Status[edit]

Reduced activity expected from January to August.

New Sigidwiki Server upgrade is on hiatus until further notice.

On the agenda:

  • Modulation section, which will give an in-depth analysis of different modulation techniques used by signals to transmit data.
  • SDR section, giving information of the capabilities of SDRs in the market today.
  • Reworking the active/inactive categories.
  • New signal entries, as always (backlog of >25+ signals right now, give me time ok)
  • Rework and improve inadequate signal entries, an ongoing venture.
  • Look into using gfycat plugin for motion-based waterfalls for a richer experience.
  • Considering a references/links section for very valuable websites with relevant information.

The below on page http://www.s...ers_Stations is simply wrong. The first articles appeared in Monitoring Times and even PopComm acknowledged that. A single person mobile DF'ed both locations (I should know). Also the 2nd part about telephone wire pair is totally bogus and no article that I am aware of ever speculated that. The arrived at the transmit site via microwave on a 1.7 GHzGigaHertz (GHz) 10^9 Hz frequency (which was not published).

"Several articles in the radio magazine Popular Communications published in the 1980s and early 1990s described hobbyists using portable radio direction-finding equipment to locate numbers stations in Florida and in the Warrenton, Virginia, areas of the United States. From the outside, they observed the station's antenna inside a military facility, the Warrenton Training Center. The station hunter speculated that the antenna's transmitter at the facility was connected by a telephone wire pair to a source of spoken numbers in the Washington, D.C., area."

Anonymous user, First off you state that " (I should know) " and you are who ? Secondly "and no article that I am aware of" - so you admit you dont know it all. This is a wiki feel free to add your contributions and fact checks with backing evidence since " you should know ".

I'm not sure what he is referring to. If he refers to the information at the bottom of the page of Numbers Stations, that information was taken from Wikipedia itself, so if there's any disagreement, go to Wikipedia.

Thanks Cartoonman! I thought it was but wasn't sure!

ARQAutomatic Repeat reQuestAutomatic Repeat Query def: Three characters are transmitted by Information Sending Station (ISSInformation Sending Station in an ARQ link (The station sending information to the recipient). Usually the signal that's longer in duration than the short RQ (Repeat Request) bursts from the IRS.). Takes 210 milliseconds. The ISSInformation Sending Station in an ARQ link (The station sending information to the recipient). Usually the signal that's longer in duration than the short RQ (Repeat Request) bursts from the IRS. then waits 240 msmilliseconds (.001 of a second) for a response. Information Receiving Station (IRSInformation Receiving Station in an ARQ link (The station receiving information from the ISS.

If they do, then the IRSInformation Receiving Station in an ARQ link (The station receiving information from the ISS.

If they don't, then the IRSInformation Receiving Station in an ARQ link (The station receiving information from the ISS.

At the beginning of the next frame, the ISSInformation Sending Station in an ARQ link (The station sending information to the recipient).
