The Model SEQ-QSK High Speed Transmit/Receive Sequencer is a second generation microprocessor controlled sequencer with its origins from the SEQ-1 microwave sequencer product line. A one second Heartbeat is used to give a visual indication that the SEQ-QSK is functioning properly, and four green LED’s give a visual indication of the sequenced step operations. Delay times for the sequencers steps is programmable, even while in circuit.
Today’s Amateur operator likes the ability of fast break-in operation during contest operation, as well as during normal everyday operation. The SEQ-QSK provides this ability by allowing very high speed sequenced switching of both the Tranceiver and high power amplifier. Full VOX break-in and CW break-in operation are fast with no missed syllables, dots or dashes. Programmable delay times from 32 milliseconds to as little as 1 millisecond per step may be selected to match relays in your system.
