Jorge, 1. Measure the wire resistance in respect to ground and it should show a resistance a little bit higher than your termination value. This will check for breaks in the wire, 2. Put a temporary

If you see no dip in the PA current then check and see if the tuning capacitor padding capacitor is open or disconnected. Check the leaf on the band switch that corresponds to the `160 meter position
