A tuneable radio and method for automatically adjusting the seek sensitivity alignment for seek operations. The radio has a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting from a plurality of radio wave signal channels. A detector detects signal strength of the received radio wave signals, and a seek input allows a user to initiate a seek operation to select a signal channel having a signal strength exceeding a seek sensitivity threshold. A controller calculates an average signal value and adjusts the seek sensitivity threshold based on the average value. The controller adjusts the seek sensitivity when it is determined that the radio has travelled beyond a minimum distance.

In a preferred embodiment, an apparatus for extending the receiving range of an RF receiver mounted in a non-metallic housing, including: at least one metallic strip attached to an element of the non-metallic housing; and the metallic strip being disposed so as to receive an RF signal transmitted to the RF receiver and air couple the RF signal into the RF receiver.

Apparatus for testing integrated circuit packages has a test circuit, a socket for receiving a standard circuit representing the packages being tested, and a special contact assembly for coupling to the packages being tested. Two sets of contacts in the assembly are permanently connected to the socket and the test circuit respectively, and one set is movable to connect with the other set or to terminals of a package being tested. A handler inserts the packages one at a time into the contact assembly and moves the movable set of contacts into circuit engagement with the package, and then the package is tested by the test circuit. The handler removes the package from the contact assembly and allows the movable set of contacts to engage the other set so that the standard circuit can be tested to verify that the test circuit is functioning correctly. Base data taken on the standard circuit is used to establish a significance band and data periodically taken on the standard circuit is compared with the significance band to determine the amount of drift in the test circuit.
