Keys nearly any PA Useable with nearly any transceiver Noiseless operation, transistor keying Fast, QSK capable Simple wiring Every transceiver has a keying output for an amplifier – but not all those outputs are capable of keying the high voltages or currents of an amplifier. High voltages or voltage peaks can destroy the keying stage…
The precision crystal heater provides temperature stabilization for crystals. The circuit, which is built on AL2O3 ceramic substrate, has to be mounted on the 40 °C thermostat crystal. Then, the crystal is heated to 40.8 °C with a regulation accuracy of-better than 0.1 °C. This provides high frequency stability. The precision crystal heater is a…
