144MHz to 28 – 21 MHz Transverter
Board with High Dynamic Range, high frequency stability and extended band.

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 137 – 155 MHz  with your HF radio frequency 21 – 32 MHz. This model has 4 LO frequencies that can be easily switched using jumpers on the transverter board – 116 118 120 123 MHz. This allows you to work in an extended range of 137 – 155 MHz or use HF radio with frequencies from 21 MHz. You can easily plug in your CB 26 MHz radio and work on 144. High frequency stability allows you to work in FM, SSB, CW and even digital modes FT8 JT65 and etc.
