Open HamClock Backend - Another HamClock Server Option

Udo Koch, N0LSR has great support for the Inovato Quadra and is marketing the same hardware as Inovata has stopped its sales due to health issues.  At https://www.n0lsr.com/, Udo discusses the future of Hamclock and gives a rundown of the currently three dominant Hamclock related projects: Classic HamClock, Open HamClock Backend (OHB) which Udo supports, and Open HamClock, a browser-based site (that offers an alternative presentation to the traditional HamClock theme.

Classic HamClock: This project is the product of Bruce Edrich, W4BAE and his team of volunteers.  I've profiled the Classic Hamclock backend extensively in my Feb. 25-26 posts and had been running that backend version for a few days.  The current version is still being tweaked (as are all of the projects) and I like it.  However, RandomWire states "that there are a lot of reports that devices are locking up and will require a full factory reset to come back.  I therefore caution not to use the hamclock.com server solution and rather go with OHB" (see below).

Open HamClock Backend (OHB): OHB is from the efforts of Brian Wilkins, KO4AQF and his team.  Based on Udo's suggestions, I'm now trying that backend and I have to say that I really like the map renderings.  The only issue I've found so far is that the VOACAP window (as opposed to the VOACAP related maps) does not seem to populate for the moment, but this may simply be a current propagation issue.  According to Udo, the OHB server has the advantage of being open sourced and not being centrally based.  OHB pulls data in directly from the sources.  Udo provides detailed OHB changeover instructions at: https://www.n0lsr.com/tipsandtricksRandomWire also opines that OHB is the most stable and advanced solution and is ready for prime time.  

Open HamClock: I've run the third option, Open HamClock for a couple of weeks.  This option is browser based and should not be confused with Open HamClock Backend (OHB)I like the information it provides, but have issues in trying to customize it to my liking.  It also radically differs from the traditional HamClock theme which I actually prefer.
