Zurich, so not to easy to do one for both.
-
Might want to update the title of this thread? (Both kiwis are now providing audio streams to a pair of Pi4s, both now happily appearing to decode at 2.6a version.)
-
Mental note to self, check the case of things typed in as identifiers.. in the wsprdaemon.conf I had followed the apparent convention of AA00aa with the second pair of letters being lower case, and I was looking for AA00AA on the website instead. L…
-
I like this extension. I had been attempting to manually decode the amplitude encoding from both, the MSF60, and the DCF77 signals for a while now out of sheer curiosity. The timecode extension works very well for me on the MSF60 signal on my own …
-
That addition is helpful, when I'm searching for NDBs the averaging makes the morse components stand out a little better against the background.
-
That's interesting for sure. I'm in the top 40 listeners, even with a poor quality antenna. (swlio52rp)
-
Understood - thanks for the explanation. More tweaking for me to do then! -Cathal

One thing I've noticed with the waterfall, is just how much improved the view looks when changing the zoom level outwards. For example, if I'm at z9 looking at an AM signal, and I have a full waterfall showing in the window, and I go to z8 the visib…
-
It is a pity, as I found it very useful. I wonder if it would be possible to clone the behaviour of the site, as I have access to servers that may be able to provide this type of service, from a university network.
-
I've an MLA-30 set up as a vertical dipole with 2m of wire on each side. I had to use a different bias-tee as the provided one killed all reception under about 500 kHz. Compared to my 20m randomwire, my noisefloor is up about 20 dB but SNR generally…
-
Cool. I'll tinker a bit as I get time, but will be waiting to see your success :) Thanks for the response!

How was the kernel module for the 8192EU chip compiled? I just received a D-Link with the 8192eu chipset in it (2001:3319 "Wireless N Nano Adapter"), and I'm having a bit of trouble locating code that could be compiled for a kernel module…
-
I added a 10m rg8 extension (with f-connectors and adapters to SMA) to the GPS coax cable, that brought the antenna from the gap between the houses to the top of the garden shed with a much better view of the sky.. I've now got a solid and consist…
-
Cheers for the reminder about that doc. It makes for interesting reading. I had last looked at that, when setting up my GPS-led network time server and researching which cheap serial-accessible GPS kit was going to be most fun to play with. My tim…

Working beautifully here, on a Pi4b running Buster, SWLIO52RP as the callsign as I've not yet earned my license.. 5 threads running from my Kiwi, not much load to be seen on the Pi. The noise graph is a great addition compared to the kiwiwspr daemon…

Confirming the access attempts from 47.88.219.24 on my own Kiwi, which has been online ~18 days. I've ~690 attempts logged starting Aug 5th, last one on Aug 8th. I do like iptables for these kinds of things, though dropping address ranges is a game…
