[time-nuts] 9390-55108 IRIG

[Rob Kimberley]

It was originally designed to put on magnetic tape for time tagging
telemetry data from the White Sands missile testing base. It can be used for
a number of applications where you need to send time via coax cable to other
devices i.e. time displays, synchronising other timing devices.

Google IRIG-B and get the history.

    The TrueTime GPS receiver and frequency standard I have puts out IRIG-B
as well as 4 each 10 Mhz. signals. What in practical terms is the IRIG-B
(AM, not DC) good for?
