Talk:Signal Identification Guide
Sortable by column
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
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.
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)
X-10 AKA X10 Powerline and RFRadio Frequency frequencies and protocols
I did not find any information on X-10 in the searches here. Information from Wikipedia: 
Power line carrier control overview
X10 modules: The interior of an appliance module (note the impulse relay on the left) and a lamp module (note the TRIAC and heat sink) Household electrical wiring which powers lights and appliances is used to send digital data between X10 devices. This data is encoded onto a 120 kHzKiloHertz (kHz) 10^3 Hz carrier which is transmitted as bursts during the relatively quiet zero crossings of the 50 or 60 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). AC alternating current waveform. One bit is transmitted at each zero crossing.
The digital data consists of an address and a command sent from a controller to a controlled device. More advanced controllers can also query equally advanced devices to respond with their status. This status may be as simple as "off" or "on", or the current dimming level, or even the temperature or other sensor reading. Devices usually plug into the wall where a lamp, television, or other household appliance plugs in; however some built-in controllers are also available for wall switches and ceiling fixture]
RFRadio Frequency protocol
To allow for wireless keypads, remote switches, motion sensors, et cetera, an RFRadio Frequency protocol is also defined. X10 wireless devices send data packets that are nearly identical to the NEC IR protocol used by many IR remotes, and a radio receiver then provides a bridge which translates these radio packets to ordinary X10 power line control packets. The wireless protocol operates at a frequency of 310 MHzMegaHertz (MHz) 10^6 Hz in the U.S. and 433.92 MHzMegaHertz (MHz) 10^6 Hz in European systems.
I would like to be able to use my recent RTS-SDR to monitor the X-10 signals in my home, to try to improve their reliability. I'd like to sniff out the sources of interference, etc.!
I KNOW X-10 is OldSkool, and WiFi will become the new transport for Home Automation systems. But THIS Week.....
There should also be a rule stating here that fake signals are not allowed UNLESS they are/were legitimate, and need a sample or waterfall. Example: Discontinued or requested signals. --Yalek W (talk)
Both a width scale (bandwith) and vertical scale (time) would help make comparisons of signal appearance helpful. Or, ensure they are identical in all images.
