This comes from the latest RadioWorld NewsBytes:
================================================== ================================ The National Institute of Standards and Technology is considering setting up a U.S. East Coast low-frequency radio station broadcasting NIST time in binary code format to complement the present NIST 60 kHz, WWVB broadcast. "The proposed new East Coast broadcast will operate with the same time code format as the present WWVB signal, however at a different carrier frequency, potentially at 40 kHz," John Lowe, the WWVB station manager, told RW. Eight years ago, the power of the WWVB broadcast out of Colorado was increased from 13 kW to 50 kW and has since been increased to 70 kW, he said; but "even at this power level there are locations on the East Coast that have difficulty consistently receiving the time code." Some advocates say an East Coast broadcast would make the time code easier to receive, increase sales of radio-controlled clocks and spur development of radio-controlled timing devices in appliances and other consumer products. Lowe is seeking comments about the possibility and asks that readers write to him. His e-mail address is . ================================================== ================================ I think this would be very welcome though it would do nothing for those radio-controlled clocks already out there. I also wish that all newly-designed shortwave radios would feature a radio-controlled clock that could show two time zones - the local one and UTC. Best, Joe |

Best, Joe JA, Why not simply add another 50KW Transmitter and a Directional Antenna pointed at the North East / New England Region at the present WWVB Transmission Site ? Or pay half of the cost for Canada set-up a WWVB type Boardcast Transmitter on their side of the Border somewhere near Ottawa. It would serve their geographic needs and our East Coast needs too ~ RHF |

Best, Joe They could put the new station on 60 kHz as well. If they can't get them adequately synchronized they could alternate every 30 minutes or whatever. This would avoid everyone having to buy new watches. Any commercial entity who really needs accurate time switched over to GPS a decade ago. |

I wonder if there really is demand for it. Being outside of the U.S., I can't say for sure, but I thought that GPS location was required in cell phones sold there (not here). If that's the case, it would be likley that cheap GPS clocks could be made, and they are not affected by the noise commonly produced by many modern electrical/electronic devices. For the home and many businesses, a WiFi or ethernet clock synchronized using NTP (Network Time Protocol) would be preferable as more and more people have broadband Internet connections which are on all the time. Another option would be to insert time signals in cell phone control channels, if they are not already there. Cell phone receivers are cheap, would not require a service contract as they would never transmit anything, immune to most RFI, and cell phone service covers almost all of the U.S. and most other countries. IMHO it's a case of trying to extend a service that is rarely used (how many people actually have radio synchronized clocks?) and can be easily replaced with much newer and better technologies. I understand that this would require the few people that want synchronized clocks that have not gone to GPS or NTP already to buy new ones, but isn't that the way things are done these days?

can't say for sure, but I thought that GPS location was required in cell phones sold there (not here). I think cell phones are normally located through the cell tower network, not through GPS. I could be mistaken. If that's the case, it would be likley that cheap GPS clocks could be made, and they are not affected by the noise commonly produced by many modern electrical/electronic devices. You do realize that GPS does not work inside most buildings? In fact the main selling point of longwave is that it goes through everything (even underground), isn't it? |

I have about 6 of them. They run for a couple years on a single AA battery. No wires. |

GPS only works in a clear area with good view to most of the sky (it's even a little less accurate if you're driving through a steep sided canyon). |
