[bars] WSJT-X tip

[Juan Jiménez]

Most everywhere you don't have wired internet you usually have cellphone
coverage. I use the hotspot on my phone to connect to my computer, and it
then picks up the time as usual from the NTP server. Since i don't have to
pay for the hotspot, I allow others around me to do the same if i am in a
group. A GPS puck will do the job, I suppose, but sometimes you are inside
and it can be a problem seeing the available GPS satellites in the
constellation.

Also, most computer hardware clocks these days are VERY accurate. If you
sync before you leave home there is little chance the clock will drift any
significant value.
