This model was sold as the budget model and was essentially a Heathkit GC-1005. It could be wired either in 12 or 24 hour format. AM / PM alarms can be set with a seven minute snooze interval. Accuracy depends in 50 / 60 Hz power line. The clock is built around an MOS/LSI integrated circuit.
Unlike the Heathkit GC-1005, this model applied 180 V to the keep-alive cathode on each display in order to reduce flickering.

Nice attempt at time/frequency reference

Heathkit GC-1094, Electronic Clock

Built as a kit from Heathkit. Build was no problem, built in tuning aid. Functioned only if had good antenna. It would take a long time for it to lock on to one of the WWV 2.5, 5, 10 and 15 MHz signals from Colorado. The device wold provide a display of the exact time to 1 tenth of a second. It also provided a 10 MHz reference signal for use by devices that had that optional input. Lock function required it to scan for receivable WWV signal, then decode the transmitted coded signal. When it eventually locked, then it wold display the exact time and provide the 10 MHz signal. If it lost lock, it would have reinstate scan. If lock was held long enough, the internal ref oscillator would be auto trimmed, providing an accurate clock with reduced accuracy. Used it for many years as my main station clock.
