In this video, I document the successor to one of Heathkit's first digital products, their model IB1102 frequency counter (their first digital product was the IB101, and then the IB1101, which looks identical to this IB1102 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 IB1102 schematic, calibration, etc; document on my fileshare webpage, where it may be downloaded: www.serpentwebsite.com/fileshare.htm
