See wsprdaemon thread(s), it is exactly that, and more. Stu

Zyg, For the interested watchers.. What power supply are you actually using (voltage and current)? Does it have a decent 5.5mm/2.1mm plug on it? Only reason I ask is that many of us have tried unsuitable power supplies that allow the voltage to dip…

Are you using any kind of VPN? I.E. does the browser get to the internet through the same gateway as the Kiwi?

Shout out for macvendors.com. Also if it has the feature I'd ping from the router direct over different cables and alternative network ports, that thermostat ping time over wireless (assumed) is very variable so take all other links out of the equat…

Try the link from http://my.kiwisdr.com/ It's not normally worth trying the WAN address from the LAN side of a router.

Yes has all the signs of a scam. Google All orders are treated with the utmost care to meet the needs. Our customers appreciate the importance of your purchase, and there are loads of other junk sites. Alternate "Please allow an additional 3…

That site reminds me of one I found accidentally. Imagine there was a site called fbuyer.com and then I stumbled on another called kbuyer.com with 1:1 graphics and products. I reported the duplicate to the first site and they were, A. unaware, B. Su…

SSH, port 22 should be open locally on the network using an IP address, normally something like 192.168.x.x. Check that address from http://my.kiwisdr.com. It would be better to get used to SSH from inside the network. Opening it to the internet re…

Thanks Jim, Something about wanting to use "logger" and "watch" stops me sending it the log I can look at (quickly) while at work. I can work with root@kiwi:~# while true; do logger --size 3 -n 1.2.3.4 `ct`; sleep 30; done I …

Thanks that would work. I was sort of looking for a command I could run for a short time to check maximum's over that time when I'm testing things. I should probably look for the temperature commands specific to the AI then try that direct.
-
Is there a simple way to pipe the maximum temperature (in for example 10,20 or 30 second intervals) to the syslog or another log? I've set the AI to 1.5GHz and 14ch internal WSPR, at a glance from "cm" I saw 52000 but it is mostly running …

(Image) (Image) Obviously I omitted the old AMD cooler on the outside and the heatpipe is actually stuck with thermal adhesive now. The case opening is also a slot now. Idles at at about 52C with fan off DRMx2 42-43C with fan (12V fan at about…

Another option. Get a car GPS repeater, put that RX antenna as high and clear as possible. Angle it as Jim suggests but either way get the first RX antenna a clear view into as much "sky" as possible, then put the Kiwi puck facing the rep…
-
I have found GPS quite intolerant of reflections, move the antenna a little? Coax cover (at least the small puck antennas) - one small nick and the "copper" disappears into white dust very efficiently, the only outward sign being a less fl…

That last "6-8 WSPR + 2 normal" strikes me as a good move, I have shut my IA down so I can get back to thinking about heatsink options. New Xmas electrical items at neighbours knocked my (14CH) WSPR results badly so it's good time to work …
-
The only way IMHO is to have a large passive heatsink. The copper laptop cooler I used, if left with the fan off, idles at about 60C on a cool room. I only found this by accidentally knocking the fan supply and spotting the elevated temperature late…

From https://twitter.com/dd5jfk follow the tweet+link mentioning Amazon "list of Raspberry Pi images" I'm trying the latest one (2020-01-04) and it is much better than the github listed version. Obviously I've been spoilt by Kiwi (I keep …
-
In my location, most of the day it needs to be a solid S6-7 due to the QRM (just below that, worse since Xmas). As the signal is digital it's "all or nothing" you won't hear a noisy digital decode, it also doesn't like dropouts so "tw…
-
Was playing with this again. The RTL dongle connector seems to work better than the soapy one. I can't work out how to use the gain values for a RSP1A, they seem to be negative values but still I get intermittent overloading when the gain is dropped…
-
The log would be a good start. There might not be enough space for the download or some corrupted update files but the log should report how far it gets. I'll search for a previous thread, pretty sure reclaiming space or forcing a complete clean do…

Just to put some power consumption detail on this. I purchased a RB750UPr2 hEX Lite router (no fibre) to compare to the switch above. The router on its own seems to take in the region of 1.6W (at 23V) With one normal Kiwi powered through a POE por…
-
I'll get some kit together and do some real world tests, what I think the running power would be, depends on too many variables including the type / make of fibre module. The fibre convertors do get warm so must add some to the power budget, if the …

First I've heard, With things like GDPR and probably some countries not wanting their sheeple to have access to dissenting voices I bet there are "pressures". If Andreas has to focus on other work to put food on the table reducing his expo…
-
I'll have a go later, I have found Mikrotik equipment generally very efficient so would guess at more like 3W max in this switch setup. it obviously will depend on throughput/ enabled ports / type of Fibre module fitted so let me know what level of…

I assumed the same, "inevitable" that there would be RF but saw a few fences for sheep installed that I had not spotted by radio, only by eye. Grass touching low wire was easy enough to track by ear and remove, then the noise blanker caug…
-
https://www.arrl.org/files/file/Technology/tis/info/pdf/9604062.pdf Good place to start. Here I find when the grass grows up to the bottom of the fence that normally will get it going but also wires twisted together or just plain corrosion. I think…

As I said before, the coax forms part of the antenna so separate it into two sections if you can. 1. the part closest to the antenna, that part has the largest affect on signal 2. the part closest to the receiver, that has the most affect on local n…

Sorry for slow reply. My wiki is on sdr.hu under M0AQY but note it is set up more for digital weak signals like WSPR, than voice, there is also terrible noise from one long term source. Check http://graphs.wsprdaemon.org/M0AQY/ if there is 20db extr…
-
1. Yes, Mini whips can pick up a lot of noise on the feed, experiment, satellite coax like WF100 has great shielding at low cost, before I moved to WF100 generally I used coax (RG58) vertically down (7m) from the antenna then CCTV balun and CAT5 bac…

"my other AI" nicely played sir. I think it is admirable that you are still prepared to talk those of us with only one.
