144 MHz + 432 MHz to 28 MHz Dual Band Highly Stable QRP Transverter board.
UR3LMZ Dual Band 144 MHz + 432 MHz transverter board 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 chip with whopping dynamic range IP3 + 17dBm typ.
We have installed a highly stable frequency synthesizer in this model. This allowed us to obtain a long-term stability of 0.2 ppm. High frequency stability allows you to work in FM, SSB, CW and even digital modes (FT8, JT65 and etc) with output power 0.25watt on 144 and 432.
With this transverter board you can operate on the 144 mhz and 432 mhz bands using any type of the HF radio at 28 mhz. This item specifically designed and very nice working with SDR and FLEX radios with a spectrum Waterfall – has separately in/out on 28 mhz and separately out 144 mhz and 432 mhz.
This transverter board is fully tested and configured in the UR3LMZ laboratory, has the english description which contains the circuit of the transverter
