Could be a relay, however.... The most common source of intermittents is cords and connectors that are either only partially connected or have had wires stressed past breaking but held together intermittently by insulation, or were never soldered, or were poorly crimped in manufacture.
Banging on the K3 jiggles all the connections on the back of the K3. Then there's RCA connectors not pushed in all the way or with too-short pins for the socket and BNC connectors not twisted home. RULE OUT the connections before tearing apart your K3. Then inside there are the TMP mini coax connectors inside the K3 not seated properly. Then pin connections to reseat several times. All these before relays. Relays will usually close again by repeatedly going TX RX TX RX TX RX.... Don't ask me how much I tore apart before I figured it out or how close I came to putting the K3 in the shipping box...... 73, Guy K2AV On Mon, Apr 3, 2017 at 4:43 AM LA7NO <[email protected]> wrote: > Hello group, > > I have several times experienced that the K3 receiver goes 100% dead.
