World Time

Welcome to the NEW look of my web site!
Finally, I'm finding more time to do what I want to do. Like Ham Radio! Getting close to retirement I'm excited to be involved more in my hobby. Sure, time flies when you're busy. Not to much fresh content, mostly landfill. That will change shortly, as I work to improve the look and feel of the site.
The template I used for the site is mostly a single static web page. The advanced CSS and javascript animate the pages. I will be adding a database to access logbook data and content management.

Ecuadorian Military Navy time and frequency standard station transmits one-second tone-pulse time-markers and local time announcements in Spanish between 19:00 to 07:00 UTC from the Instituto Oceanográfico de the Armada in Guayaquil, Ecuador. The one-second tone-pulse time-markers are 600 Hz the first 15 minutes, 400 Hz the second 15 minutes, and are omitted the last 30 minutes of each hour. Station identification is transmitted every hour between 40 minutes and 59 seconds and 59 minutes and 40 seconds. Transmissions are difficult to hear because of strong interference from Amateur Radio stations. |

Double Second
Time Markers Other International time and frequency standard stations share 2500, 5000, 10000, and 15000 kHz. Sometimes they can be heard when the skip distance is long. One of those stations is BPM in Pucheng,China, which is operated by the Chinese National Time Service Center (NTSC) (Shaanxi Astronomical Observatory, Chinese Academy of Sciences). BPM usually broadcasts Coordinated Universal Time (UTC) like WWV and WWVH do, but during minutes 25 through 29 and 55 through 59 of each hour BPM transmits UT1 instead. UT1 varies up to 0.9 second from UTC and the time difference can be either positive or negative. As a result, BPM's time blips during those minutes normally lead or lag WWV and WWVH time ticks. BPM uses Chinese female voice identification during the last minute of each hour. | |||
