RF µTuning Kit

The RF µTuning Kit provides ultra-sharp RF selectivity for the front end of the transceiver. Very high Q is made possible by the narrow-band design. Three RF µTuning Kit are available. The MTU-160 covers the 1.8 MHz band. The MTU-80/40 covers the 3.5 and 7 MHz bands. The MTU-30/20 covers 10.1 and 14 MHz bands.
