description Heathkit GC-1000A Overview

The Heathkit GC-1000A is an updated revision of the famous Heathkit Most Accurate Clock, a digital timepiece kit from the 1980s that synchronized with NIST WWV radio signals in the USA.

help Heathkit GC-1000A FAQ

What is the Heathkit GC-1000A Most Accurate Clock?

It is a Heathkit digital clock that uses a radio receiver to synchronize its time with NIST broadcasts. The GC-1000A is an updated version of Heathkit's Most Accurate Clock from the 1980s era.

How does the GC-1000A synchronize with WWV?

The clock receives NIST WWV time signals over shortwave radio rather than depending only on a free-running crystal oscillator. WWV is the time-signal station operated by NIST in Colorado.

Does a Heathkit GC-1000A need an antenna to work properly?

Yes, the radio-synchronization feature depends on receiving a usable WWV signal through its antenna system. Buildings, local electrical noise, distance from Colorado, and propagation conditions can affect reception.

Is the GC-1000A the same thing as a modern internet or GPS clock?

No, it is a radio-controlled clock that listens to WWV rather than using the internet, GPS, or today's consumer WWVB receivers. If synchronization fails, the clock can still display time from its local oscillator but will not correct itself from WWV.
