      The signals listed on this page are used by and sometimes created by amateur radio enthusiasts and operators, including many experimental digital modes. You can find plenty of these signals in amateur frequency bands.

      Click the name of a signal to see more detailed information, possible decoding, and additional sound and waterfall samples.

      https://hamprojects.wordpress.com/2020/09/06/raspberry-pi-for-ham-radio/
      I'm not sure if this topic has been covered elsewhere.
      The above link provides a set of tutorials on virtually every aspect of RPi use by hams today with emphasis on setup and use of a variety of common apps such as WSJT-X, FLDigi, etc.  Including discussion of SSH, Putty, etc.
      It is truly an A to Z tutorial.  I highly recommend downloading all the sections, seven in all; ~15MB.
      If you have never powered a RPi, or plugged in a mouse, this will get you going.  If you are a power user (not me, I'm just learning!), you will find some new and challenging applications.

    • The Official U.S. Time
      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
      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 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 🥴
