      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.

      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.

      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.
