[VHFcontesting] Maidenhead grid locating for Rovers, now GPS time sync...

[Ron Rogers]

We use Tardis 2000 along with a USB GPS module on the 1 small Dell PC that
operates as the time server and server for our logging program for all of
the W4NH Multi-op PCs.

I use a Raspberry Pi with an Adafruit GPS
<https://www.adafruit.com/product/746> - I run dnsmasq, gpsd, and chrony
with PPS from the GPS.  This gives me accurate (sub-microsecond) time and
accurate-enough (WAAS, so sub-5M accuracy) position, as well as providing
DHCP.  I configure my laptop to get its time from the pi (I set windows to
sync its clock every hour), and Roverlog is smart enough to talk to gpsd
for the position data.  If I happen to want more than one laptop, all I
need is a small Ethernet switch and I'm good to go.
