Non-kiwi apps was already set to 8. But I had set the option "Number of channels not requiring a password even if password set" to 2, assuming the number would only include remote connections. I removed the password protection and now ever…
-
@rz3dvp Ah, thanks, I missed that option. I changed it to allow multiple connections from the same IP. It is still yellow on the map. And when I try TDOA it still says "all channels in use" even though both channels are free.
-
Correct, the kiwisdr can't see the source IP address through the SSH tunnel. Interestingly though, the geo ip lookup seems to be working. https://forum.kiwisdr.com/uploads/518/J5KWLHN3S2Q4.png
-
The pin for my kiwi is always yellow, any info why that could be? In the receiver list, it always shows 2/2 available, even if they are occupied. When i select it for TDOA, I get the message "all channels in use" I use ssh tunneling to a …

When I change the tab in chrome for a few minutes, and return to the admin-tab, I get this message that the connection was closed. Maybe that's what PSO meant with "go elsewhere"

Disabling the hardware acceleration fixed it, thanks!

There's this module which switches on the power with a configurable delay: https://forum.kiwisdr.com/index.php?p=/discussion/comment/8733

@jks After upgrading from v1.518 to v1.523 the webinterface shows "Antenna: Mini-Whip", although i don't see that entry in the admin panel. kiwirecorder also gets the location wrong: lat,lon=[ +0.00, +0.00], Grid: RF82ci, Antenna: Mini-W…

The minicircuit isolation transformers are also available in a metal can with BNC connectors, sometimes there are cheap used ones available on ebay. FTB-1-1 with the T1-1 transformer (0.2-500 MHz at the -3 dB insertion loss points) I use FTB-1-6 wit…

@jks Thank you for providing the OS update. I spent the rainy afternoon with upgrading my kiwis, which went without surprises. My WiFi dongles seem to be supported now without having to install additional software, which is great. After the first re…

Hi, Kp6 is moderate, that is no big deal. Even during Kp9 storms I left everything on. It's more of a problem for long high voltage transmission lines, rather than the 110/230V grid.
-
Cool! Must be my best DX so far. But you were on the night side during the flare, right? I think the x-rays caused a significant absorption of the solar radio burst in the shortwave spectum on the dayside.
-
It seems that the waterfall amplitude (on the kiwi webinterface) is now slightly higher on the high frequencies, and lower on the low frequencies, just like in vk3qi's diagram. Spectrum with antenna disconnected: http://forum.kiwisdr.com/uploads/497…

@Powernumpty Ah, thanks for the hint. That could have been responsible for my observation. It was set to -15 dBm and the signal was exceeding that value.
-
I made an observation (earlier than 1.440), I don't know if it is related to this problem. In the presence of a strong signal (can be out of the receiving frequency), the audio volume occasionally drops to zero, and the s-meter shows -127 dBm, but t…
-
Perhaps you can build an LC-oscillator using a varicap, so its frequency becomes voltage dependent. Then you could monitor its frequency on the kiwi receiver, for example using the 27 MHz ISM band.
-
@Powernumpty Interesting finding. Maybe OFCOM would care to issue a sales prohibition? Ours has done so in similar cases.
-
(Quote) The mountains do that for me ;) Good for GPS(?), but bad for DX. (Image) However, I own a GPSDO, (Navstar only, no Galileo) which never archives specified accuracy. Maybe due to lack of visible satellites, or reflections, I don't know.

There was recently a discussion about GRI 99600 (Wildwood): https://www.mail-archive.com/time-nuts@lists.febo.com/msg07726.html

Another case of missing default gateway?
-
I think since he is using static IP adress configuration, /etc/resolv.conf will be permanent. So that should work.
-
The default gateway is still missing. If the configuration is done using /etc/network/interfaces, then you can add "gateway 192.168.1.1" (assuming that is the ip-address of your router) to the wlan0 section. Or for a temporary solution you…
-
The default gateway of your first kiwi is pointing to the disconnected eth0. The second kiwi doesn't have a default gateway at all. So the systems don't know how to reach the internet. There seems to be something going wrong when setting up the ip …
-
@W9SPY You could try using another power supply at the router (maybe the one from the old router). Just make sure it has the same voltage and polarity and an appropriate amperage rating. Using a _non_ shielded ethernet cable may also help. (The B…
-
@f6bir The default gateway could be missing or wrong defined. Can you show the output of "ifconfig" and "route"?
-
@fabrys It looks now much better than the last time I've visited your kiwisdr. I don't think the distant transmitters have anything to do with your noise situation. I still think that it is coupled from a power line near the antenna. Do you have an…
-
Hi Fabrys, I think I see emissions of at least two switching mode power supplies in the spectrum, plus a bit of PLC noise. Can you elaborate the position of the antenna? It should be placed as far as possible from any power lines and electric devic…
-
@fbx That could have to to with the fact that the human brain is very good at correlating brightness to power, but not very good at correlating colors with power. I've read a study about this some years ago but can't find it at the moment. But her…

Yes we have Sporadic-E since two days almost non-stop, 10m was/is open all over Europe! Even at this time (local midnight) i still receive S9+ signals from UK on 10m.

By the way, most transceivers have a "Key" output which goes low/high when transmitting. It can be used to switch off the loop amplifier or LNAs via a relay during the transmission, to prevent damage from high RF levels.
