That's certainly a good test. If it tunes successfuly on the dummy load on
all bands, it may just mean that the yaesu tuner has less range than the
Kenwood. I was astonished at the difference in tuner performance between
the TS-440 and the K3. The K3 tuner handles things even the Dentron Super
Tuner won't. I think tuner range can vary greatly among built-in tuners.
Good luck with it. Lou WA3MIX
