Up for sale UR3LMZ
transverter with high dynamic range. 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-12 chip with whopping dynamic range IP3 + 17dBm typ.With this transverter you can operate on the 432 mhz band using any type of the HF radio at 28 mhz. This item very nice working with SDR and FLEX radios with a spectrum Waterfall.
Complete with tested and adjusted in laboratory the transverted board has the english description which contains the circuit of the transverter and the circuit of the simple attenuator board.

To get the transverter worked you have to do some soldering works with a cables, wires and connectors. Probably some instruments would be required. Does not include the interface module, heatsink, power and RF connectors, wires or cables.
I am testing the transveters before putting them in a shipping box. If you would not be satisfied with the transverter board then you ship it back and I refund your money.
