[time-nuts] Navsync CW25 rollover

[Mark Sims]

The Navsync CW25 crapped its pants when rollover occurred.  It (and a lot of other Navsync devices) have a known firmware bug where they stop tracking sats if the week number is 0.   Sure enough, at zero hour, all the sats disappeared.

Conner Winfield has firmware updates for the problem receivers.  The updates are in .rar format files that require winrar v5.x to unpack.  See:

So, I uploaded the new firmware... which went well.  The new firmware does enable the ability to set the satellite elevation mask.    At first the new firmware was still not tracking satellites.  It took 10 hours before it started working.
