Just discovered this site. It is a fascinating topic of how we communicate efficiently, reliably and securely. I will be exploring the site very much. Very interesting. Thanks. 2020 August 17th 10:57 UTC

Genuinely awesome site, both in organization and content. Will take the mystery out of the odd collection of signals that have puzzled me for years when exploring the bands. Many thanks for your efforts!

A very useful Database, many thanks.

I would like to see a Category for Electromagnetic Interference (EMIElectromagnetic interference / RFIa specific subset of electrical noise on the Electromagnetic interference (EMI) spectrum) signals added, please.

Such as HDMI (already in the database), switched mode power supply (a representative sample, or 2), Ethernet, central heating Boiler(Gas), TV emissions (LO, harmonics, etc), and so on.

It would make the identification of interference sources in my house a lot easier :-) Once I can work out how to do it I can provide samples, mostly unidentified as yet :-(

Regards, Ed

Hello, I've captured a a new signal - at least to me it is - on UHFUltra High Frequency (300-3000 MHz). This was present for several days and has since disappeared. Please refer to this link at Vimeo for a sample. You may have to increase the volume. I'd like to get anyones thoughts on this.

6780kHz definitely needs a sample/pic and more information.

4095.7kHz is the Desert Whooper. https://twit...704567304208

Please mark WLO in the marine section in red. That station has been gone for years. In the military section, MIL-STD-188-110 Appendix A should be in green. While the US has moved from this mode, other countries are still using it. In addition, it's used during Armed Forces Day in the US

There are still many station like WLO, with the FSKFrequency-Shift Keying idling and 3 letter morse ID. I think it should be renamed, but I am not sure what it should be called

Ya, we've been meaning to fix this for quite a while. I will bump it up in priority.

There are still a few maritime stations that use SITOR-A but their days are numbered. The others have gone to PACTOR

Hi guys. Since I havent been able to leave a comment here, im going to do so in a more formal fashion.

Just as a fair warning to all who are paerticipating here, I will be adding on to the main page to provide some policies that I have been trying to get on here with Cartoonman's permission through the use of the trello I have up, that will be tailored at how we need to ensure this wiki's validation at sources, and its pages. This is very big because this will help clear out a lot of junk that has been left behind. For example, I will be spending more time this week, hopefully, moving unid signals to the ID's section, ID signals to the UNID section. Some pages ive seeen are very misleading, or were never formed. So it would be best if that happened.

Not only this, but there will also be additional policies targeted on how you should post signals.
