Auto Tune function not locking

[dl1rf]

I observed with PicoTuner USB a problem that the Auto Tune (Hold) function not always is locking to a new signal.
The tuner switches constantly between "Lock" and "Hunting".
Switching the AutoTuner to "Manual" fixes the problem and Tuner locks.

The problem is under investigation.
