144+432/28 MHz High Dynamic Dualband Transverter to ICOM IC-7610 radiowith high frequency stability and extended band.
UR3LMZ dualband transverter for ICOM IC-7610 radio.
We have installed a highly stable frequency synthesizer in this model. High frequency stability allows you to work in FM, SSB, CW and even FT8 PSK digital modes. This allowed us to obtain a long-term stability of 0.2 ppm and to extend the operating range of the transverter 144 – 150 MHz and 432 – 438 MHz with your ICOM radio frequency 28 – 32 MHz.
We specially designed this transverter for easy connection to ICOM IC-7610 radio. You only need a couple of cables to connect to your radio and you can work on VHF/UHF 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 transverter has an output power of 12 watts on VHF and 5 watts on UHF.
We are
offering completely built and tested in UR3LMZ lab assembled transverter that comes with the
English description which contains the circuit diagram of this transverter and diagram of how you can connect to your ICOM IC-7610.
