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.

- 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
- 10 MHz GPS-Frequency Standard (ID Elektronik, DK2DB)
- 10 MHz GPS-Frequency Standard (ID Elektronik, DK2DB)
