Actually I found that using SAS this binaural effect is quite pronounced and helpful when listening to closely separated CW. To prevent SAS locking on to the strongest signal and wandering around all the time, I usually insert an external carrier s…

Interesting addition in v1.554 to the TDoA extension where it is now possible to show the results of previous runs on the map display. Makes it easy to visually compare the results of several runs with the same or different kiwi nodes and spot outl…

Quite agree with Marco's and Alsace's comments and that it would be possible to game these wideband SNR values intentionally. A site that I found quite interesting is https://rx-tx.info with screen shots of almost all public web SDRs. When updated…

Hi Marco, Indeed your earlier work on showing these snr's on a map interface for 4 bands inspired me to create something similar plotting this information for 20 selected Kiwis in 4 longitude bands. Although I started out with using microkiwi waterf…

Hi Eric, Turns out that microkiwi_waterfall.py has been last updated 3 years ago and is still a Python2 script. If you can run it that way it will print the average snr for the zoom level you selected. You could make a time plot of that e.g. when ex…

@circuitmike After trying several wifi dongles unsuccessfully with debian 10, I found an older TL_WN 722N and it showed up right away with the correct id and without need to find specific drivers. After that I only needed to use connman which is al…

Hi Marco, Thank you for the response and indeed it might very well be a Hamlib Net rigctl issue. I did get somewhat better frequency following after changing 'settimeout' to 9 sec in utils_supersdr, this of course at the expense of the response tim…

Hi Marco, CAT control from Icom-725 checked on RaspberryPi3 / debian Linux 10 (buster). https://forum.kiwisdr.com/uploads/167/FDZZP0LP4ORU.png Finally had a chance to try CAT control from a borrowed and dusty Icom 725 rig. So the CAT control works …

Tried this script but only the symbols without the data appear. I ended up using a widget from time.is ( https://time.is/widgets ) for sunrise / sunset. Since I already use Stats area for a couple of other links, I placed the widget in the addition…

Hi Bob, Thanks for looking that up and I will try this out later. 73 Ben

This is already a quite old discussion and I wonder if someone still has this particular html snippet for sunrise sunset calculation available and would be willing to share it as a zip file or txt file. Thanks, Ben

@jks Kiwi working again after upgrade to version 1.538. I encountered a problem when adding band bars and have sent an email to support. Extracting a bunch of frequencies mainly from UDXF reports and running an automated scan for a couple of hours…

Hi John , Very interesting find and development of this new selcall decoder. Just like Martin I also wonder about the Codan and Barett selcall signals some of which probably also carry position data although likely scrambled. Looking at UDXF reports…

Hi Shane, The first two letters stand for the ISO-3166-1 ALPHA-2 country code. The letters after that are often just made up and necessarily kept short. Some are probably easy to guess like UNHCR or AF for Air Force, NV for Navy, POL for Police. Ot…

Hi John, Noticed just a single case of a 4.N message over a 3hr period. https://forum.kiwisdr.com/uploads/158/W3XQ8ME54CGP.png 73 Ben

[DSC decoder] Just as a note: like some other extensions e.g. HFDL, the DSC extension only decodes correctly if tuned to the DSC center frequency, which should be taken care of if the GPS produces fixes. Without GPS a manual frequency correction ma…

[DSC decoder] The DSC decoder in the NAVTEX/DSC extension works quite well. A cursory check against YADD (Yet Another DSC Decoder) running off the Kiwi audio shows the number of completed message decodes almost equal with a slight advantage to the …

Hi Martin, About a scan list and recording did you try Christoph's kiwirecorder.py scan option addition? It does most of what you are looking for. https://forum.kiwisdr.com/index.php?p=/discussion/comment/13136#Comment_13136 73 Ben

There is some description on how the narrow band SNR is derived in Simon's SDR console app at https://www.sdr-radio.com/s-meter This is done in the frequency domain for the IQ data within the bandwidth of the selected mode and the process is similar…
-
I can confirm that Select band and custom colours defined in config.js are restored with the v1.504 release. Thanks, Ben

Hi Marco, Upon closer inspection today i do see that moving to the bottom of the display the readability becomes normal, so then it points to a LED monitor issue in my particular case. It might be an idea to cater for different monitor and graphics …
-
Hi Marco, I sent you a pm message about the font situation. The RPi 3 does ok with Supersdr and Digiskimmer running. When adding more than 2 browser windows the pi graphics have difficulty keeping up.
-
Hi Marco, This new version works well and so far had no chance to try out the rigctl functionality. One thing I can't seem to get right is the readability of display fonts even though I tried different monitor settings and even tried to change the f…

Hi Christoph, Indeed with the fast agc and a higher squelch threshold the scan recording works great. This of course keeping in mind that the squelch only trips on signal level and not tries to check for presence of voice or some digital mode. Th…
-
Hi Christoph, Thank you for creating this scan option. Just for feedback I notice the following: When trying, it looks that the squelch opens and the wav recording starts all right, but never closes. Checking with log level debug enabled a "squ…

Also noticed this and it first started around v1.462,463 if I remember correctly. On a local network easy to reboot, from an outside connection that might be problematic depending on being able to reach the Kiwi server via ssh. Likely a power cycle…

The flight markers, colour fading and "clear old" are already good. In certain areas the screen can fill up quickly with almost overlapping markers and perhaps a radar style marker can be considered, which is less conspicuous. Examples sh…

John, The MUF3000 svg image comes from the prop.kg2c.com website Andrew, KC2G and is generated with a repository found at github https://github.com/arodland/prop .The image is aggregated from the Digsonde network and refreshes every 5 - 10 minutes.…
-
I couldn't resist to try an overlay of the HFDL extension map with the MUF3000 data derived from the Digisonde network. Both are almost real time and show some interesting aspects of the prevailing HF propagation. 73 Ben

Interesting to see the active frequency table presented colour coded on a map. The limited screen real estate is still manageable on a 13 inch laptop using the x and y keys. With aircraft positions shown as well the display could become quite crowd…
