144 to 28 MHz High Dynamic Transverter.
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 144 mhz band using any type of the HF radio at 28 mhz.
It is transverter completely ready to operation, you don’t have need something to solder and to complete.
Easy to use!!! It is easily joined to any transceiver. Just connect this transverter to the ANT and PTT connector on your radio, and then connect HF and VHF antennas.
It isn’t necessary to do any switchings!!!
Just power on transverter the tumbler on its front panel – you in VHF band.
Switch off a transverter – you on HF again.
This item very nice working with SDR and FLEX radios with a spectrum Waterfall.
Complete with tested and adjusted in laboratory the transverted has the english description which contains the circuit of the transverter.
