All good! I appreciate the mobile phone interface improvement! Ron KA7U

This might be a near sighted idea, but could KiwiSDR's be connected as Beowulf clusters? Or could one KiwiSDR benefit from the additional computing power of additional Beaglebones or Raspberry Pi's added in a cluster? Ron KA7U

for pid in $(ps -ef | awk '/python/ {print $2}'); do kill -9 $pid; done This should kill all instances of python that you have running. Ron KA7U

@Jon5 If you find you are really getting into Bash scripts, and they are quite useful, I'd suggest you add training on the terminal "Screen". It has multiple instance features, allows you to exit and return to the running screen, and so f…

@Jon5 I've been out fishing for the last couple of weeks. Camping and fishing, good thing to do. Back home now. So you have the cron job working! Wonderful. A Bash script looks a little different. So open a file in your editor, and type the follo…

There is a discussion on running python scripts concurrently here: https://stackoverflow.com/questions/28549641/run-multiple-python-scripts-concurrently Ron KA7U

@Jon5 I wish I knew how to work with that script; can you give me an example, perhaps if I wanted to record a specific site, say yours, at 10 AM today and then stop at 1 PM? The problem with scripts for me is that it takes me forever to get the pun…

@Jon5 , you can setup a cron job in Ubuntu to start and stop your scripts: ron@linux-4cdz:~> crontab -e # .---------------- minute (0 - 59) # | .------------- hour (0 - 23) # | | .---------- day of month (1 - 31) # | | | .------- month (1 …

I asked the question. (Image)

@Gary , I think you are right. This morning there is no interference on 3780kHz or elsewhere on the 75/80 meter phone bands. I wonder if it will come back. (Image) Ron KA7U
-
@Gary , I placed a MW filter inline and it dropped 1260kHz from -28dBm to a -56dBm but the signal at 3780kHz remained at a -90dBm with and without the filter. So it is apparently a legitimate 3rd harmonic. I do have a notch filter constantly inline…

So DX Engineering is selling these in pairs, presumably to be installed on both ends of an Ethernet cable to prevent the cable from radiating and to help isolate the attached equipment from the common mode currents on the cable? In the case of the K…

Thanks guys for the information. 120 lines versus 60 lines, I get it. I will need to try kiwifax.py . Ron KA7U

Glen, I've read through your PDF and admire what you are doing with this switch board. Awesome! Ron KA7U

I suggest you clear your browser cache and check again. Ron KA7U

My active loops have this in varying degrees over a period of hours and days. It has gotten worse this winter. My dipole does not seem to have it to this amplitude, but it is there in the noise. Active loops https://ka7u.no-ip.org:8074 & 8075 , …

append this to the URL of the kiwi you are working with. ?f=22500.00amz1 Ron KA7U

I think this discussion is relevant to your error message: https://stackoverflow.com/questions/46448682/cmake-error-the-source-does-not-appear-to-contain-cmakelists-txt?noredirect=1&lq=1 Ron KA7U

Oh, oh, guess I wasn't paying attention! The Dream receiver reports the station as WINB. http://www.winb.com/ Ron KA7U

Alan, If you haven't already done this, try opening settings/history/history/clear browsing data/cached images and files That might solve it. Ron KA7U

Most of my motivation to limit user time on the KiwiSDR's came from the users themselves. Hams mostly, that "need" to monitor the nets that local noise prevents them from hearing well. So I made timeouts and passed out passwords, and tried…

I use DD-WRT routers and if I want to block an Internet user I'd setup a rule in IP tables like this: First I'd get the user IP address from the user.log on the KiwiSDR: ssh to the KiwiSDR then run this command: root@kiwisdr:~# cat /var/log/user.lo…

Would this extension be an accommodation for a blind person?

Verizon is my cell provider and version 8.0.0 works fine on this phone. Ron KA7U
-
When I check for an update, the phone service provider shows 8.0.0 as the current version for the system. So the updates are pushed and I don't know how to update out of the system provider's schedule. What is more, I do not know the consequences of…

Works fine here on my Moto Z Force Droid, Android ver. 8.0.0 Ron KA7U

My friend K7UQ has one of these loops. It does work better than most built in antennas, but it isn't really super duper. An active loop inside is usually very noisy, same with a mini-whip. Taped to the glass is probably as good as it gets. Better to…

I have a SWL friend that is apartment locked with the antennas inside the apartment. I will be interested in your final solution for the indoor antenna. My friend is currently using a 1 meter coax loop inside his apartment and while he gets some rec…

Martin, I do find http://ve3sun.com/KiwiSDR/ to be a very good site and I think the most complete. The http://rx.linkfanel.net/ site is the most intuitive to use, but the http://rx.linkfanel.net/snr.html site ratings are a bit off, or at least it …

@linkfanel Happy New Year! It has been awhile since I've heard any updates to this thread. I check rx.linkfanel.net often and it is easy to use. I do notice that the scoring system does not necessarily reflect the expected quality of the receiver…
