I eceived the KFL1-4 kit on saturday and 2 hours later made my 1st QSO with N6RO on the contest on 21Mhz. Getting 7W out on all bands. But more interesting with the 2 band module on 40m I could not work in the evening without attenuator with a dipole. With the new module I dont need attenuator anymore certainly du to better filter shapes. So I would recommend this upgade for the european fiends 73,s F6DUK Hubert ROTH
