222 MHz + 440 MHz to 28 MHz Dual Band Assembled Mean Power Transverter. Add more bands to your HF radio!! With high frequency stability and extended bands. We have installed a highly stable frequency synthesizer in this model. This allowed us to obtain a long-term stability of 0.2 ppm and to extend the operating range of the transverter 222 – 226 MHz and 440 – 450 MHz with your HF radio frequency 25 – 30 MHz. High frequency stability allows you to work in FM, SSB, CW and even digital modes (FT8, JT65 and etc) with output power 8 watts on 222 and 3.5 watts on 440. 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. Chip with whopping dynamic range. This transverter includes everything you need to use in conjunction with a HF transceiver with output power of 5-10 watts. Contains the input attenuator and the switch of the bypass on the HF antenna. In the bypass mode, the permissible power is 100 watts. When turning the transverter power on, the HF antenna is turned off and the transverter output is connected. The PTT control of the transverter is automatic with RF power. Due to the automatic switching mode of the attenuator when the RF is applied, even a power of 100 watts, randomly applied to the input, will not be dangerous. Then only set the optimal power of 5-10 watts, and that’s it. For SSB, the transmission is held in speech pauses, and the TX to RX after the HF removal is about 0.5 sec. This transverter is fully assembled and configured in the UR3LMZ laboratory. It has a strong aluminum box. All inscriptions are marked with a modern laser engraving method. The inscriptions are not erased and have a very beautiful appearance. Information about this transverter. 226MHz and 440…450Mhz. DC current is 12V to 14V. Current consumption 3A (TX).
