YVTO
Encyclopedia
YVTO is the callsign of the official time signal
from the Juan Manuel Cagigal Naval Observatory in Caracas, Venezuela
. The content of YVTO's signal, which is a continuous 1 kW
amplitude modulated
carrier wave at 5.000 MHz, is much simpler than that broadcast by some of the other time signal stations around the world, such as WWV
.
The methods of time transmission from YVTO are very limited. The broadcast employs no form of digital time code. The time of day is given in Venezuelan Standard Time
(VET), and is only sent using Spanish language
voice announcements. YVTO also transmits 100 ms-long beeps of 1000 Hz every second, except for thirty seconds past the minute. The top of the minute is marked by an 800 Hz tone.

Amplitude modulation
Amplitude modulation is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent...
