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.

squelch tail

A burst of noise (a.k.a. "static") heard after a FM radio transmission ends. The random static sound is actually the radio trying to decipher the ambient background noise into meaningful audio. Usually this noise is hidden from the listener with the squelch function on the radio. In typical squelch systems, the audio circuit is turned off if the radio isn't receiving a signal of a certain minimum signal strength. The squelch tail occurs when the transmission has just ended and the radio circuitry doesn't respond quite fast enough. This is remedied by systems like STE or Squelch Tail Elimination by Motorola which send a brief subaudible tone right before the end of the transmission so that the audio circuit turns off before the modulated signal ends. Creative use of CTCSS like turning off the tone generation circuit on a repeater before the repeater tail will work for radios using tone squelch on both transmit and receive.

My VX-150 has a very long squelch tail.

unsexy

I would have to disagree with that statement, because there are plenty of sexy irish people out there, and I am one of them. Czechsmix has no idea what he is talking about sense irish (red) hair would be probably the sexist out there.

Czechsmix has no idea what he is talking about.
