Martin, this is exactly what I was looking for. Thank you for experimenting with the power supply! In most of the ready-made modules, a 100kOhm resistor is installed on the MP1584, which sets the frequency of PWM operation. You can reduce its resist…

After starting a new receiver on short waves, I received interference from a switching power supply. Partially they were reduced by a power filter in front of the 220 volt outlet. I'm thinking of using a 12 volt transformer power supply and a 5 volt…

https://forum.kiwisdr.com/uploads/107/9LA8HY6EHOC6.jpg https://forum.kiwisdr.com/uploads/393/Q1BV99W3V5CR.jpg I have been using a small python script for one year. It analyzes log and writes all connections to a special file. A small adaptation is …

Now I have tried the latest version of Mozilla Firefox on an Android phone. Everything works well. The sound does not stop even when the screen is turned off. Unfortunately, I don't have an iOS device to test this. UPD: No. I was wrong. After a whil…

I don't like it very much either. But that's what mobile browser developers want. Well, I think a solution will be found.
-
There is no solution. This is a problem with all mobile browsers. And not just kiwisdr. There is only one solution, output the audio stream to a separate application. But it's a lot of work!

Geolocation is primarily determined on the client side. If this is not possible, then the ip address of the client is sent to the server and the geolocation is determined on the server side.
-
Thanks, John. Great job! 👍️
-
The entire kiwisdr program code is written so that the frequency scale starts at 0 kHz. This is especially true for the server side. The client part processes the sound and waterfall flow considering only the frequency offset that is specified in th…
-
The thing is that kiwirecorder does not know about your frequency offset. It is for this purpose that the offset frequency was added to the address mykiwi.sdr:8073\status so that none-kiwi applications could determine this frequency. Set the frequen…
-
If these are really bots and not real people, then this will not stop them. They will listen to masked frequencies and occupy free channels.
-
That's right. DX labels are tied not to the frequency but to the beginning of the scale. I agree with you, it's very inconvenient!
-
Oh sure. Javascript is completely executed on the client side and user can do whatever he wants with it. Fixing the software part of the server is very difficult for me! I only offered simple options for KiwiSDR owners. Perhaps @jks will use it to…
-
I changed the javascript a little. Now the https://vpnapi.io/ service is used. This is a free service for determining VPN, proxy, etc. However, registration on https://vpnapi.io/ is required. After registration, you will receive a personal API key, …

There are paid services that can very accurately determine whether an IP address belongs to TOR, Opera VPN and etc. There are free services for determining the privacy of IP addresses, however, as I have noticed, they are often wrong. You can use a …
-
@jks, it would be nice if we can leave comments in the personal blacklist in the web interface about ip address. I update my blacklist very often. And I keep forgetting which addresses I add and for what reason. I think many people agree with me.

SQL and AGC corrupt the beginning of the file record. I tested on different KiwiSDR. A piece is missing from the beginning of the record, while SQL is opening. And not from the very beginning. 0.5 seconds is fine, then a fragment is missing for abou…

G8JNJ, try to set the AGC Decay parameter to the minimum value. https://forum.kiwisdr.com/uploads/536/4XA55RXYBLVJ.jpg

@jks, thanks for the detailed description of GPIO. I have not studied this in detail. Just assumed to use a Beaglebone hardware UART.
-
Beaglebone green is already has a serial port on board. No needed USB-to-serial# adapters.

I am always ready to help!😎

Its very easy to do! Iam using transparent panel for a long time. https://forum.kiwisdr.com/index.php?p=/discussion/comment/13722/#Comment_13722 https://forum.kiwisdr.com/uploads/716/6G0HMOPB6OG7.jpg

I am using a small python script. It runs every hour on schedule( cron @hourly python /home/flydog/logs/User_log.py). Scans the Kiwi log file and writes each user's connection and disconnection data to a separate file. Information about attempts to …

From about 20:00 UTC June 3 to 10:00 UTC June 4, I saw similar problems with any kiwi in my country. The admin page took a long time to load. The waterfall was stopped. Maybe there is some connection? The ISP reported problems on its end.
-
On my receiver, many bots "sit" on frequencies where there can be no signals. Or listen masked frequencies. Why they need it is a mystery. If you need, I can try to write a script that will automatically kick the user when switching to IQ …
-
Hello John! I think the frequency labels should be left in portrait mode. Because the waterfall is long. And in landscape mode, the waterfall is very small. The frequency labels and the top-bar make it even smaller. https://forum.kiwisdr.com/uploads…

Yes. In mobile FireFox is still popup panel. Its strange, that different browsers in different OS show the same javascrypt by the different.
-
@jks, you can test keyboards in different inputmode on different mobile OS using https://inputmodes.com/. Also in function panels_setup() instead of "onFocus", it's better to use "onClick". It will prevent this popup bar. (If usi…
