In the addition to all the good points above another thing that might be worth checking is the coax cables going to your receiver. I replaced one low quality cable with poor shield and center conductor connections and noticed almost 15 dB reduction …

Actually there are some open source projects around using so-called "deep learning 3D convolutional neural nets" for signal classification and speech recognition. For the purpose of audio 2D or 3D spectograms of a very very large number …

Hi Dave, You could have a look at audiorouter (https://github.com/audiorouterdev/audio-router). It works pretty well for what you are trying to do although I am not sure if Windows 10 is supported. I noticed that sometimes the connection fails for …

Tried combinations of the above parameters and this time used a GPS disciplined cw rf test signal. My initial suspicion that the CWN filter pass-band and the decoder center frequency did not match was incorrect and caused by a frequency error in th…
-
Just from casual observation at low levels approx below S3 the decoder seems to default to a center frequency that to me appears different from the 500 Hz center of the CWN filter and this may contribute to the poor decoding at those levels. Unfort…

Quite useful addition Seems that for the display of centre location of the pass band a position further to the right as now is only the case for the IQ mode would be better so it does not get blanked by a extension control window. Never noticed it …

Hi John, The first step you mention would be a good start to limit outside TDoA requests via the extension if necessary to zero. The other one is more drastic of course. Just hope that only Kiwi owners in those places that are concerned about thei…

@N6GN, @G8JNJ I am also in favour of limiting the Kiwi channels available for TDoA service, perhaps with the exception of the administrator. It has been suggested to somehow dynamically show which Kiwis contribute best to the TDoA solutions. While t…

@jks Some observations using v1.207: a. Sampling started but not completed cases. Tried various browsers, cleaning caches, etc but find often the thing that works best in those circumstances is opening a new browser tab. Of course not so convenien…

Hi John, A very minor point with so many items on the to-do list: the map choice either map or satellite on the Kiwi map should probably initially also be carried over to the results pages. Finding a small island in the Pacific with night overlay l…

Indeed version 1.205 seems to help with the TDoA processing. Appears that more often than previous days after using submit "sampling started" is announced but never completed. I tried sampling requests from different Kiwis worldwide with…

Hi Daniel, Not sure if your question about on-line version was related to the CRFS software. If so, I really don't know but looking at their website it seems either DFs, TDoAs or a combination of both is used and available right after processing. …

Really great developments around this extension. I find myself cycling between the computed TDoA maps (and sometimes td plots) to find which sets of Kiwi nodes work best. It might be an idea to show these maps for a brief period sequentially befor…
-
Currently it is a pretty elaborate process to pull in the data and get everything installed and running under Linux and have Octave do the analysis to produce the TDoA maps. For folks using mostly MS Windows it is quite a challenge to get thru the …

Tried out CatSync version V1.11 full version after initially observing it in a sandbox environment and not seeing any suspicious behaviour. It starts up a CefSharpBrowserSubprocess as interface to the selected web Kiwi and listens to Omnirig CAT co…

Hi John, Really looking forward to the possibility of kiwi users to create and share their own extensions. This could be great to test out various ideas and hopefully at the same time reduce your workload..hi

Perhaps this basic morse decoder on sourceforge is worth a look, however not as nice as the Javascript ES6 decoder that John mentioned above. Morseview link: https://sourceforge.net/projects/morseview/?source=navbar Javascript decoder: link: ht…

Hi all, In my location I have serious BCB overload problems and from AM stations closeby. I see signal levels in excess of -8 dbm on the output of a "Trask" amplifier. This antenna amp has a good ground and has an antenna length trimmed b…

Indeed those slanted lines so well visible on the 30 Mhz wide Kiwi display are intriguing. The sweep rates, period and UTC offset of these chirp sounders can easily be determined visually. In addition to the IBP scan and WSPR extensions the ability …

Hi John, There is a small but functional program called KG-DGPS, showing the actual GPS corrections. A couple of years ago the author "KG" JJ0OBZ made a whole series of mostly freeware and well designed speciality decoders, but then unfor…
-
Hi John, It appears the way Martin describes it is indeed the case. I am pretty sure the creator of this non-commercial program would be willing to look into a possibility to interface to KiwiSDR if at all possible and given the some more informatio…
-
Just for information. I was going to try out this rather large CATSync program, but discovered it gives some positives on multi virus scanners, showing a keylogger (trojanspy.MSIL). Probably false positives from second class virus scanners.Although…

In the past I have used DF8RY's CSVuserlistbrowser for control of a Winradio SDR as well as more recently an Afedri SDR. The interface works quite well and has a lot of flexibility manipulating various frequency databases and has a good search and s…
