The complete high performance 1240 to 1300MHz Transverter is constructed using three separate Kits, and takes around 8 hours to construct and tune. A large number of SMD components are used to make the Transverter compact and predictable in performance. The design uses a low noise PHEMT amplifiers, high level +17dBm mixer for good strong signal handling and a cleaner transmit signal on the 23cm band. Mini-Kits designed tuneable filters have been used that provide high local oscillator rejection and low spurious output.  Please refer to the EME23-TRV Kit webpage and the 23cm Block Diagram for more information.

Can be used for an up converter for AO-90

EME23-TRV KIT is a basic Kit with a 144MHz IF that includes the 3 x PC boards, construction notes, and all on board components. No connectors or enclosure are included. Requires complete construction and soldering of small SMD components.

EME23-TRV-HW KIT is a basic hardware Kit that includes, 12x M3x8mm metal spacers with studs, 4x M3 nuts, and 4x M3x6mm screws.

For 1296 to 144MHz select the 96MHz crystal, for 1293 to 144MHz select the 95.750MHz crystal, and for 1296MHz to 145MHz use the 95.91667MHz crystal. 

Please refer to the 23cm ( 1296MHz ) Transverter Webpage and 23cm Block Diagram which will explain in more detail what is required to construct a complete Transverter.

Basic Kits Do Not include connectors, miscellaneous hardware, enclosure, and require other Kit products etc. For advanced constructors due to the small SMD components that are used.
