A cheap WWVB watch will do the trick.

Subject: [time-nuts] Setting Time on WSPR Radio Transmitter

Hi:

I'm experimenting with a WSPR beacon transmitter and part of how it works depends on pushing the start button at exactly
2 seconds past the minute.

Background By using a digital mode where the signal bandwidth is narrower than the standard 300 Hz to 3,000 Hz voice bandwidth the signal to noise ratio can be improved thus working where voice will not work.



The problem is the transmitter (and the start button) are out in the forest where the antenna is located.

SotaBeams, who make the WSPRlite transmitter recommends using http://time.is/ which seems to be accurate on my cell
phone but not on my desktop running the stock NTP.
Can someone comment on time.is?

Have Fun,
