50 MHz + 70 MHz to 28 MHz Dual Band Assembled Mean Power Transverter
Add more bands to your HF radio!!!
Dual Band 50 MHz + 70 MHz transverter with high dynamic range and MEAN POWER – 10Wtts on 50 and 10Wtts on 70 mhz 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.
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.
