Abstract
Apparatus is provided for automatically compensating for frequency drift in a digitally tuned varactor tuner. An Automatic Frequency Control signal for tuning the varactor tuner is produced in response to the direction of a tuning error. A signal level detector is used to inhibit the AFC signal when weak signals are being tuned by the varactor tuner thereby preventing continuous searching by the tuning system.
