ClockWatch Radio Sync allows you to test to see if the program is able to communicate with
WWVB receivers data port through the computers serial port. After the connection to
the receiver is opened, the test screen shows the raw data coming from the
displays the information parsed from the raw data, and shows the current
readability of the broadcast.
The WWV test screen is useful in verifying
1) Receiver is working,
2) the cabling is correct, and,
3) the location and orientation of the antenna is correct.
