full quieting

A phenomenon on FM transmissions where the incoming signal is sufficient to engage the receiver limiters - thus eliminating the noise due to amplitude fluctuations.

sub rosa

Translated from Latin, this means "under the rose" and is a term frequently used for surveillance but can also mean any type of undercover or discrete investigation. We provide sub rosa/surveillance services both to private parties and to commercial firms.

see pirate radio for where i used this word.

EPIRB

Emergency Position Indicating Radio Beacon

The EPRIB (or "e-piryb") is pretty much an uber-ELT that transmits a radio signal on a frequency somewhere around 406 MHz. This signal contains information regarding the location of the signal (usally a downed aircraft or ship in distress). Satellites (known as SARSAT pick up this radio signal (as well as ELT signals) and relay this information to centers like the AFRCC. Search and Rescue is then dispatched to search and rescue agencies such as The Civil Air Patrol and Coast Guard.

Because the captian of the sinking fishing boat had bought an EPIRB for his boat, the Coast Guard was able to find and rescue him quickly.

spread spectrum

A signal struc­turing tech­nique that employs direct se­quence, frequency hopping or a hybrid of these, which can be used for multiple access and/or multiple func­tions. This technique decreases the potential interfer­ence to other receivers while achieving privacy and increasing the immunity of spread spec­trum receivers to noise and interference. Spread spec­trum generally makes use of a sequential noise­‑like signal structure to spread the normally narrow­band informa­tion signal over a relatively wide band of frequencies. The receiver corre­lates the signals to retrieve the origi­nal informa­tion signal (NTIA)

Normal scanners cannot get spread spectrum transmissions.

I cannot believe this is the only true definition of Fuel on this website.

20,000 leagues under the sea

I do believe it is 20,000 fathoms under the sea.

Jules Verne may have perdicted nuclear technology, but he knew nothing about nuatical measurement.

transmitter testing

When I'm bored, I go "transmitter testing". This generally refers to me picking a random VHF frequnecy and transmitting music over it. Because I have a Vertex VX-150 as well as a 35-watt VHF amplifier attached to it the range is about 20 or miles, depending on if I am transmitting at full power or fractional power levels. I like to chose frequencies that are not being used, generally its a business radio service frequency or Marine VHF channel. I have however, transmitted over weatheradio (162.400 to 162.550 MHz) channels are that really pisses people off.

This is all, of course, illegal.

Guy who lives next to me: "How come all I hear on my weatheradio is Jimi Hendrix and Men At Work?"

Me: "I'm just transmitter testing"
