The EME166 Sequencer replaces the very popular EME66 Kit that has been produced for well over 10 years. The New version makes connection to other circuitry much easier due to a single 10 way header connector on the board. The Sequencer can be used to control Transverters with various component like antenna relays, power amplifier, or receive pre-amplifiers. It is also suitable for sequencing the switching of high power RF amplifiers with a transceiver. The circuitry incorporates both DC and RF sensed inputs that can be used to control the switching of the sequencer from RX to TX mode. The sequencer suits Transverters with either a single, or dual I/F connections. The circuitry uses a PIC micro-controller and MosFET switches, and has over voltage and current protection.

The Product image shows a fully constructed EME166 KITB  product.  Please refer to the Options Tab for the descriptions of the various products available.

Please Note: There is a minimum 2 working day delay to construct built products before they are shipped.

EME166 KIT is a basic Kit that includes the PC board, construction notes, and all on board components. No connectors or enclosure are included. Requires complete construction and soldering of SMD components.

EME166 KITB is a fully constructed and tested board with 2 x female SMA33 connectors fitted. If you have a Transverter that has separate RX and TX IF connections, then you will need to order an additional SMA33 connector.

EME166 PCB Only includes the PC board and Kit construction notes. No on board Components are included.

If you have a Transverter that has separate RX and TX IF connections, then you will require 3x SMA33 connectors.

Kits Do Not include connectors, miscellaneous hardware, or an enclosure. For advanced constructors with some experience with SMD components.
