Hamclock 4.10 Up and Running WSL

-
Image
I was able to get Hamclock up and running in Christmas Eve just in time to see the Santa tracker.   Very nice edition to the shack — its a fully configurable kiosk-style application that provides real time space weather, radio propagation models, operating events and other information particularly useful to the radio amateur. I’ve been running Hamclock in a full screen in a Chrome browser window (F11 toggles full screen).  Its  FB to access from my tablet in addition to the host PC on my local private network. With a few commands provided in the step by step guide by W4CAE you can run HAMCLOCK on Windows 10 / 11 using the Ubuntu  WSL. To learn more about Windows Linux Subsystem (WSL), click https://learn.microsoft.com/en-us/windows/wsl/about . My version is compiled and installed using the hamclock-web-1600x960 web server only parameters.  For reference  http://127.0.0.1:8081/live.html .   Use port 8082 for RO interface if you should want to make ...

EdgeOS SQM Smart Queue Management Configuration

Network quality is the biggest issue I’ve had when accessing the Flexradio remotely - via hotel WiFi or the LTE connection on my tablet hotspot.  I see a lot of dropped packets, especially in the RX audio, which causes the audio to become scrambled from the radio,  and generates a lot of snap-crackle-pop in the audio on the tablet.  Performance can be improved by reducing bufferbloat in the router (latency and jitter) and by eliminating network packet fragmentation because of the MTU. I've gotten rid of bufferbloat on my remote network by enabling the Smart Queue Management function in my Ubiquiti Networks EdgeRouter X, 4-Port Gigabit Router.  The ER-X runs EdgeOS and is easy to enable with the basic functions, but with some testing and tweaking of  the additional parameters I've found these settings work best for my network.   Nextlink is my Wireless ISP, and I have a static IP set up. Per the waveforms website, with SQM enabled an EdgeRouter 4 can su...

Update 11/19/23 - Tribute for Bill Crane, SK 10/26/23: https://youtu.be/Znyqq9f93r0?si=bxPV0zVmGN7oWo_u ++ Update August 22, 2022.   I was able to find Bill Crane W9ZN on the air by looking for his spots on RBN .   Took me a while to see the pattern on when and where he's be on frequency, but not only did we make the QSO, we exchanged cards as well!  This is one of my favorite QSL cards that I've collected so far.  Thank You Bill!     73 Chris de WX7V ==================================== Last month I asked a members of the Straight Key Century Club  what was their favorite way to warm up before sending morse code.  I got a lot of input - from, "Just jump right in" to sending the Alphabet and the Numbers 0-9.   My favorite answer is to practice sending Bens Best Bent Wire, with the letters and numbers run together so that the code produced sounds similar to a march.  Apparently this was taught by the RAF,  merchan...
