Hi Jun,
If you haven't tried it, set RX ISO to ON. This enables an isolation amplifier
that keeps the LO greatly attenuated outside the KX3. The amp draws something

Having the 1 setting so low will also make your signal mushy and hard to
understand. Remember, commercial broadcast quality will widen your signal and
make it difficult to understand in conditions where the atmospheric noise level
is above normal.

Don't forget that KX3 is QRP radio for portable operation. I tried hard to
