Open Hamclock Backend Project Status

Below is a list of Open Hamclock Backend Project updates. All releases and major changes are listed here so you can keep track of what is happening with the project. Come back to this page on a regular basis, especially if you are running your own version of OHB. If you have your HamClock directed to the OHB backend server (ohb.hamclock.app:80) you will get these updates with no action necessary.

OHB V1.0.11   04/11/2026

OHB V1.0.10   04/08/2026

  • moon supported in satellites for EME folks
  • refresh of latest active satellites
  • more frequent updates of drap map for smoother refreshes
  • initial support for old ESP-based devices that can’t run 4.22

OHB V1.0.9   04/06/2026

  • WWFF was dropping spots without modes, now included
  • DRAP map colors were a little aggressive, tuned in more accurately
  • dxpeditions are hard since there’s no clean API, improved processing for better accuracy
  • wx map rendering accuracy improved

OHB V1.0.8   04/05/2026

  • voacap map generates faster; address highest resolution then selecting 3x zoom could timeout

OHB V1.0.7   04/03/2026

  • switch Bz to use new NOAA endpoint
  • switch solar wind to use new NOAA endpoint
  • increase the rate at which Auora maps are refreshed
  • change DRAP maximum based on extremes we saw today
  • Aurora had slight artifact at equator which is resolved
  • NASA’s SDO images and movies came back. We use suntoday as backups
  • increase docker timeouts when installing for slow systems
  • visiting ohb.hamclock.app redirects to https://ohb.works

OHB V1.0.6   04/01/2026

  • P-IP now displays your remote IP instead of “No Network”
  • fixed upgrade-me when the filename has version in it, if you run your own OHB
  • Kp was broken by NASA changing their json – adapted to new json
  • drap source is down. to be like CSI, the data repeats and generates a flat line
  • if you run your own OHB: rm -f /opt/hamclock-backend/htdocs/ham/HamClock/drap/*

OHB V1.0.5   03/31/2026

  • Bug with by- and of- calls in pskr
  • Additional fine-tuning of aurora maps
  • New provider for map fly-over temps
  • Fix rbn for rotating API keys
  • Fix recently broken remote IP display

OHB V1.0.4   03/29/2026

  • Aurora Maps look much better and smoother, like ClearSky
  • Speed improvement generating all of the VOACAP maps

OHB V1.0.3   03/26/2026

  • DST was not implemented for DE timezones that expected it

  • Dynamic generation of the version number for HamClock’s
  • Support for HamClock beta version schemes as HC implements them

OHB V1.0.2   03/24/2026

  •  A new contributor, KR8X, fixes that include missing parameters in the VOACAP map calculations
  • Speed and memory improvements that enable 2x and 3x zoom to work for very large resolutions
  • Aurora map fix for little blob at equator

OHB V1.0.0   3/20/2026

  • new server

OHB V1.0.0   3/19/2026

  • dateline and north pole distortions resolved for voacap maps
