144/28 MHz High Dynamic Transverter
Board to Flex radios.
UR3LMZ transverter for FLEX radios. We specially designed this transverter for easy connection to Flex radio, SDR and other similar radios. You only need a couple of cables to connect to your radio and you can work on VHF with all kinds of modulation. It is specially developed for severe conditions of reception – contests, DXing, the neighboring powerful broadcasting and amateur stations. The mixer is made on special HI-frequency ADE chip with whopping dynamic range IP3 + 17dBm typ. We made some improvements, improved the circuit, and now the board has an output power of 15 watts !!
We are
offering completely built and tested in UR3LMZ lab board that comes with the
English description which contains the circuit diagram of this transverter and diagram of how you can connect to your Flex.
