VC TUNE
The VC tuning circuit drives the variable capacitor
in the receiver RF front end with a high precision
stepping motor, and effectively attenuates the
strong intruding signals that are particularly prob-
lematic in the low band. If there are multiple dis-
turbingsignals, turningtheMPVDringallowsne
tuning of the VC tuning point.
