Heathkit IB-1102 Frequency Counter: History, Restoration, Demonstration, Theory

In this video, I document the successor to one of Heathkit's first digital products, their model IB-1102 frequency counter (their first digital product was the IB-101, and then the IB-1101, which looks identical to this IB-1102 but with a lower frequency range).

I cover the history of this model, the few steps I took to restore it to fully working condition, I demonstrate it in operation, I describe the circuit theory of operation.

Early in May 2024, I will be placing my newly CAD drawn IB-1102 schematic, calibration, etc; document on my fileshare webpage, where it may be downloaded: www.serpentwebsite.com/fileshare.htm
