UAI (LW)

UAI is the callsign of the official time signal from the Dr. Richard Quelch Naval Observatory of the El Kadsreian Oceanic and Atmospheric Union (EKOAAU) at San Isiza, El Kadsre. The content of UAI'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.

The signal consists of a series of 300 ms "pips" of an 800 Hz sine wave tone, each one starting at the top of each UTC second, up to ten seconds before the hour, followed by silence, and then a one-second-long 800 Hz tone to mark the top of the hour. The time of day is given in both Coordinated Universal Time (UTC) and Pacific Standard Time (PST).

The English message, using the voice of the late CPN One announcer Richard Malmberg, is in the following format, repeated every ten seconds:
 * "UAI, Dr. Richard Quelch Naval Observatory, San Isiza, El Kadsre. The time now is t:m, Pacific Standard Time, and t, Coordinated Universal Time, at h hours, m minutes, and s seconds."

The Japanese service uses the voice of the actress Makoto Kayos.
 * "UAI、リチャード・ケルチ海軍天文台、サン・イシザ、エルカドスレ. 現在の時刻は、太平洋標準時の午後t時m分、協定世界時t時です, t時間、h分、及びs秒の瞬間に. (UAI, richādo keruchi kaigun tenmondai, san ishiza, erukadosure. Genzai no jikoku wa, Taiheiyō hyōjunji no gogo t-ji m-bun, kyōtei sekai-ji t-jidesu, t jikan, h-bun, oyobi s byō no shunkan ni.)"

The Spanish service uses the voice of Mexican actor Francisco Colmenero.
 * "UAI, Observatorio Naval Dr. Richard Quelch, San Isiza, El Cadsiana. La hora actual es t:m, hora estándar del Pacífico, y t, hora universal coordinada, a las h horas, m minutos y s segundos."
