Description

222/21 or 28 MHz Transverter Board with High Dynamic Range and high frequency stability . Up for sale UR3LMZ - transverter with highly stable frequency synthesizer . This allowed us to obtain a long-term stability of 0.2 ppm and to extend the operating range of the transverter 222 - 224 MHz with your HF radio frequency 21 - 23 or 28 - 30 MHz. This model has 2 LO frequencies that can be easily switched using jumpers on the transverter board - 194 and 201 MHz. This allows you to use HF radio with frequencies 21 or 28 MHz . High frequency stability allows you to work in FM, SSB, CW and even digital modes FT8 JT65 and etc . In this transverter model we have added an additional input for external frequency synchronization . If you need very high frequency stability, you can feed a highly stable 10 MHz frequency to a dedicated transverter input. In this case, the stability of the frequency of the transverter board will be determined by the stability of the external 10 MHz generator. This transverter board 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 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 circuit of a simple attenuator board. This sale includes the completely built, tuned and tested transverter board with its schematic diagram and a diagram of a possible connection of this transverter board to your HF radio.
