Sortable by column[edit]

It would help tremendously towards making this collection more useful if it were sortable by columns, especially frequency but bandwidth etc. would be very helpful.

- These features should be coming soon! -admin

MP3 samples[edit]

MP3 isn't the best format for storing signal samples, I think we need to store a WAV file along the MP3, to ease the analysis. --Crossband (talk) 22:09, 21 May 2016 (NZST)


I have two wav samples so far but they are 7 mins long at 44100 hz, almost 40 MB each. Not sure if that will work. I'll try to upload. Ywsia1

You should either shorten them or convert to mp3. If you want to retain the lossless wavs, you can link to a Google Drive or Dropbox with them in the article. --Cartoonman (talk) 23:38, 12 September 2016 (NZST)

I could shorten, but a greater idea is to decrease sample rate. I might be getting a newer SDR that is 820-2 with a better telescoping antenna. That way it may be able to receive better, and I can upload via laptop. It also costed the same as my previous, but now broken SDR that has shorted out, and no longer recieves signals. with the newer one I can receive the cdma2000 better to upload to this wiki.

well... decreasing sampling rate would decrease the temporal resolution of the signal if you plan on using it for analysis. For sound sample its not necessary for temporal resolution, but for raw signal sample it is necessary. --Cartoonman (talk) 08:29, 16 September 2016 (NZST)

Actually I am probably the only one who DOES NOT trust the offline database Artemis. As it leads to an addy site that seems very untrustful to IT people like me....Ywsia1.

Artemis itself is a safe program. Adfly is just used for ad revenue, and you just have to click skip on top. I'm not sure currently of the progress of development on Artemis. EDIT: The 'addy site' link issue has been resolved. --Cartoonman (talk) 06:24, 8 July 2017 (NZST)

Licensing for .csv db, audio and image clips.[edit]

Hi there,

What if any licensing issues are there for incorporating the .csv db, audio and image files into a commercial product? Do not want to use the Artemis application, just the back end files.

Thanks in advance, Michael

All recordings and images from this website are shown and given as-is for educational purpose. There is no licensing for these materials, as they are 'of nature', recordings of an rf environment. Some may claim copyright of some audio recordings on this website, but in my view, audio recordings of an RFRadio Frequency signal is hardly an 'artistic work' that is copyrightable, especially when the said individual likely did not get permission from the transmitting authorities and agents to record said signal. For the legality of recording such signals, use common sense. --Cartoonman (talk) 14:45, 18 October 2017 (NZDT)

Thanks for the feedback Cartoonman.

Any chance you could direct me to a link for current database updates? Do you know how often updates are made/posted?

Or, maybe these are questions I need to ask the Artemis peeps about? If so, I apologize.


Questions regarding Artemis should be directed to Artemis's software developer, Marco on his website. His software's 'data' is just directly sourced from our website. As for a 'current' database, this website is always the most current version of said database, as it gets updated somewhat daily by users and occasionally myself when I have the time. Such changes can be viewed on the Recent changes page on the Navigation box on the far left of this website.--Cartoonman (talk) 13:45, 26 October 2017 (NZDT)

Discord Link[edit]

Hey, I don't know how Discord works, but I believe the link is still up. Should it still be there? Willt (talk)

Yea I was lazy/busy. Took it down now. Replaced link with a mailto: URI. --Cartoonman (talk) 14:37, 27 January 2018 (NZDT)
