      HOW IT WORKS
      When a user connects to www.time.gov on a computer or mobile device, the Javascript in the client's browser checks the local clock on the device and then requests the time from a NIST server, which has been synchronized with UTC(NIST). When the packets containing the NIST time stamp arrive at the client's browser, the device clock is checked again and compared to the first check of the local clock. The result is a measurement the round-trip delay of requesting/receiving the time stamp. It is estimated that one-half of the round-trip delay happens in each direction. The time on the clocks shown on the web page have been corrected for the estimated one-way path delay of the timestamp from the server to the client and the server delay. Your device's clock is also shown, with the error compared to NIST time.

      What would you buy with $10,000

      Just curious what people would put on their wishlist if they were given a US $10,000 gift certificate to buy kit or single item to add to their shack? What would you spend it on??

      WWVB clocks

      K3MRI posted a topic in Ham topics in general,

      I just bought two analog WWV clocks. I'm not having great joy. In trying to debug, I came across an interesting manual published about a decade ago by the Federal Government. It is a recommendations manual for manufacturers. I thought I would post it because it offers interesting insight into how the WWV system works.

    • How was Field Day 2020?

      How was Field Day 2020?

      K3MRI posted a topic in ARRL Field Day,

      How did you fare during Field Day 2020? Did you meet up? Did you operate portable? Did you go 1D?

      As for myself, we ended up in the field. I operated with the Randalstown/NIH group at Washington Monument State Park. We operated under N3IC as a 3A. We practiced mask-wearing, most of us, anyway. We did have one rogue, but he was respectful of distancing. I feel confident that we were safe.

      Setup-wise, I attempted to setup my 40-meter, four-element, wire beam but I was not as successful as I would have hoped. Many lessons learned for next year 🥴

      We are Main Trading Company. We are a real brick and mortar retail store located at 2707 Lamar Ave in Paris Texas (about a hundred miles North East of Dallas). We are Christine and Richard Lenoir. 

      We Started in 2009 when Richard Lost his job in sales due to a stuggling economy. We Started selling on ebay. We would drive to DFW and bring back small pick up loads of surplus and closeouts. Our neighbors were really proud of us when we received our first truckload delivery at our home! In just a few short months the volume got out of hand and our living room and patio looked like a warehouse. We rented a small store front in Beautiful downtown Paris Tx in June of 2009. We out grew that location and moved across the street to 139 Bonham st. In January 2010. Times got even tougher when Christy lost her job as a radio announcer. She came on full time as well.

      HC/STAFF posted a link in Weather and Climate,

      Craig left Seattle, sailing down the West coast of America for the first time in August of 2011. That trip ended up lasting one year, returning to Seattle via Mexico and Hawaii. A second trip lasted three years, sailing from Seattle to Mexico, French Polynesia, Niue, Tonga, New Zealand, Tonga, Fiji, New Zealand and then back to Seattle, again via Hawaii.

      While out cruising, and using a variety of GRIB viewers on a regular basis, Craig had become dissatisfied with what was available. With a background in Computer Graphics and Computer Science, and with 20 years of professional software development in those areas, he felt that there was a possibility of creating a new, modern GRIB viewer that would be able to be much more informative while being highly responsive.

      Craig started work on LuckGrib while sailing on his yacht, s/v Luckness, in New Zealand during December, 2014. Version 1.0 of LuckGrib was released on the Apple Mac App store in early August, 2015.

      LuckGrib takes full advantage of the multiple CPUs offered by modern hardware, as well as the high performance graphics hardware they contain, their GPUs. By efficiently utilizing the available hardware, LuckGrib is able to produce high quality renderings of the weather, in real time. GRIB files are loaded almost unbelievably quickly. When stepping between different time intervals in a GRIB file, the changes are animated at a high frame rate, yielding smooth transitions. All of this speed and quality helps you to understand the GRIB file content and how it changes over time.

      My Medic

      HC/STAFF posted a link in Gear manufacturers,

      Not all beginnings start with happiness. A tragic accident that took the life of a family member was the motivation that started MyMedic. Several years ago a normal day turned dark after a car accident occurred. Bystanders without First Aid equipment or training watched for 40 minutes as a family member of ours bled to death. That’s how long it took EMS services to arrive on scene due to the remote location the accident had taken place. Help is further than you may think.

      As a family we came together and started MyMedic with one objective in mind, to save lives. Our goal is to prepare everyone with equipment and training for the unexpected emergency.

      We discovered that most people are not prepared for emergencies. It’s an unfortunate reality. Life can be gone in an instant, but if you had the power to prevent a loss, you would take it in a heartbeat. Whether you’re driving to and from work, enjoying the great outdoors, or staying home, the solution is peace-of-mind knowing that you have instant access to a MyMedic First Aid Kit.
