The MKU 57 G4 is our new 6cm transverters evolution step. It features the standard IF frequencies 144 / 146 MHz and 432 / 434 MHz in one module. The IF frequency can be setup up by the customer with jumpers. The high-quality VCTCXO oscillator guarantees an excellent frequency stability without external reference frequency. For even higher stability requirements the external 10 MHz reference frequency input can be used.

Find a detailed description under downloads.
  • User selectable IF (2m / 70 cm)
  • Local-Oscillator with high frequency stability VCTCXO
  • Additional input for 10 MHz reference frequency
  • Big attenuator at the IF input for input power up to 5 watts
  • Fuses are self-resettable (polyfuses)
  • Super low noise converter in the receive path
  • Transmit gain and receive gain separately adjustable
  • Control output for additional amplifier stages or a coaxial relay
  • PTT can be switched by voltage on the IF connector or by connecting the PTT pin to ground
  • Detector output (DC voltage) for monitoring the output power
As a 10 MHz frequency source we recommend the 10 MHz GPS-Frequency Standard by ID Elektronik, DK2DB
